text: ‘n.d.’ is used in the case no date could be found for the cited sources. Therefore, information security (IT) incidents are defined as “a series of unwanted or unexpected information security events that have a significant probability of compromising business operations and threatening information security” (International Organization for Standardization (ISO), 2011). Along the same lines, cyber incidents refer to a “single or a series of unwanted or unexpected information security events (see above) which occur in a “complex environment resulting from the interaction of people, software and services on the internet by means of technology devices and networks connected to it, which does not exist in any physical form” (ISO, 2012b).

text: The proposed NIS Directive (European Commission, 2013a) is now undergoing the final stage of negotiations between the EU legislative bodies; it is hoped that it will be adopted shortly (Latvian Presidency of the Council of the European Union, n.d.). As recently reported, the “EU Digital Commissioner Günther Oettinger said […] [on 9 November 2015] that an agreement on new, long-awaited cybersecurity legislation is only “days or weeks” away. European Commission, Parliament and Council officials are about to sign off on a compromise deal on the network and security information (NIS) directive, according to Oettinger. […] Luxembourg, the current holder of the 6-month rotating Council presidency, is now trying to push through an agreement in the last weeks before its term ends on 31 December.” (Stupp, 2015).

text: SECTOR RATIONALE FOR INCLUSION IN SCOPE OF THIS STUDY BASED ON THE IMPACT ASSESSMENT Generation, transmission and distribution of energy are highly dependent on secure network and Energy information systems. Major gas and electricity companies for example, suffer increased amounts of cyber attacks motivated by commercial and criminal intent.

text: Key transport infrastructure such as airports, ports, railways, traffic management systems and logistics

text: suffer increased amounts of cyber attacks motivated by commercial and criminal intent.

text: Hospitals and clinics are becoming more reliant on sophisticated ICT systems which need to be secure in

text: order to ensure continuity of service and avoid fatal disruptions.

text: Banks are the backbone of our financial system. They are common targets of fraudsters. The stock

text: Finance and

text: exchange, insurance, retail and investment banking for example, are increasingly adopting networks and

text: information systems and Internet based commerce systems.

text: It is important to ensure the security of Internet companies which provide key inputs enabling important

text: Internet services

text: economic and societal processes. This is essential to preserve trust in the digital ecosystem.

text: Public E-Government and e-participation are increasing with citizen demand for timely and cost-effective services administration and so are the NIS risks for state and local administrations. The risk for public online services to be hindered by NIS problems exist at all levels.

text: Executive Summary

text: Cyber security incidents are constantly increasing in frequency and magnitude, becoming more complex and unconstrained by borders. These incidents can cause major damage to the economy, and hence, cyber security is one of the biggest issues governments and businesses in the European Union (EU) and globally are currently facing. The borderless nature of cyber incidents and attacks, regardless of sector or area, calls for rapid, cross-border and cross-sector responses. Efforts to prevent, better cooperate in relation with, and to be more transparent about cyber incidents must still improve. In the cyber security community, there is currently a strong need for the exchange of data to support the management of vulnerabilities, threats and incidents, as well as other cyber security activities. This study aims to present the regulatory and non-regulatory approaches of EU Member States as well as EEA and EFTA countries to share information on cyber incidents, the different sector regulation challenges of managing cyber security issues, and their key practices in addressing them.

text: This study identifies three types of approaches to share information on cyber security incidents: 1) traditional regulation; 2) alternative forms of regulation, such as self- and co-regulation; 3) other approaches to enable information sharing, such as information and education schemes.

text: The proposed NIS Directive (European Commission, 2013a) and the accompanying Impact Assessment of the European Commission (European Commission, 2013b) identify six key sectors to preserve the good functioning of the internal market. These sectors are public administrations, finance and banking, energy, transport, health and Internet services. The information sharing initiatives in this report were identified and structured based on these criteria.

text: Despite the increasing number of national initiatives to create a legal framework to share information on cyber incidents, the co- and self-regulation approaches seem to be the most used in the EU and EEA/EFTA countries. While traditional legislation appears to tackle information sharing only partially (with the emphasis on breach notification requirements and incident reporting) and in reality not always in a consistent way all over Europe, the major challenges for alternative forms of regulation are the hesitation to share information with external parties and the lack of mechanisms to enforce the rules to share information. Another element that seems to prevent stakeholders from reaping fully the benefits of alternative forms of regulation is that the positive aspects of information sharing within such business communities are not sufficiently clear to encourage their members to participate in the information exchange process. Finally other approaches exist to inform and educate the community on certain topics with the aim to change the behaviour of the stakeholders in the information sharing on cyber incidents. However, these initiatives often take time to reach a wide community and, hence, it is rather difficult to measure their effectiveness in raising awareness and in changing market behaviour towards more transparency.

text: In the context of the information sharing initiatives, it is worth also mentioning the important role of national and governmental CSIRTs. In a number of countries, CSIRTs are (co-)founders of initiatives on information sharing or take an active role in bringing stakeholders together into a constructive dialogue and actions focused on cyber threats and cyber incidents.

text: Throughout the initiatives discussed here, it is pointed out that trust is a key element to enhance information exchange. At present, members of the initiatives identified do not always feel inclined to share information, for a variety of reasons. Hesitation to share and even mistrust may exist, for instance, as a consequence of a lack of interaction between members, or because passive/non-contributing members are not penalised. Another reason may be that conditions to become member of certain initiatives are

text: rather loose. The findings of our analysis also pinpoint cases whereby initiatives are short of members’ buy-in, meaning that they find it hard to convince their members that non-participation in the initiative, and thus no information sharing, will be detrimental to the one who refuses to join. Moreover, the results of the stocktaking concur that most of the co- and self-regulatory schemes at present lack truly enforceable means in order to: a) discourage the reluctance of some participants to share information and b) penalise the members who do not respect the confidentiality rules that the initiative’s stakeholders agreed to abide by.

text: In addition, it must be emphasised that one of the biggest weaknesses of the initiatives discussed herein is that, quite often, the conditions and modalities regarding how the information will be communicated within the members of the initiative, or towards other groups or the public, are not sufficiently defined, unclear or even not well understood. There are cases whereby widely-acknowledged practices in terms of information sharing, such as the Traffic Light Protocol (TLP) are applied within certain initiatives, but other initiatives rely on less-acknowledged practices or even ad hoc rules, such as ad hoc confidentiality agreements or membership clauses.

text: Finally, most of the information sharing initiatives are cross-sector, which means that organisations from different sectors are involved in the information exchange process. However, the finance and banking sector and the public administration sector seem to be the most developed in terms of information sharing as a good number of sector specific information sharing initiatives do gather together stakeholders of these sectors.

text: Core findings of this study are:

text:  The prevalence of traditional regulation, alternative forms of regulation (such as self- and coregulation) and other approaches to enable information sharing on cyber incidents, varies from country to country;  There is a general prevalence of alternative types of regulatory initiatives (co- and self-regulation) in the field of information sharing on cyber incidents;  Different regulatory and non-regulatory approaches bring different challenges with them (as discussed in the following pages of this report);  Trust is a key element for the success of the information sharing on cyber incidents;  National and governmental CSIRTs play an important role in the field.

text: Core recommendations are:

text: 1. EU and national policy makers, law makers and regulators, governmental institutions and administrative bodies (as they have an influence and control on the policy and legislative framework) and the actors of the initiatives (e.g. initiatives’ founding or supporting bodies being CSIRTs or other) should leverage existing self-regulatory and co-regulatory initiatives;

text: 2. European oversight and regulatory bodies competent by sector, European policy and law makers, national regulatory and oversight bodies and standard-setting bodies should harmonise regulation rather than attempt to enact new mandatory rules;

text: 3. National governmental institutions and information sharing initiatives’ facilitators (e.g. CSIRTs or administrative bodies supporting an initiative financially or in another way) should further develop

text: intra- and cross-sector information exchange with the intervention of the government or other

text: stakeholders;

text: 4. National governmental institutions, information sharing facilitators with the support of CSIRTs, and any stakeholder willing to engage in a new information sharing initiative should take advantage of the practices developed by national and governmental CSIRTs;

text: 5. EU and national policy makers including administrative institutions and regulatory and oversight bodies should build upon existing work performed by EU institutions and bodies – including ENISA –

text: and by the EU Member States whenever this is the case, in the field of information sharing on cyber

text: security incidents. In addition, the European Commission (e.g. DG Communications Networks, Content and Technology (DG CONNECT), DG Research and Innovation (DG RTD)) and ENISA should find ways to boost the interactive dissemination of the knowledge and good practices;

text: 6. EU Member States, European Commission (e.g. DG Communications Networks, Content and Technology (DG CONNECT), DG Research and Innovation (DG RTD), DG Internal Market, Industry, Entrepreneurship and SMEs (DG GROW), DG Migration and Home Affairs (DG HOME), DG Joint Research Centre (DG JRC) and DG Energy (DG ENER)), ENISA and current and future initiators, founders and facilitators of initiatives should encourage cross-border cooperation and build joint initiatives at EU level without excluding an international reach whenever possible.

text: 1 Introduction

text: 1.1 Purpose

text: The purpose of this report is to take stock of the regulatory and non-regulatory approaches used to enable cyber security information sharing in the EU, EEA and EFTA countries. A particular focus is given to crosssector information sharing about cyber incidents between different stakeholders (ENISA, 2015a).

text: This report presents firstly the regulatory and non-regulatory approaches to share information on cyber incidents and secondly insights into the different sector regulation challenges of managing cyber security issues as well as the practices of the countries in scope in addressing them.

text: 1.2 Background of the Study

text: As of 2015, ENISA’s core operational activities are aligned with the four Strategic Objectives from the ENISA strategy document and the multi-annual planning for 2015 to 2017, which are summarised in ENISA’s Work Programme 2015 (ENISA, 2014). The work packages (WPKs) in ENISA’s SO4 aim “to enhance cooperation both between the Member States (MS) of the EU and between related NIS communities”.

text: Work Package 4.1 aims at supporting “EU cooperation initiatives amongst NIS–related communities” in the context of the Cybersecurity Strategy of the European Union (European Commission, 2013) (Council of the European Union, 2013) (EU CSS) through two deliverables.

text:  First deliverable (D1) of WPK 4.1 of the ENISA Work Programme 2015 (ENISA, 2014), whose goal is to “develop and provide guidance based on best practice for cooperation between key stakeholder communities”;  Second deliverable (D2) - this study -, the goal of which is to “identify practices of Member States in addressing different sector regulation challenges of managing cyber security issues”.

text: It is in ENISA’s and other EU communities’ interest to gain knowledge in the field of information sharing. Indeed, it is a fact that “communicating incident information to others will foster future cooperation and coordination in incident prevention, prompt rapid reaction to incidents and will improve overall security with the community”. Moreover, the information shared between communities “should be performed to reduce the risks of similar incidents and develop a better understanding of the risks facing the community and any related significant information infrastructure” (International Organization for Standardization (ISO), 2012a).

text: 1.3 Study Objectives and Scope

text: This study aims to identify practices of EU Member States as well as EEA and EFTA countries in addressing different sector regulation challenges of managing cyber security issues.

text: It is important however to clarify that the word ‘issues’ from the ENISA’s Work programme 2015 (ENISA, 2014) is replaced in this report by ‘incidents’ since the term ‘issue’ is rather a broad one and it is usually used in national, EU or international level strategies to talk about long-term ‘problems’, which in most cases refer to ‘a cause of one or more incidents’ (ITIL (IT Service Management), 2007). Besides, for the purpose of this report the term ‘incident’ seems more appropriate as it refers to specific events such as network failures, service interruptions and security breaches (see ‘Key concepts and definitions’ here below for the precise definition of incidents).

text: This report presents the regulatory and non-regulatory approaches of EU Member States as well as EEA and EFTA countries to sharing information on cyber security incidents, the different regulation challenges of managing those incidents within sectors and cross-sectors, and the observed current practices of the Member States in addressing them.

text: 1.4 Policy Context

text: On 7 February 2013, the Commission released the Cybersecurity Strategy of the EU with the subtitle ‘An Open, Safe and Secure Cyberspace’ (EU CSS) (European Commission, 2013) (Council of the European Union, 2013). The strategy defines five short and long-term priorities and actions that involve EU institutions, Member States and industry:

text: 1. Achieving cyber resilience; 2. Drastically reducing cyber crime; 3. Developing cyber defence policies and capabilities related to the Common Security and Defence Policy (CSDP); 4. Developing the industrial and technological resources for cyber security; and 5. Establishing a coherent international cyber space policy for the European Union and promote core EU values. One aspect that can be found in almost every strategic priority is the sharing of cyber security information within and between the private sector, national entities, Member States, and EU institutions (Deloitte, 2013).

text: Since WPK 4.1 of the ENISA Work Programme 2015 (ENISA, 2014) aims at supporting EU cooperation initiatives amongst NIS–related communities in the context of the EU CSS, this study takes the EU CSS as the basis for the identification of main relevant sectors where information sharing takes place and the main relevant areas of cyber security in the chapters to come.

text: According to the EU CSS (European Commission, 2013) (Council of the European Union, 2013), cyber incidents do not stop at geographical borders in the interconnected digital economy and society. Therefore, to address cyber security in a comprehensive way, activities should span across three key pillars which also operate within different legal frameworks.

text: Within the EU CSS, these pillars are Network and Information Security, Law Enforcement and Defence, as depicted in the following figure (Figure 1).

text: These pillars correspond to the strategic priorities of the EU CSS. In addition, the European Union Agency for Network and Information Security (ENISA), the Europol/European Cybercrime Centre (EC3) and the European Defence Agency (EDA) are the three main EU agencies from the perspective of NIS, law enforcement and defence, respectively.

text: These agencies have Management Boards where the EU Member States are represented, and they offer platforms for coordination at EU level.

text: The table below (Table 1) represents a summary view of the relevant elements of these three pillars, their corresponding strategic priorities as deriving from the EU CSS, their corresponding lead agencies active at EU level, and their corresponding legal framework at EU level.

text: 1.5 Target Audience

text: The primary target audience of this report are policy and lawmakers at EU and Member State level, the CSIRT community (in particular national and governmental CSIRTs), the law enforcement community and other operational communities.

text: 1.6 Key Concepts and Definitions

text: In the context of this study, the following definitions apply – see alphabetically:

text:  Co-regulation refers to “a mechanism whereby the legislator entrusts the attainment of specific policy objectives set out in legislation or other policy documents to parties which are recognised in the field (such as economic operators, social partners, non-governmental organisations, or associations)” (European Commission, 2015).  Cross-sector information sharing refers to communication of information between communities established in different sectors (International Organization for Standardization (ISO), 2012a).  Computer Security and Incident Response Team (CSIRT) or Computer Emergency Response Team (CERT) refer to “an organisation that studies computer and network security in order to provide incident response services to victims of attacks, publish alerts concerning vulnerabilities and threats, and to offer other information to help improve computer and network security”. At present, “both terms (CERT and CSIRT) are used in a synonymous manner, with CSIRT being the more precise term” (ENISA, 2015b).  Cyber safety refers to a “condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event in the Cyberspace which could be considered nondesirable” (International Organization for Standardization (ISO), 2012b).  Cyber security refers to “the safeguards and actions that can be used to protect the cyber domain, both in the civilian and military fields, from those threats that are associated with or that may harm its interdependent networks and information infrastructure” and it “strives to preserve the availability and integrity of the networks and infrastructure and the confidentiality of the information contained therein” (European Commission, 2013, p. 3). As highlighted in some previous ENISA work (ENISA, 2014b), in the academic context the “most widespread is the notion according to which cyber-security is identified with information security, which refers to protection of information and information systems against being broken into, used, spread, or subjected to service interruptions, unauthorized changes, or destruction, with the aim of guaranteeing their confidentiality, integrity, and availability.” In a best practice context, cyber security refers to the “[p]reservation of confidentiality, integrity, and availability of information in the Cyberspace”.  Cyber space is a “complex environment resulting from the interaction of people, software and services on the Internet by means of technology devices and networks connected to it, which does not exist in any physical form” (International Organization for Standardization (ISO), 2012b).

text:  Incident (ENISA, n.d., p. 26) is an event that has been assessed as having an actual or potentially adverse effect on the security or performance of a system. Subcategories of incidents are information 8 9 security (IT) incidents and cyber incidents. These terms are often used in an interchangeable manner.  Information sharing means ‘the exchange of a variety of network and information security related information such as risks, vulnerabilities, threats and internal security issues as well as good practice’ (Robinson & Disley, 2010).  Information sharing initiative means “actions taken, in the form of activities or projects which support and solve challenges facing information sharing” (Robinson & Disley, 2010).  Intra-sector information sharing refers to communication of information between communities within the same sector (International Organization for Standardization (ISO), 2012a).  National and governmental CSIRTs are “teams that serve the government of a country by helping to protect the critical information infrastructure. [National and governmental CSIRTs] […] play a key role in coordinating incident management with the relevant stakeholders at national level. They also bear responsibility for cooperation with the national and governmental teams in other countries.” (ENISA, n.d.(a)).  Network and Information Security means “the ability of a network or an information system to resist, at a given level of confidence, accidental events or unlawful or malicious actions that compromise the availability, authenticity, integrity and confidentiality of stored or transmitted data and the related services offered by or accessible via these networks and systems” (European Parliament and the Council, 2013).  Regulation refers to a “rule or order prescribed for management or government; a regulating principle; a precept. [It is a] rule of order prescribed by superior or competent authority relating to action on those under its control” (InterActive Terminology for Europe, 2014).  Sector regulation challenges, in our understanding, is a situation where requirements imposed by an existing sector-specific regulation impedes or precludes the sharing of cyber security threats information by actors in the affected sector.  Self-regulation “typically involves a group of economic agents, such as firms in a particular industry or a professional group, voluntarily developing rules or codes of conduct that regulate or guide the behaviour, actions and standards of its members” (OECD, n.d.).  Traffic Light Protocol (TLP): the basic concept of TLP is widely understood as being a mechanism used in information sharing communities to determine the allowed distribution of information. The TLP is based on the concept of the originator labelling information with colours to indicate what dissemination is allowed by the recipient. Usually, four colours are used:  RED - Personal for Named Recipients Only;  AMBER - Limited Distribution;  GREEN - Community Wide; and  WHITE - Unlimited. The concept was originally developed by the UK’s Centre for the Protection of National Infrastructure (CPNI). However, since then a number of slightly different variations have appeared and are currently in use (Millar, 2015).

text: 2 Methodology

text: This chapter details the methodology applied and the choices made to collect information for this study.

text: As a first step in this study, the scope and a regulatory framework were determined and refined in order to increase the focus on the information sharing elements that are most relevant from a regulatory and nonregulatory approach viewpoint. For this purpose the most relevant sectors where information sharing takes place were selected based on the proposal for an NIS Directive (European Commission, 2013a) , which identifies key sectors. The names of the key sectors were then formalised based on the NACE (Nomenclature des Activités Économiques dans la Communauté Européenne) structure (Eurostat, 2008). Afterwards, possible regulatory and non-regulatory approaches to share information were distinguished, such as traditional regulation, alternative forms of regulation (co- and self-regulation) and other approaches (e.g. information and education schemes).

text: As a second step in this study, a fact-finding exercise took place with the objective to identify pertinent information on the subject matter of this study (i.e., take stock of initiatives or regulation EU and Member States have been implementing to share information related to cyber security incidents and to address relevant challenges). This task has been carried out through: 1) an extensive desk research that included, amongst others, public information sources; 2) interviews with a selected group of stakeholders involved in information sharing initiatives; and 3) interviews with experts from the selected sectors having hands-on experience in information security and who have reflected on the subject matter of this study.

text: Concurrently, the collected information and research findings were validated with the support of the network of National Liaison Officers (NLOs) of ENISA. During the fact-finding exercise, a number of countries were identified whereby either the first findings of the desk research, or other factors (see Chapter 2.4) justified, according to the project team, additional collection of information and/or a more indepth review.

text: 2.1 Desk Research

text: A part of the information used in this study has been collected via desktop research on publicly available information sources. These sources were, for example, official websites of initiatives/organisations, reports published by organisations or other external parties, public databases, research engine search results, various publications and relevant presentations made during CSIRT conferences or events. The desk research was used to collect the initial part of the data. Then, based on the interviews and the feedbacks received, a second desk research has been carried out to find more specific information.

text: For example, the result of the first desk research that was carried out is a list of relevant recent initiatives that have a strong component related to cyber security incident sharing - see the table below (Table 2).

text: Table 2 above does not represent an exhaustive list of information sharing initiatives in EU Member States, EEA and EFTA countries, or at global/international level. This table has been extended and refined during the fact-finding exercise and has been used as working tool for the review of the information by the National Liaison Officers (NLOs) of ENISA.

text: 2.2 Interviews with a Selected Group of Stakeholders Involved in Information Sharing Initiatives

text: Interviews were performed with key stakeholders involved in information sharing initiatives (i.e. mainly EU-wide or EU-focused projects aimed at further facilitating information sharing activities between stakeholders, global initiatives or partnerships at Member State level).

text: The objective of these interviews was to collect first-hand information on the regulatory and nonregulatory approaches used in five EU Member States, five EU projects and by three global/international organisations – approached to share information and to manage challenges related to cyber security issues. The involved stakeholders were jointly identified by the study team via desktop research and via inquiry with ENISA and industry experts. Key criteria in selection of these stakeholders were the level of engagement in an information sharing initiative, the level of maturity of the initiative in which they are active and the experience or the level of knowledge on the information sharing topic.

text: Regarding the methodological approach followed for the interviews held with the involved stakeholders, it is relevant to mention that the approach chosen by the study team was to use a questionnaire, structured as follows:

text:  Part 1: General questions about the initiatives and the sectors involved in the sharing of information.  Part 2: Questions on the approaches to share information, considering the following three types:  Traditional regulation;  Other forms of regulation;  Other alternatives to share information.  Part 3: Questions on the challenges to share information and the approaches to address them.

text: A sample questionnaire, used for the interviews with a selected group of stakeholders involved in information sharing initiatives, can be found in Annex 2.

text: 2.3 High Level Review of Regulatory and Non-regulatory Approaches

text: A high-level review of regulatory and non-regulatory approaches used in the EU and EEA Members States and at global level to share information on cyber incidents was performed by the study team via an extensive desk research. More than eighty (80) initiatives and organisations and more than fifty (50) national and governmental CSIRTs involved in information exchange on cyber incidents were identified at EU and EEA level.

text: The collected information was validated with the support of the network of National Liaison Officers (NLOs) of ENISA. More specifically, these Member State representatives gave feedback on the completeness of the initiatives and relevant organisations (including national and governmental CSIRTs) listed as well as on the correctness and relevance of the information associated to their Member State.

text: 2.4 In-Depth Review of Regulatory and Non-regulatory Approaches Used in Some Selected Countries

text: An in-depth review was performed via desktop research to identify regulatory and non-regulatory approaches used in selected EU Members States to share information on cyber incidents and practices to address sector regulatory challenges of managing cyber security issues. This in-depth review focused on a selection of eight EU Member States – the selection was based on the following criteria:  The size of the Member State and the specifics of the national regulatory system concerning cyber security;  The geographical location of the country (fair geographical representation across Europe);  The type of legal system in force: common or civil law;  The level of government centralisation: federal or centralised;  The relative strength of the cyber legal framework of the Member State considered (taken the EU level as the average one setting the minimum requirements);  The level of maturity of the national cyber security policy of the country, notably the appointment of national and governmental CSIRTs;  The active role of the sector regulators or the business community concerned with information sharing, notably whether self- or co-regulatory efforts have been undertaken; and  Actions and specific initiatives a Member State has taken in relation to information sharing at sector or cross-sector levels. Based on these criteria, the following EU Member States were selected for the in-depth review – see below in alphabetical order:  Cyprus, a Southern European Member State with a common law tradition;  Estonia, a Baltic Member State with active government involvement in regulating cyber security (established national and governmental CSIRT) and exposure to nationwide cyber attacks (2007);  Finland, for its active and centralised government involvement in information sharing and geographical location (Northern EU Member State);  Germany, as it is a large, decentralised (federal) Member State with a strict cyber legal framework;  The Netherlands, as it has many co-regulatory information sharing initiatives, including at sectoral level;  Poland, as it is a large Eastern European Member State with a strict cyber legal framework (e.g. information security officer requirement);  Spain, as it is a large Southern European Member State with many examples of self-regulatory initiatives for sharing cyber threat information; and  United Kingdom, a common law Member State with many information sharing initiatives in place.

text: As a result, chapters three, four and five of this document present the sectors selected for the study (Chapter 3), the areas of cyber security (Chapter 4) and the identified possible regulatory and nonregulatory approaches to share information on cyber incidents (Chapter 5). Chapter 6 summarises the main findings of the study. Finally, the last chapter (Chapter 7) presents preliminary conclusions and recommendations.

text: 3 Sectors Where Information Sharing Initiatives on Cyber Security Incidents Take Place

text: This chapter presents the main relevant sectors where information sharing about cyber incidents takes place among the different stakeholders.

text: 3.1 Selection of Relevant Sectors Based on the Relevant Policy Context

text: One of the main actions of the EU is the proposed NIS Directive (European Commission, 2013a). This proposal is accompanied by an impact assessment (hereafter ‘the Impact Assessment’) (European Commission, 2013b) that covers policy options to improve the security of the Internet and other networks and information systems underpinning services which support the functioning of our society. It identifies six (6) sectors (according to the NACE rev.2 classification (Eurostat, 2008)) for which the correct functioning of NIS is key in order to preserve the correct functioning of the internal market. These identified sectors are the following: public administrations, finance and banking, energy, transport, health and Internet services enabling key economic and societal processes, such as e-commerce platforms and social networks.

text: The infrastructure and service providers in these sectors are particularly vulnerable to cyber attacks and to other categories of cyber incidents, in particular due to their “high dependence on correctly functioning network and information systems” and “their essential role in providing key support services for our economy and society, including health, safety, security and the economic and social wellbeing of people”.

text: In summary, the Table 3 below identifies the sectors identified in the Impact Assessment where “the wellfunctioning of NIS is key to preserve the well-functioning of the internal market”.

text: However, it is important to note that the Impact Assessment does not cover EU Member States’ activities concerning national security and defence. In addition, according to Article 1 of the ENISA’s Regulation, “the objectives and the tasks of the Agency shall be without prejudice to the competences of the Member States regarding network and information security and in any case to activities concerning public security, defence, national security” (European Parliament and the Council, 2013). Therefore, national security and defence matters were specifically considered as not within the scope of this study. Through the research work performed by the study team, we found a number of relevant information sharing initiatives in other sectors such as the water, pharmaceutical or nuclear sectors that are worth analysing and worth mentioning due to their specific elements that may be relevant for the cyber security domain. For example, we observed that the UK CPNI organises the Water Security Information Exchange (WSIE) and the Pharmaceutical Industries Information Exchange (PIIE) exchange information on cyber attacks between actors in the these sectors in the UK. Similarly, the National Cyber Security Center (Nationaal Cyber Security Centrum (NCSC)) in the Netherlands has put in place the Water ISAC and the Nuclear ISAC which are also an important building block of the information sharing initiative(s) in these Dutch sectors. Therefore, wherever relevant, references have been made in the study, concerning initiatives and practices in the various sectors, in addition to those stemming from the Impact Assessment.

text: 3.2 Identification of Information Sharing Initiatives per Sector

text: The purpose of this chapter is to provide examples of information sharing initiatives within and across the sectors identified in the chapter above. This is accomplished by listing a number of existing initiatives currently involved in exchanging information about cyber incidents in those sectors at EU and MS level. For this purpose, the following definition of an information sharing initiative is used: “Information sharing initiatives are actions taken, in the form of activities or projects which support and solve challenges facing information sharing” (Robinson & Disley, 2010). In order to illustrate examples of information sharing initiatives, two lists have been created. The first one (Table 4) lists intra-sector information sharing initiatives, while the second one (Table 5) shows examples of cross-sector information sharing initiatives at Member State or EU level. These examples have been identified via the performed desk research, and they should be considered as a representative, but non-exhaustive, list of such initiatives. Please note that the initiatives identified in Tables 4 and 5 are primarily used here to highlight the sectors concerned (energy, transport, etc.). Further explanations on a number of initiatives mapped to these sectors are discussed in more detail in Chapter 6 of this report. Table 4 lists a number of examples of intra-sector information sharing initiatives occurring in the sectors in scope and in several Members States.

text: Furthermore, Table 5 below lists examples of cross-sector information sharing initiatives.

text: 4 Areas of Cyber Security Relevant for the Identified Sectors

text: This chapter aims to present the main areas of cyber security that are relevant for the selected sectors. For this purpose, and for the clarity of the readers, the two key concepts of ‘cyber space’ and ‘cyber security’ have been used. The definitions can be found in Chapter 1.6 ‘Key Concepts and Definitions’. According to the EU CSS, major cyber incidents are likely to have an impact on EU governments, business and individuals. However, the response mechanisms will differ depending on the nature, magnitude and crossborder implications of the incident. A number of categories of major incidents are defined in the EU CSS in the context of EU support in case of a major cyber incident or attack. These are visible in the left column of the table below (Table 6). Some cyber security areas can relate to multiple categories of cyber incidents.

text: Furthermore, cross-sector information sharing communities are usually established based on some common interest, such as the nature of the shared information. For this reason, we have identified relevant areas of cyber security that apply per category of cyber incidents - visible in the right column of the table. Critical Infrastructure Protection is considered as an area of cyber security because the protection of infrastructure can also be achieved via the information sharing on cyber incidents. For example, it seems that the members of the Thematic Network Critical Energy Infrastructure Protection (TNCEIP) initiative share information on relevant cyber issues that are related to the operational security of their physical assets. Moreover, incidents relating to a crime and incidents involving personal data are both related to cyber safety. Indeed safety and security are required in cyber space and these can be achieved by sharing these two types of incidents. It is also important to note that cyber security builds upon information security, application security, network security, and Internet security, all of these being considered its fundamental building blocks (International Organization for Standardization (ISO), 2012b). However, cyber security is not strictly speaking synonymous with Internet security, network security, application security or information security. Therefore, for the purpose of this study, these are not considered areas of cyber security. Moreover, other criteria could have been chosen to identify areas of cyber security. Nevertheless, the approach derived from the EU CSS seems to be the most suitable

text: approach to follow for the purpose of this study because in the context of the EU CSS, ENISA is tasked to support Strategic priority 1 - Achieving cyber resilience (see Chapter 1.4 Policy Context). In addition, anther reason to justify the use of the EU CSS in determing the criteria is the fact that the EU CSS is aligned with other EU policy intiatives, and is also a reference for other national and European policy intitiatives.

text: 5 Possible Regulatory and Non-regulatory Approaches to Sharing Information on Cyber Incidents

text: This chapter addresses possible regulatory and non-regulatory approaches that EU Member States and EEA and EFTA countries may adopt to regulate information sharing about cyber incidents. Taking stock of international studies and initiatives, including an OECD report (OECD, n.d.), we distinguish between three main clusters: 1) Traditional regulation 2) Alternative forms of regulation, such as self-regulation and co-regulation, and 3) Other approaches to enable information sharing, such as information and education schemes.

text: Each approach is illustrated in this study by examples at EU, national or international level. However, these examples constitute here a representative, but non-exhaustive, list of initiatives or approaches that were identified during the project analysis. In particular, it is not always easy to make a clear distinction between the co-regulatory trend, selfregulation and other approaches to enable information exchange. The main reason for this is that, in general, there are no widely-accepted and formal criteria to distinguish between them. In addition, the concepts of co-regulation and self-regulation are constantly evolving in practice, under the influence of market practices and the regulatory culture of each region or country. Therefore, the difference between co-regulation and self-regulation seems quite small as these approaches often comprise a regulatory basis.

text: 5.1 Traditional Regulation

text: A response of governments to a policy issue is often to regulate by setting legally binding rules that all citizens or companies, or indeed a subset thereof, need to comply with. A general definition of ‘regulation’ is “A rule or order prescribed for management or government; a regulating principle; a precept. [It is a] rule of order prescribed by superior or competent authority relating to action on those under its control” (InterActive Terminology for Europe, 2014). ‘Command-and-control’ is one of the most well-known examples of traditional regulation approaches (Baldwin, Cave, & Lodge, 2012). Traditional regulation is commonly referred to in the EU as ‘hard law’ (European Commission, 2015), implying the adoption of coercive rules by an authority, which has the competence and power to enforce compliance. Traditional regulation might not be the most effective or cost-efficient solution to policy issues (European Commission, n.d.) (OECD, n.d.). The OECD (OECD, 2012), the EU, and US regulators such as the Federal Trade Commission (FTC) (Federal Trade Commission, 1998) therefore advocate wherever possible the use of alternative forms of regulation, which is referred to in the EU’s recently published Better Regulation package as ‘soft’ regulation (European Commission, 2015). In the EU, the proportionality (Bradley, 2011) and subsidiarity (Eur-Lex, 2010) principles govern the choice of instrument, leaving traditional regulation as the preferred option only in case this is proportionate to the policy goal and this goal cannot be achieved at a lower level of government (e.g.

text: Member State, regional, municipal level) or through alternative forms of regulation. In reality, this has led to a proliferation of alternative soft forms of regulation. In Chapter 6.1 we list the main forms these approaches can take - by no means an exhaustive list or strict typology.

text: 5.2 Alternative Forms of Regulation 5.2.1 Co-regulation

text: Co-regulation is “a mechanism whereby the legislator entrusts the attainment of specific policy objectives set out in legislation or other policy documents to parties which are recognised in the field (such as economic operators, social partners, non-governmental organisations, or associations)” [underlining added] (European Commission, 2015). As such, the degree of legislative backing and involvement of government is the main element that differentiates co-regulation from self-regulation (OECD, n.d.). A representative example of co-regulation can be found in standardisation within the Information and Communication Technologies sector (ICT) which stemmed from the EU Regulation 1025/2012 on European Standardisation (European Parliament and the Council, 2012b). This sets the legal framework in which the different actors in the standardisation system can operate. These actors are the European Commission, the European standardisation organisations (CEN/CENELEC, ETSI), industry, small and medium-sized enterprises (SMEs) and societal stakeholders. EU Regulation 1025/2012 aims at setting up an effective and efficient standardisation system within the EU “which provides a flexible and transparent platform for consensus building between all participants and which is financially viable” (European Parliament and the Council, 2012b). Given that standards can have a broad impact on society, in particular on the safety and wellbeing of citizens, the efficiency of networks, the environment, workers’ safety and working conditions, accessibility and other public policy fields, the EU legislator deemed it “necessary to ensure that the role and the input of societal stakeholders in the development of standards are strengthened, through the reinforced support of organisations representing consumers and environmental and social interests” (European Parliament and the Council, 2012b).

text: 5.2.2 Self-regulation

text: Self-regulation “typically involves a group of economic agents, such as firms in a particular industry or a professional group, voluntarily developing rules or codes of conduct that regulate or guide the behaviour, actions and standards of its members” [underlining added] (OECD, n.d.). In self-regulation, this group is also responsible for enforcement and compliance amongst its members. There are different forms of self-regulation, but it usually takes the form of market-driven initiatives. A non-governmental organisation, a representative body or a professional association may take such an initiative, without specific regulation having foreseen the creation of such a group. It may take the shape of codes of conduct, or ethical codes or industry protocols. The main challenge for self-regulation is ensuring that the desired policy outcome is achieved. The lack of a legal basis means that conventional enforcement mechanisms associated with regulation are not available to enforce compliance. Thus, in all self-regulatory initiatives which lead to the adoption of certain rules, such as the ones described in the next chapter, the adoption of such rules by the market stakeholders remains voluntary. When the market stakeholders are members of the self-regulatory group/forum/community having produced the said rules, then, in principle, members are committed to abide by the rules. However, the enforcement power (or the power to ban) of the self-regulatory instruments upon their members is generally low (e.g. relevant sanctions in terms of non-compliance or in case a member breaks the rules are either not specified or generally weak).

text: 5.3 Other Approaches (Information and Education)

text: This cluster covers approaches embedding educational and awareness-raising elements aiming to enhance the knowledge of a stakeholder community on a specific subject matter and, hence, to improve coordination of actions and information sharing. Information and education instruments “work to change behaviour through the provision of greater information or by changing the distribution of information; that is, making information that may be available to some businesses and consumers available to others” (OECD, n.d.). It is worth mentioning that in the field of this study, stakeholders targeted by this kind of approach are organisations, cyber security experts, ISPs, CSIRTs, companies but also any group of citizens willing to share information on cyber incidents. There are cases where information sharing under this stream remains informal and voluntary although it is organised in a quite practical and interactive manner. Interesting examples in this area are cooperative work and stakeholders’ initiatives that are taking shape under the guidance and training support of 47 48 ENISA. Cyber crisis cooperation , relevant training exercises and incident simulations that stakeholders undertake with the objective to test and foster the resilience of communications networks, including against IT/cyber threats, fall therefore under this stream of ‘other approaches’ (see also Chapter 6.3 for relevant examples). Last but not least, we may integrate in this cluster bilateral discussions on cyber security and information exchanges that take often place between two stakeholders or within the members of informal stakeholder groups. These bilateral or multilateral exchanges of information happen on a completely informal basis with no external communication (e.g. no formal website exist presenting the initiative) and the information sharing is based on mutual trust between the participants and without any expectation of taking up any formal action unless in cases where activities have been agreed upon based on a ‘closed user group’ contract or under ‘gentlemen’s agreement’. Although it is difficult to formally measure the effectiveness of such informal, ‘closed user group’ approaches in the study, we deem it worth to mention them here, in the cluster of ‘other approaches’, for the sake of completion of this report.

text: 5.4 From Regulatory to Non-regulatory Approaches: a Summarising Table

text: Table 7 below illustrates the main possible approaches to regulate or promote information sharing about cyber incidents, and shows the range of possibilities that exists between regulatory and non-regulatory approaches (see arrow at the end of the table). As stated before, due to the difficulty to draw a clear line between co- and self-regulation, certain initiatives may be considered to be qualified as both self- and coregulatory. Some examples of initiatives mentioned in the Table 7 are described in more detail in Chapter 6.

text: REGULATORY NON-REGULATORY

text: APPROACHES

text: 6 Member States Regulatory and Non-regulatory Approaches for Cyber Security and Practices of Member States

text: Based on the high-level review that was carried out, a number of initiatives per approach were identified. The initiatives identified were collected based on several criteria. First of all, we targeted the 28 EU Members States and the EEA/EFTA countries, namely Iceland, Liechtenstein, Norway, and Switzerland. We also focused on relevant initiatives being shaped beyond the local territories, notably at EU and global level. Secondly, we looked into initiatives that focus on information related to incidents, threats, vulnerabilities and all other topics related to this specific part of cyber security. Thirdly, we selected to include in this overview the initiatives or organisations presenting a certain level of maturity (at least two years of existence). As explained in Chapter 5, certain initiatives might fit into more than one approach due to the difficulty to always clearly distinguish between the different approaches. The initiatives listed in this chapter have been classified based on their main characteristics. However, they might also find similarities with another approach.

text: 6.1 Traditional Regulation in Practice

text: Based on the findings of our analysis it appears that only a few EU Member States (approximately one quarter of them) have set up traditional regulation in the field of cyber security information sharing. In particular, in light of the findings of our research, it appears that a substantial part of traditional regulation which triggers information sharing stems from notification requirements enshrined in the European and local regulation. A first example in this regard is a European legislative act, the EU Directive on the protection of personal data in the electronic communications sector, known as the ePrivacy Directive which aims at protecting the privacy of personal data in the sector of electronic communications (European Parliament and the Council, 2012a). Based on a requirement of this directive, electronic communications service providers are required by law in all EU Member States having transposed the directive to empower their respective Data Protection Authorities (DPAs) and, under certain circumstances also their citizens in case of security breaches affecting personal data. Accordingly, all EU Member States have passed legislation to bring their laws in line with the notification requirement of the ePrivacy Directive. Illustrations of national measures taken in this respect are the following:  In Slovenia, based on the Electronic Communication Act (Information Commissioner, 2015), the Communications Networks and Services Agency (AKOS) is obliged to notify security incidents and cyber violations to the national and governmental CSIRT (SI-CERT).  Legislative Act in the form of the Telecommunications Law of 10 July 2012 of Belgium states that providers of public electronic communications services are obliged to report any security breach or

text: damage of integrity to the national regulator of electronic communications. (belgiquelex.be - Banque Carrefour de la législation, 2012)

text: Secondly, sector-specific European regulation applicable to electronic communications has defined a notification duty similar to the one described above. Accordingly, based on the Framework Directive (

text: Article 13

text: a) (European Parliament and the Council, 2009), “Member States shall ensure that undertakings providing public communications networks or publicly available electronic communications services notify the competent national regulatory authority of a breach of security or loss of integrity that has had a significant impact on the operation of networks or services. Where appropriate, the national regulatory authority concerned shall inform the national regulatory authorities in other Member States and the European Network and Information Security Agency (ENISA). Moreover, ENISA and the European Commission should receive a report summarising the measures taken to resolve the issues”. As a third example in the area of incident reporting, there is the upcoming NIS Directive (European Commission, 2013a) which is expected also to provide an obligation for market operators in scope of the directive to notify incidents having a significant impact on the security (or continuity) of the core services they supply. The proposed NIS Directive is now under negotiation between the EU legislative bodies. As with the ePrivacy directive, the NIS directive – once adopted – will need to be transposed in national laws, through primarily a legislative act (being a law, a decree or other regulatory act) for the notification obligation to become enforceable upon operators. A fourth example related to notification obligations derives from another European legislative act that has been enacted recently, the Electronic identification and trust services (eIDAS) Regulation (European Parliament and the Council, 2014). Article 19 of this regulation stipulates that trust service providers should report “any breach of security or loss of integrity that has a significant impact on the trust service provided or on the personal data” to the relevant supervisory bodies (e.g. national security authority or data protection authority) and in some cases, to ENISA. As the regulation is directly applicable at Member State level without need of transposition, the notification rule enshrined in this legislative act (the eIDAS Regulation) is directly enforced at national level. Apart from these non-exhaustive examples, many other relevant regulatory texts can be cited in the context of mandatory incident reporting, such as the EU General Data Protection Regulation (GDPR) (legislative procedure towards its adoption currently ongoing) and the EU Directive

text: on attacks against information systems (European Parliament, Council, 2013). Besides the above examples of legislative acts with a cross-border impact being imposed by the European legislative bodies, more and

text: more countries are putting in place command-and-control legislation in the field of information sharing on cyber incidents at national level. We can mention the following indicative examples:  The Finnish Communications Regulatory Authority (FICORA) , which the National Cyber Security Center (NCSC-FI) is part of. NCSC-FI is the home of the national and governmental CSIRT in Finland, the CERT Finland (CERT-FI). According to the Information Society Code 917/2014 (Ministry of Transport and Communications, Finland, 2014), FICORA is “responsible for the coordination of incident response and information security measures for both government institutions and the private sector” (BSA - The Software Alliance, 2015). Section 304 of the same act lays down the special duties of the authority which are, among others, to “collect information on violations of and threats to information security […] as well as on defects and interference situations in communications networks and services” and to “disseminate information security matters as well as communications network and service matters” (Ministry of Transport and Communications, Finland, 2014).  The Communications Regulatory Authority of the Republic of Lithuania was “established under the Law on Telecommunications and the provisions of the European Union Directives” (RTT, 2015) and “is an independent institution which, among other tasks, is responsible for the regulation of cyber security activities”.  Another case of traditional national regulation is the case of Estonia’s “security measures for information systems of vital services and related information assets” (Estonian Ministry of Interior, 2013) based on the Emergency Act of 2009 (Estonian Ministry of Interior, 2009). The Estonian government requires providers of vital services to report “any security incidents with significant impact” to the Estonian Information System's Authority. In addition, this regulation stipulates that the Estonian Information System's Authority will distribute the information to the institution in charge of this vital service and vice versa.  Germany has also recently put in place local regulation in the field of incident reporting. In February 2015 the German parliament voted a law to improve IT systems safety (German Parliament, 2015). According to this law, all CIIP organisations are obliged to report serious incidents to the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik, BSI).  INCIBE, the Spanish national CSIRT, helped in modifying the ‘Second Final Provision 9/2014’ Telecommunications Law. This amendment obliges Spanish Internet Service Providers and administrators from the telecommunications sector to report and liaise with the competent CSIRT in case of cyber incidents.  In France the Law on Military Programing (Loi de Programmation Militaire (Legifrance, 2013)) requires the Operators of Vital Importance (OVIs) to inform the National Agency for Information Systems Security (ANSSI) on incidents that could endanger the functioning of respective IT system. The OVIs can be part of several sectors, such as the health, water, energy, telecommunication, transportation and finance sectors. In this context, several working groups have been set up per sector, in order to define efficient and compatible rules.

text: 6.1.1 Challenges of Traditional Regulation and Approaches to Address Them

text: The examples above show that several EU Member States as well as EEA and EFTA countries have put in place their own legislation to regulate information sharing related to cyber incidents. Based on the interviews that were carried out we understood, that the differences between these national legislations may hinder information sharing between organisations coming from the different countries in scope, if no EU-wide mechanisms are in place. Moreover, based on a number of interviews carried out during this study, as well as the practical experience of the experts who contributed to this analysis, it appears that local regulations imposing data localisation requirements, information storage restrictions, as well as information secrecy and nondisclosure rules are often perceived by the stakeholders affected as considerable obstacles to an efficient information exchange. In addition, certain countries or sectors consider that information sharing on cyber incidents may at the end be interpreted, on the grounds of the local or European regulation, as an anticompetitive behaviour and hence is likely to infringe competition rules. On the other hand, the national laws on personal data protection seem to be one of the biggest barriers in the information sharing process. For example, in several cases the national laws that consider IP addresses as personal data do not allow organisations to exchange this type of information, even if it could be helpful for other companies (ENISA, 2011). To tackle these challenges, many organisations and initiatives engage in discussions with the law makers and regulators to make them aware of the issues encountered and the improvements that could be made. Examples in this direction could for instance be to raise stakeholders’ education on the correct interpretation of the regulations concerned and enhance market (including public sector) awareness of which information sharing practices are actually permitted and which not. These organisations set up working groups and panel discussions; they draft publications, position papers and other materials to highlight the practical advantages of information sharing. An illustrative example in this area is FS-ISAC. Starting originally as a US initiative, FS-ISAC has become global and is now all the more active in EMEA (Continental Europe, Middle East and Africa). This forum works continuously on the review of European regulatory restrictions and legal requirements to enable information exchange in the financial sector at an international level. To meet their objective, FS-ISAC created a working group called the Joint Working Group Initiative (JWGI), which, amongst other activities, is currently compiling an analysis of legal obstacles and regulatory requirements around sharing of threat intelligence in Europe. Part of this effort is also the design of a report to the attention of companies’ management, to explain the positive impact of information exchange for companies. Moreover, a second working group was tasked to create a regional and per-country ‘landscape map’ of national, sector-specific, and regional threat intelligence sharing initiatives and related organisations in Europe to give practitioners a better overview of who is doing what in this area. Another practice was identified in the Czech Republic, where the NSA CZ engages in bilateral and case-bycase discussions with the different Internet Service Providers (ISPs) when it is not allowed to share certain types of information. However it seems that this process is time-consuming and not really transparent to other community members (ISPs) who could probably benefit from this information (e.g. by learning from others’ experiences without necessarily getting hold of confidential or detailed information about an event). Thus, NSA CZ is trying to automate or improve this process. It is expected that with the adoption of the NIS Directive (European Commission, 2013a), notification requirements will be aligned across the EU and also encourage harmonised implementation across the sectors in the scope of the directive. Last but not least, the findings of this stock-taking exercise confirmed that quite a lot of rule-making on information sharing in the area of information security actually stems not only (and not so much) from

text: formal regulation, but from contractual arrangements, bilateral or multilateral agreements and framework contracts governing the provision of a service. A variety of contracts or agreements can be found both in the private and public sector between the parties involved in the provision of these services (e.g. software agreements). In the majority of cases, all these contracts incorporate high-level or detailed provisions on information reporting and information sharing obligations of the said service providers. Non-disclosure agreements are often included in this contractual framework imposing on their parties (service providers or the organisations requesting their services) which type of information (e.g. on a security breach) could be disclosed, to whom and under which circumstances.

text: 6.2 Alternatives Forms of Regulation (Co-regulation and Self-regulation) in Practice

text: Many different alternative regulatory initiatives to enable information sharing exist beyond the realm of traditional regulation in the EU/EEA today. Based on this, one can conclude that organisations tend to initiate information sharing by using a co- or self-regulatory approach, meaning that organisations establish common rules among each other either with or without the intervention of the regulatory bodies.

text: 6.2.1 Co-regulation in Practice

text: Co-regulation differs from self-regulation in that it implies active government involvement and/or legislative backing of the initiative. A common example of a co-regulatory set-up in this area are Information Sharing and Analysis Centres (ISACs). In the Netherlands, ISACs are established by the government’s National Cyber Security Centre (NCSC) on a sector-by-sector basis (Water, Energy, Finance, etc.). The NCSC facilitates ISACs by providing them with a secretariat. ISACs meetings are held six or seven times per year, but some ISACs meet more regularly than others. There are also regular teleconferences, bilateral meetings between ISAC members, information shared via chats or closed channels/email lists. All Information in ISACs is shared on a voluntary basis, but ISAC members are subject to certain rules. In order to become a member of an ISAC, organisations usually need to be accepted by the other members and have to sign an agreement/Memorandum of Understanding (MoU). This agreement/MoU states, for example, that the information shared within the ISAC cannot be shared onwards with other parties. While the contract is not legally enforceable, a violation of it may result in a warning or the organisation being banned from the ISAC. The instruments and regulatory mechanisms used within co-regulatory initiatives are similar to those of self-regulatory initiatives. All ISACs in the Netherlands use the Traffic Light Protocol (TLP) - a mechanism widely used in information sharing communities - to indicate the permitted distribution of information. In addition, some ISACs limit the number of members of the group, in order to build trust, which is considered as crucial to foster information sharing. In the United Kingdom, a very similar set-up exists, organised by the government’s Centre for the 59 60 Protection of National Infrastructure (CPNI). For thirteen different sectors , the CPNI organises Information Exchanges (IEs), along the same lines as the Dutch ISACs. Information exchanges are free to join, but like in ISACs their membership is determined by the existing members. The CPNI typically provides a co-chair and a coordinator to facilitate the meetings of the IEs. Since trust amongst the members is regarded as crucial here as well, identity and employment verification checks are performed on all

text: applicants as well as checks against official records. Member representatives are expected to attend all meetings, and only a limited number of members from the same organisation are usually allowed. In Germany, UP KRITIS is a large co-regulatory initiative in which critical infrastructure organisations participate (both private and public entities). It is organised by the Bundesamt für Sicherheit in der Informationstechnik (BSI) and the Bundesamtes für Bevölkerungsschutz und Katastrophenhilfe (BBK). UP KRITIS facilitates working groups related to a certain sector or subject. Members do not need to be part of a working group to receive information. The working groups can be intra- or cross-sector related. Information that is only related to certain sectors will however not be shared with others (e.g. banking related-information will not be shared with water sector organisations). Within UP KRITIS, information is shared based on the Traffic Light Protocol (TLP) as the information cannot always be made public. Information is shared via emails and standard templates provided by the Federal Office for Information Security (BSI). Other relevant examples were observed during the research at Member State and EU level. We mention some of them in the list below:  The Dutch Telecommunications Act imposes obligations upon network operators when encountering a state of emergency. However, the practical guidelines on how to comply with these obligations are primarily conceived, prepared and decided on by the market stakeholders themselves. This happens in the framework of a permanent group, the (Dutch) National Continuity Telecommunications Forum (NCO-T), whereby operators meet under the auspices of the Ministry of Economic Affairs (Ministerie van Economische Zaken, 2008).  In the UK, the Energy Emergencies Executive Committee Cyber (E3CC) is in an information sharing roundtable of senior information security professionals across UK electricity generation, transmission and distribution operators. The government participates to this initiative through DECC, CPNI and Ofgem. Via individual membership of CiSP and other communications the group shares information on security incidents in the energy sector.  The Austrian Trust Circle (ATC) founded in 2010 is an initiative of CERT.at and the Federal Chancellery. The primary goal is to build confidence between the responsible persons and organisation in individual sectors of strategic infrastructures so as to facilitate the exchange of security - related experience and ensure that swift and joint action will be taken when appropriate.  The National CSIRT of Luxembourg, CIRCL, operates among others the Threat indicators sharing platform for private sector (MISP). They act as a platform for sharing threat indicators within private and public sectors. Their objective is to improve automated detection and response to targeted cyber attacks in Luxembourg and beyond.

text:  In Sweden, several industry stakeholders and the government have launched a public-private initiative named the Forum for information sharing (FIDI) - in several sectors, such as finance and banking, health, energy and others.  The Thematic Network on Critical Energy Infrastructure Protection (TNCEIP) is an initiative of the European Commission, and is assembling European owners and operators of energy infrastructure in the electricity, gas and oil sectors. Members of the initiative meet four times a year and have access to a shared platform to exchange information on cyber incidents, attacks, vulnerabilities and threats relevant to information security.  In Norway, the National Security Authority (NSM) has launched the Warning system for digital infrastructure (Varslingssystem for digital infrastruktur – VDI) which operates a 'sensor network' to detect attempts of hacking against critical infrastructure across sectors. VDI cooperation is largely based on openness and trust between NSM and participating companies and agencies. 68 69  The MELANI (GovCERT.ch) and SwitchCERT are two Swiss CSIRTs. GovCERT.ch is responsible for the safeguard of critical infrastructure in the public administration and finance and banking sectors. SwitchCERT handles security, fraud detection and elimination. Both organisations are mandated ad interim to provide their services for certain sectors also in Liechtenstein.  At the European level, in the context of

text: a Expert Group meets three times a year to discuss about recent incidents, lessons learned and measures that might be taken to prevent incidents ; the Electronic Communications Reference Group (ECRG), being composed of Chief Information Security Officers (CISOs) of the main electronic communications operators that addresses security topics across the broad subject area of electronic communications including security measures, incident reporting and data protection ; the European Public-Private 73 74 Partnership for Resilience (EP3R) - which existed between 2009 and 2013 - to encourage the private sector to share information, discuss good practices to be followed, policies, objectives, measures and other initiatives that could be undertaken to strengthen the robustness of network resilience.

text:  In March 2012, the US Federal Communication Commission (FCC) , working with communications companies including Verizon, Cox, and Comcast, passed a voluntary code that spells out the steps participating Internet Service Providers (ISPs) must take to combat botnets. ISPs agreeing to follow the code must “take meaningful action” in each of the following areas: education, detection, notification, remediation, and collaboration. Those who follow the code are added to a ‘safe list’ maintained by the FCC.

text: 6.2.1.1 Challenges of Co-regulation and Approaches to Address Them

text: Although co-regulatory initiatives like the examples discussed above are increasingly expanding and grow in popularity, they still have to address a number of challenges: lack of, or weak, enforcement and trust, the voluntary nature of membership and, quite often, the voluntary (or not really monitored) nature of information sharing.

text: On the point of enforcement, it seems that the exclusion of a member can be considered as a strong deterrent only if the co-regulatory platform has proved to bring a real added value to their stakeholders to such an extent that stakeholders who are deprived from membership will consider this as a major loss (e.g. loss of or missing access to knowledge, missing networking opportunities, loss of reputation, etc.). As far as trust is concerned, the view of the authors of this report is that there are means the co-regulatory (as well as self-regulatory) schemes could use to inspire confidence to their members in order to exchange information in a meaningful way without causing any prejudice to the wrongful party. Such means can be, for instance: the mandatory application of the Traffic Light Protocol restrictions, the exchange of information that stakeholders may consider as potential harmful only on a non-named basis and through the use of a trusted third party (e.g. the platform’s co-ordinator), the mandatory execution of strict Non- Disclosure Agreements (NDA) which will, in itself, provide sanctions in terms of inappropriate disclosure of information, the creation of temporary, closed sub working groups relying on an infrastructure which prevents the sharing of the information with anybody outside of the closed working group.

text: Regarding the voluntary nature of membership, a point of discussion that seem to raise concerns within such initiatives is how to strike the right balance between limiting the number of participants (in order to always keep information under control) and taking the risk of not including new stakeholders whose contribution might be valid to their organisation. According to statements and proposals of stakeholders who contributed in the study, a collective design of a Memorandum of Undestanding within the group of existing participants could for example identify ways and ideas on how the group could accept new applications for membership whilst motivating new and existing members to effectively share information (e.g. via meetings, group activities, interactive information sessions, organisation of open events with the aim of attracting new members).

text: On the topic of the voluntary information sharing, the day-to-day operations of the co-regulatory (as well as self-regulatory) fora mentioned herein also demonstrate that stakeholders are in practice more comfortable with sharing information if they know that the objective of the information exchange is to enhance market intelligence and disseminate good practices rather than to spot actions of noncompliance, which may lead to reputational damage, court action and so far.

text: In the light of the suggestions made during the survey, it may be worthwhile examining whether the initiatives based on co-regulation could adopt a ‘modus operandi’ that convince their participants that information exchange does not aim at the sanctioning of bad examples and does not to be perceived as a notification strictly speaking (to the regulator or the ‘market’). The members of such initiatives may need

text: to consider their participation in the group as a unique opportunity to learn from the experiences of peers and participate in the shaping of good practice that reflects the same concerns and, ideally, a common approach to risk.

text: In other words according to a number of experts having contributed in this study, it would be more beneficial to try to better incentivise the market in joining the existing co-regulatory initiatives than to take the effort to enact new regulation that would render mandatory the exchange of information. Moreover, the representative cases outlined in this study seem to address the above hurdles - lack of, or weak, enforcement and trust, the voluntary nature of membership and, quite often, the voluntary (or not really monitored) nature of information sharing -via different measures: agreement on ad hoc rules, focusing on trust-building and using the Traffic Light Protocol (TLP) to regulate how information can be disseminated. A number of initiatives have recourse to other mechanisms, such as fostering a continuous working relationship and regular interactions between their participants, encouraging recurrent meetings and mutual help. Interesting to note, however, is the evolution in Germany, where members’ potential reluctance to share information about vulnerabilities may be overcome through the entry into force of traditional regulation. A new law that obliges critical infrastructure providers (CIPs) to report serious incidents to the BSI was established in 2015 (German Parliament, 2015).

text: 6.2.2 Self-regulation in Practice

text: Through our research we found around thirty examples of self-regulatory efforts. These initiatives can be limited to one sector or can operate across sectors and also national borders. A first illustration of a self-regulatory initiative is Spain’s Industrial Cybersecurity Centre (CCI) , an industry-led centre that operates without subsidies, independently and as a non-profit organisation. Its mission is to boost and improve ‘Industrial Cybersecurity’ in Spain and Ibero-America, defining it as "the set of practices, processes and technologies, designed to manage cyber space's risk associated to the management, process, storage and transmission of information used by industrial infrastructures, from the points of view of people, processes and technologies". We found further self-regulatory practices in Poland. The n6 Network Security Incident Exchange is a free platform for collection and transmission of information on threats and incidents. The platforms includes malicious URLs, malware, scanning, IP addresses or the names of malicious software, depending on the availability of specific information. The platform is aimed at the national and private sector. Next to this, the ABUSE Forum is an initiative of NASK and operates within the NASK CERT Polska team. The forum meets quarterly and also maintains closed email list dedicated to sharing of information about threats and incidents. Participants come from many sectors including Internet services, banking and public administrations. Other noteworthy cases of self-regulation are listed below:  The French Club des directeurs de sécurité des entreprises (CDSE) (Chief Security Officers Club) is an organisation established more than 25 years ago to federate security experts' experiences working in the major French companies.

text:  The Spanish Association for the Advancement of Information Security (ISMS Forum Spain) is a nonprofit organisation founded in January 2007 to promote the development, knowledge-sharing and culture of Information Security in Spain and to act for the benefit of the entire sector. It was created with a plural and open vocation, that is set up as a specialised debate forum for companies, public and private organisations, researchers and professionals as a place where to collaborate, share their experiences and know the latest advances and developments with regard to Information Security. The Association activity is carried out from a perspective of transparency, independence, objectivity and a neutral stance.  In Italy, the Associazione italiana esperti in infrastructure critiche (AIIC) (Italian association of critical infrastructure experts) aims at exchanging experiences and knowledge related to critical infrastructure to create an interdisciplinary and inter-sectoral shared approach among experts of different fields. Their goal is to share knowledge about cyber incidents related to CIIP.  In December 2012, Deloitte Belgium initiated the Cyber Threat Intelligence Sharing Research Project (CTISRP) : an initiative bringing together a number of major public and private organisations from across Europe to discuss sharing of cyber threat information between these organisations. The goal was to understand better the benefit of exchanging information on cyber security incidents across countries, sectors, and industries.  The Bulgarian Association of Information Technologies (BAIT) has the mission to protect the general interests of its members by actively working for the establishing of information society in this country, for the development of the Bulgarian ICT industry and of the ICT market in general. Established in 1995, the association registers currently 135 member companies and organisations. The Association includes companies in the trend of hardware, software, system integration, networks, telecommunications, Internet suppliers, etc.  The Information Technology and Information Systems Security Experts Group (DEG) in Latvia is the former LV CSIRT and is composed by IT and systems experts from various organisations in the country. One of the main goals of the group is to facilitate information exchange among members. DEG has created statutes and a code of ethics to rule the information exchanges. In addition, members meet on a monthly basis.

text: The European Financial Institutes - Information Sharing and Analysis Centre (EU FI-ISAC) is a forum consisting of ‘country representatives coming from the financial sector, national CSIRT's (GovCerts) and Law Enforcement Agencies (LEA’s). Other organisations participating in it are: ENISA, Europol, the European Central Bank (ECB), the European Payments Council (EPC) and the European Commission’ (ENISA, n.d.(b)). The members exchange information on vulnerabilities, threats and incidents and are obliged to use the Traffic Light Protocol (TLP), which ensures that sensitive information is shared according to requirements defined by the source individual/organisation. TLP guides the members’ behaviour on how to share information with the entire sector (provided that there is no use of publicly accessible channels).

text: 6.2.2.1 Challenges of Self-regulation and Approaches to Address Them

text: The challenges faced by self-regulatory initiatives are very similar to those faced in co-regulation set-ups: as noted above, one of the main challenges that is inherent to the use of self-regulatory initiatives is that membership, as well as adherence of their members to agree upon rules is entirely voluntary. Especially in the area of cyber security information sharing, this can pose a problem, as companies and governmental actors are hesitant to share information about their vulnerabilities, given that such sharing can lead to reputational loss especially when the information becomes public. A major deterrent to the voluntary sharing of information is a lack of trust between participants in any given sector, especially in a crossborder context. To address this challenge, many of the self-regulatory initiatives this study has identified regularly organise face-to-face meetings to build trust and encourage sharing amongst participants. In addition, most initiatives regulate the use, and onwards distribution, of information shared using the Traffic Light Protocol (TLP). As stated during the interviews performed during this study, the use of TLP in itself can pose issues as well. In cross-border sharing, country-specific legal requirements may still oblige the receiver of information to pass it on, to a regulator or within a sector, effectively overriding the TLP-level attached to it. In addition, members do not always fully understand that TLP aims to clarify how information can be used and disseminated beyond the group. Furthermore, there seem to be various interpretations of AMBER in various information sharing communities. Some CSIRTs for example, may share information labelled as AMBER downwards with their own constituencies while others would not consider their own constituencies as part of their own organisation. Based on some interviews with experts in the topic, it also appears that some sharing schemes seem to take a more open interpretation than others of AMBER data in some cases, which permits information to be shared with responsible, concerned, external organisations and stakeholders on a case-by-case basis. Some CSIRT experts are of the opinion that TLP should be formalised towards becoming an international standard. According to these experts, it would be helpful for national and governmental CSIRTs to negotiate towards a common TLP standard. Towards this end, the challenge is to find all TLP interpretations currently in use by all information sharing communities and to find a representative translation (Millar, 2015). Another concern raised about TLP relates to the fact that more and more CSIRTs are connecting with the intelligence community which is used to employ government classification schemes (such as SECRET and TOP SECRET). However, according to some CSIRT experts, it would be challenging to combine the use of TLP and classic classification. The first reason for this is that not all of the intelligence community is used to the TLP logic. A second reason may be that TLP has no formal legal value thereby possibly disallowing the intelligence community to use it. Another challenge of self-regulation compared to traditional regulation is the lack of mechanisms to enforce agreed upon rules. We found that this can be overcome by warning and excluding members in case of non-compliance to the set rules. In the EU FI-ISAC initiative for instance, members sign up to Membership Guidelines through which they commit, inter alia, to regularly attending physical meetings. Even though there is no legal recourse to non-compliance with this rule, members may get excluded from the initiative and lose the benefits that come with participation if they do not attend three successive meetings.

text: 6.3 Other Approaches (Information and Education) in Practice

text: Our desktop research identified approaches implying awareness raising and education on cyber security and incidents. These approaches do not seem to be defined by either a regulatory body or by a group of organisations. They seem to be voluntary initiatives that have as main objective to disseminate information towards others and to educate the community on the current threats, vulnerabilities and other cyber security related challenges. A first example of this type of approach are the working groups held by the Czech CSIRT (CSIRT.CZ). CSIRT.CZ organises regular meetings with the members of the security community of the Czech Republic. Events are held twice or three times a year. During the meetings, members can discuss topics related to current trends in the field of safety, security threats, and the development of cooperation between security teams. Moreover, the meetings also represent the opportunity to mutually exchange experience in the field of prevention and resolution of security incidents. A second example is the Alliance for Cybersecurity launched by the German BSI and the Federal Association for Information Technology, Telecommunications and New Media. This cross-sector and voluntary initiative aims to ‘inform and report on cyber incidents’ at national level (Jones Day, 2014). The objective of this organisation is to share information related to cyber security and incidents to help the community in being prepared to encounter them. A third example, the Cyber-security Information Sharing Partnership (CiSP) in the United Kingdom is also a representative example of the awareness raising approach. This cross-sector initiative launched by CERT- UK has the objective to ‘share cyber threat and vulnerability information in order to increase overall situational awareness of the cyber threat and therefore reduce the impact on UK business’ (CERT-UK, n.d.). Information can be exchanged among members but they also receive reports from the CERT-UK concerning the current situation of the network. Moreover, the initiative has been extended to the Northern Ireland region (Northern Ireland CiSP) since January 2015. The goal of this regional community is to share information with local members on cyber security threats. Another example is the Belgian Network and Information Security (BELNIS) , established in 2005, which acts as a coordinating workgroup that includes representatives from government agencies engaged in cyber security. It provides advice to the government on cyber security incidents and cyber security in general. Other relevant examples that came up during this study are listed below.  In Slovakia, the Slovak Office for Personal Data Protection started to publish information on the official website (as reports, guides, magazines and in other formats) to organise events (seminars, conferences) or propose advisory services related to the issue. The Office collaborated in that regard with companies from the IT sector and other public and private institutions (FRALEX, 2009).

text:  The National Security Authority of Hungary organises a yearly ‘Conference on Information Security and Cyber Defence (ISCD)’. Started in 2011, this conference aims at exchanging information related notably to security and cyber defence, cyber challenges and cyber threats.  The (ISC)² Ireland Chapter is an organisation that aims at raising awareness and educating the Irish community by organising seminars. Their goal is to share information and knowledge and market collaboration.  The Cyber Security Research Center from Romania (CCSIR) is a non-governmental organisation with the objective to promote and support research related to cyber security in Romania and encourage market partnerships in this area.  Under the Commission’s Safer Internet Action Plan (2004), the Safer Internet Forum was established to act as ‘a discussion forum including representatives of industry, law enforcement authorities, policymakers and user organisations (e.g. parent and teacher organisations, child protection groups, consumer protection bodies and civil and digital rights organisations). It provides a platform for national co-regulatory or self-regulatory bodies to exchange experience and an opportunity to discuss ways in which industry can contribute to the fight against illegal content (European Parliament and the Council, 2015).  The European Cyber Security Protection Alliance (CYSPA) focuses on a sector-by-sector approach to evaluate the impact of cyber risks and to create a community of stakeholders interested in sharing knowledge to improve their level of cyber protection.  Based on existing industry standards, guidelines and practices, the US National Institute for Standards and Technology (NIST) issued the first version of the NIST Framework for Improving Critical Infrastructure Cybersecurity in 2014. The Framework only intends to promote the protection of critical infrastructure and can be used as a handbook by operators across sectors and borders. With the goal of educating and sharing information with the community, ENISA issues many reports and often organises workshops or exercises. Noteworthy cases are the guidelines for CSIRTs collaboration (ENISA, 2009), studies to encourage exchange between CSIRTs (ENISA, 2011) or to present the advantages of information sharing (ENISA, 2010).

text: 6.3.1 Challenges of Information and Education and Approaches to Address Them

text: In the light of the interviews conducted, it appears that the trust element is equally important in this stream as in the co- and self-regulatory set-ups. The measure of “success” of education and similar

text: approaches largely depends on how eager the members are to share information and be transparent regarding their needs, the practices they follow (e.g. in case of a cyber incident) and the experiences they have. As the primary objective of this type of information sharing initiative is to reach and educate as many members as possible, trust building might be difficult to achieve among large groups of people/participants. In particular, interviewees noted that members might hesitate to exchange information when they are not acquainted with most participants. However, the example of the Cyber-security Information Sharing Partnership (CiSP) shows how this challenge may be addressed by insisting on the fact that the applications to become a member are “assessed fairly and independently” (CERT-UK, n.d.). In this case, the organisation assures the members that the used information sharing platform is secure, frequently monitored and tested. Furthermore, based on the literature reviewed during this study, other challenges and the appropriate measures to address them may be highlighted in this type of approach. Firstly, it might be challenging if the objective of the community is opposed to, or not in line with, the goal of another regulatory instrument. In this case, the initiative should be incorporated or aligned with the other policy tools. Secondly, it might be hard to measure and to verify whether the behaviour of the community has changed or the degree at which the awareness has been raised as a result of an initiative under this cluster. Moreover, it might take time to meet the objectives of this approach (i.e. education and awareness raising) as the goal is to reach a wide community. Therefore, this type of tool should be used in situations where there is enough time to diffuse the message and to evaluate the results of the initiative (OECD, n.d.).

text: 7 Conclusions and Recommendations

text: 7.1 Conclusions

text: This report aims at identifying the regulatory and non-regulatory approaches that EU Member States as well as EEA and EFTA countries use, in order to share information on cyber incidents and to address the challenges of sharing information. Based on desk research and the conduct of interviews, and with the support of the of National Liaison Officers (NLOs) of ENISA, more than eighty (80) initiatives and organisations and more than fifty (50) national and governmental CSIRTs involved in information exchange on cyber incidents were identified at EU and EEA level. More information on this list of identified initiatives and relevant organisations (including national and governmental CSIRTs) as well as on the possible access to it can be requested by contacting cert-relations@enisa.europa.eu. Some of these initiatives have been discussed in this study based on the distinction between three different clusters of regulatory/non-regulatory approaches, being: 1) traditional regulation; 2) alternative forms to regulation, such as co- and self-regulation; and 3) other approaches, such as information and education.

text: 7.1.1 Geographical Distribution of Initiatives

text: In light of our findings, we understand that there are countries - such as for example the Netherlands and the United Kingdom - where the co-regulation approach is used the most. This is mainly due to the relatively high number of ISACs (Information Sharing and Analysis Centres) and/or IEs (Information Exchanges) that exist in these countries. Examples of self-regulation can be found in Poland and Spain. Furthermore, at EU and global level, the co- and self-regulatory approaches are preferred to share information or launch new initiatives. Besides the Netherlands and the United Kingdom, a relatively high number of initiatives exist in France. These initiatives are usually based on other non-regulatory approaches, such information and education schemes. Furthermore traditional regulation does not seem to be the most used approach among the countries in scope, but the use of this approach is spread geographically across EU, EEA and EFTA. Finally, some countries have less information sharing initiatives or do not run them by themselves. Some countries join forces with larger countries: a recent illustration of this is the case of Liechtenstein which mandated the Swiss CSIRTs – MELANI and SwitchCERT – to provide ad interim their services for certain sectors in Liechtenstein too.

text: 7.1.2 Prevalence of Alternative Types of Regulatory Initiatives

text: Although national legislators in EU Member States seem to increasingly issue traditional regulation in the cyber security space, most information sharing initiatives identified in this study are still based on self- or co-regulation. In addition, traditional regulation, triggered especially from European legislative texts which aim at harmonising notification requirements, has so far not moved beyond imposing incident reporting obligations on electronic communications and critical service providers. Although other sector communities will be concerned in the near future by notification obligations that are foreseen in European legislation that is currently in preparation (see the upcoming NIS directive for example), this extension will not change the fact that regulation is perceived by the market as a ‘one-way street’ since information sharing is actually ‘directed’ without necessarily implying the real involvement of the wider cyber security community.

text: Based on desk research and the interviews conducted, we understood that most initiatives do not only share information on cyber incidents. Their missions and objectives seem to be broader than just concentrating on this type of events. For example, besides incidents, vulnerabilities and threats, organisations are willing to share information such as strategies related to cyber security, operational methods and best practices in the information security area. It appears that a substantial part of the information is shared across sectors, this means that organisations coming from different sectors are part of the same group and share with other members, regardless of their sector. However, this trend seems to change with the level of maturity of the initiative and of the sector. The finance and banking sector and the public administration sector seem also more developed in terms of intra-sector information exchange. The initiatives appear to be relatively open to welcoming new members. Only few organisations follow strict entry criteria or request a membership fee. Finally, when the initiative does not stem from traditional regulation, the information is in many cases shared on a voluntary basis. In the majority of cases information is exchanged informally (e.g. during face-to-face meetings, conferences, etc.), as well as virtually (via platforms, email lists, teleconferences, etc.).

text: 7.1.3 Challenges to Sharing Information on Cyber Incidents

text: Different regulatory and non-regulatory approaches bring different challenges with them. In the case of traditional regulation, we understood that legislation related to mandatory reporting varies from Member State to Member State and is sometimes vague. It is however expected that recentlyenacted European regulation (e.g. the eIDAS Regulation) and other acts being currently shaped (e.g., proposed NIS Directive (European Commission, 2013a)) will streamline notification requirements crossborder and will promote harmonisation of the practices that have already been deployed at national level around security breach reporting, cyber incident preparedness and reaction. Consequently, organisations do not know exactly what they need to share. Conversely, in voluntary information sharing initiatives, some members may hesitate to share personal or internal information with other members. In the case of educational or awareness raising approaches, as the primary objective of this type of information sharing initiative is to reach and educate as many members as possible, trust building might be difficult to achieve among large groups of people. As a result, members might hesitate to exchange information when they are not acquainted with most participants.

text: 7.1.4 Trust as a Key Element for Information Sharing

text: As many other studies pointed out, trust is a key success factor for information exchange in the field of cyber security and incidents. Members of a community want to know with whom they share data and whether the data will be handled appropriately. Throughout the interviews that were carried out, we understood that trust building has become one of the main objectives of the initiatives as it facilitates the exchanges, especially when the initiatives are based on voluntary information sharing. In this context, trust building seems to be a process where participants need to prove that they can be trusted and that they share the same objectives, ethical principles, and views of their counterparts. It must be noted that the dialogue and information sharing within the co- and self-regulatory schemes discussed herein does not primarily aim at revealing stakeholders’ weaknesses or gaps in terms of cyber security but rather to create a climate of confidence and trust to share between the stakeholders concerned good and bad practices, exchange experiences around events, discuss preparedness measures and even reactions from citizens or regulators in the information security broad subject area. Along these lines, it is noteworthy to state that the climate of trust is built more easily when the purpose of the information

text: exchange is ‘intelligence’ (communicate knowledge and best practices) rather than ‘evidence’ (use information as proof in order to take action before a regulator or court). Ideally, the success of the co- or self-regulatory approach is not only to bring forward rules made by the market but also create a trusted environment which will encourage awareness raising and participants’ education. Interviews suggested several methods to build trust: informal meetings, small group meetings, transparency, teleconferences, use of TLP or of other standards establishing some rules on how information should be communicated.

text: 7.1.5 Important role of National and Governmental CSIRTs

text: In the context of the information sharing initiatives, it is worth mentioning the important role of national and governmental CSIRTs that was already presented for instance in the study ‘A flair for sharing – encouraging information exchange between CERTs’ (ENISA, 2011). It seems that certain CSIRTs have launched activities to promote information exchange among their constituents. Noteworthy cases are: INCIBE-CERT (Spain) which took actively part in the change of the national regulatory framework on incident reporting and, based on this regulatory change, it follows a collaborative approach towards sharing useful information with Internet Service Providers (ISPs) and the private sector in general; the NASK Polska team which launched the ABUSE Forum, being a cross-sector initiative to share information on cyber security incidents and threats amongst ISPs, financial operators and the public sector; the Luxembourg CSIRT running, amongst others, the threat indicators sharing platform aiming at improving the public and private sectors’ response to cyber attacks within the country and beyond; or the Czech CSIRT.CZ organising working group meetings for security teams. By developing these activities, CSIRTs contribute and share their experience with other organisations willing to exchange information. They can share best practices and potentially serve as examples for future initiatives.

text: 7.2 Recommendations

text: In the light of the practices discussed in this report and the conclusions above, the following recommendations may be considered as follow-up steps to this study. Where possible, tentative action owners are proposed. Accordingly, the relevant communities to take certain action in order to enhance the landscape of information sharing are primarily: law makers and regulators, governmental institutions; the owners, founders, initiators or co-ordinators of the different initiatives discussed herein (collectively named sometimes here as ‘initiatives’ or ‘approaches’); the market stakeholders in general or a specific community, as well as European bodies such as ENISA.

text: 7.2.1 Leverage Existing Self-Regulatory and Co-regulatory Initiatives

text: A number of areas for improvement can be suggested in order to fully benefit from the co- and selfregulatory schemes, in particular trust, enforcement, as well as transparency and promotion. In a nutshell, following challenges and areas of improvement have been identified based on the findings of this study:  Trust: To foster trust, information sharing founders, coordinators and/or facilitators could use following alternatives:

text: 1) limit the number of participants to better control the channels and boundaries of information exchange;

text: 2) use the Traffic Light Protocol to regulate information sharing and ensure that members are aware of how to use it in practice; and

text: 3) set rules (and adequate mechanism to enforce them) to prevent absenteeism and to further encourage regular information sharing by each member.

text:  Enforcement: Voluntary approaches naturally suffer from the lack of legal basis and strict enforceability of any agreed upon rules. To overcome this challenge, the initiatives should build up sets of rules and exclude members who do not adhere to the rules of the initiative.

text:  Transparency and promotion: For co- and self-regulatory initiatives to grow efficiently, it is essential to clearly inform the participants of the relevance and real added-value of such initiatives as well as to be transparent regarding the rules and practices followed. These initiatives (if necessary, with the backing of the competent authorities overseeing them) should emphasise more dynamically the assets and benefits that members of such initiatives will draw by their active participation in such fora. The founders or facilitators of the co- or self-regulatory groups such as the ones identified in this study, should ideally design a ‘go to market’ plan to better highlight to their members and potential joiners the advantages, added-value elements and the incentives of participating in the group.

text: For law makers and regulators or any other stakeholder willing to launch new programs or initiatives for strengthening information exchange, it is highly recommended to look first at the lessons learned and the experiences gained within the currently existing initiatives and then leverage on the existing successful initiatives. It may be more worthwhile and cost effective to first check to what extent the current initiatives can be complemented rather than spending additional effort (operational, financial and technical means) to launch new initiatives.

text: Recommendation for:

text:  EU and national policy makers, law makers and regulators;  Governmental institutions and administrative bodies as they have an influence and control on the policy and legislative framework; and  The actors of the initiatives as such, being indicatively the initiatives’ founding or supporting bodies being CSIRTs or other.

text: 7.2.2 Harmonise Regulation Rather than Enact New Mandatory Rules

text: Traditional regulation related to cyber incidents reporting does not seem to be harmonised at EU level and remains a vague notion in certain Member States. This might be confusing for organisations willing to share information and can, in some cases, hinder information exchange. Member States law makers and regulators should therefore be more precise in terms of what is allowed or must be reported; they should clearly define the situations in which mandatory reporting is needed or what constitutes personal data. Moreover, they should establish laws and guidance to the attention of stakeholders involved in information sharing initiatives, in order to orientate them on how to minimise the exchange of personal information or on how to share this kind of data in case of real necessity. With the adoption of the NIS Directive, cyber security might be at the centre of discussions in the EU, therefore, law makers and regulators or other interested stakeholders should take this recommendation into account when implementing mandatory reporting rules at EU level. Regulatory bodies could also provide guidelines with the purpose to harmonise the different notification requirements established by the eIDAS Regulation, the Personal Data Regulation and the proposed NIS Directive. Finally, public administrations should take actions and be involved in the field of information sharing as they have an important influence on the legislative framework of law makers and regulators and their behaviours.

text: Recommendation for:

text:  European oversight and regulatory bodies, competent by sector;  European policy and law makers;  National regulatory and oversight bodies; and  Standard-setting bodies.

text: 7.2.3 Further Develop Intra- and Cross-sector Exchange with Government Intervention

text: As intra-sector information exchange seems to be more developed under the co-regulation approach (e.g. ISACs in the Netherlands or IE’s in UK), national governments should back up and help national initiatives to develop themselves, to become more mature and increase the number of exchanges. Governments and information sharing initiatives facilitators can use different approaches and solutions to encourage organisations to share information (mutual contracts or agreements, terms and conditions to sign, protocols, secretary support, etc.). Recommendation for:

text:  National governmental institutions; and  Information sharing initiatives’ facilitators (e.g. CSIRTs or administrative body supporting an initiative financially or in another way).

text: 7.2.4 Take Advantage of the Practice Developed by National and Governmental CSIRTs

text: As CSIRTs seem to be experienced in information sharing, the governments, information sharing facilitators or any other stakeholder willing to engage in a new initiative should base themselves on the examples of

text: and on the lessons learnt from CSIRTs. CSIRTs could also be involved by facilitators in more information sharing initiatives so that they can actively share information, best practices and knowledge with other organisations. Recommendation for:

text:  National governmental institutions;  Information sharing facilitators with the support of CSIRTs; and  Any stakeholder willing to engage in a new information sharing initiative.

text: 7.2.5 Build upon Existing Work Performed by EU Institutions and Bodies – including ENISA – and by the Member States in the Field of Information Sharing on Cyber Security Incidents

text: A number of examples outlined in this study have shown that initiatives active in the area of critical infrastructure protection can already demonstrate a good record of information sharing. On top of that, mandatory European regulation related to incident reporting that is already enforceable in the electronic communications sector incite the relevant operators to adopt a ‘culture of sharing’ (towards the regulators but also towards their peers and the public at large). The national and European regulatory bodies in these areas could help build upon the best practices followed by the market in incident reporting and, based on the practical experience gathered, back the initiatives identified herein and, to a certain extent, help disseminate to the market good examples, tools and, at the end, a modus operandi on information sharing. Along the same lines, being the European Union Agency for Network and Information Security ENISA gained a long and deep experience in the field of this study. Several initiatives of information sharing have been launched by ENISA related to notification requirements and electronic communications network resilience, many ideas and propositions have been sketched and good practices have already been produced related to information sharing. The European Commission and ENISA should find ways to boost the interactive dissemination of the knowledge that have already been produced by identifying the appropriate channels to distribute this know-how to the appropriate communities and reach the initiatives identified here and the stakeholders of them. Last but not least and according to ENISA’s Work Programme, the goal of supporting CSIRTs in the area of information security could take a concrete dimension if ENISA helps these organisations in the information sharing initiatives they take or may plan to take in the future. Such a supporting role could specifically take the form of, indicatively: 1) creation of CSIRTs working group that will tackle the matters of incident reporting and information sharing; 2) awareness raising, for example by the organisation of educational and training events around information sharing within the CSIRTs community; 3) dissemination of good practice on information sharing; 4) support the CSIRTs practically in the design of tools necessary to enhance the communication of information and transparency towards the stakeholder communities having to cooperate with the CSIRTs (model cyber-threat/cyber-incident notification forms, sample confidentiality/Non-Disclosure Agreements – NDAs, etc.). A first step towards this direction could notably be the elaboration of a more in-depth study aiming at assessing the way of functioning, current results and working programmes of national and cross-border information sharing initiatives starting with the ones identified here. In tandem, or as next step, ENISA

text: could envisage the launch of a project or initiative (in partnership with CSIRTs but also with other expert groups and market stakeholders) to build upon existing working tools related to information exchange (membership forms, contracts, NDAs, virtual tools, etc.) or to initiate work in this direction (as per point number 3) above). The output of such work could consequently benefit not only the CSIRT community but any initiatives, especially the less mature ones, in the information exchange and information sharing area. On the other hand, public administrations and regulatory bodies should build upon the work produced in the field by EU institutions and bodies – including ENISA – and by the Member States, and leverage it while taking into account the national specificities, stakeholders’ experiences, as well as the existence and performance of initiatives in their respective countries.

text: Recommendations for:

text:  EU and national policy makers (including administrative institutions as they have an influence and control on the policy and legislative framework of the law makers and regulators’ behaviour);  Regulatory and oversight bodies; and  European Commission (e.g. DG Communications Networks, Content and Technology (DG CONNECT), DG Research and Innovation (DG RTD)) and ENISA as far it concerns to find ways to boost the interactive dissemination of the knowledge and good practices.

text: 7.2.6 Encourage Cross-border Cooperation and Build Joint Initiatives at EU level without excluding an international reach whenever possible

text: The desk research and interviews conducted throughout this study have demonstrated that similar information sharing initiatives exist in several Member States. Dutch ISACs and UK IEs, or the Spanish Foro ABUSES and the Polish ABUSE Forum are noteworthy cases. Member States and their respective organisations which have supported the set-up of the initiatives discussed herein (as well as the ones that may be in their infancy now in some Member States or the ones which will emerge in the future), such as CSIRTs, shall expand the competence of those initiatives, as well as procure them with the necessary financial and funding means, to liaise with their counter-parts crossborder, extend their memberships beyond the national borders and attract multinational participants (e.g. global corporations). Furthermore it appears that it would be more beneficial for organisations having a global footprint to engage in information sharing initiatives at international level instead of spreading funds, time and effort on many geographically dispersed and different local initiatives. The exchange of knowledge, good practices and experience amongst the initiatives across borders could enhance information sharing in the cyber security area and create the foundations of pan-European or international information exchange schemes. An interesting example for consideration will be the launch of the Connecting Europe Facility (CEF) Core Cooperation Platform / Core Service Platform for CSIRTs that is envisaged by the European Commission (DG CONNECT). Another illustration is represented by the cyber-related Coordinated and Support Actions

text: foreseen under the Horizon 2020 work programmes by the European Commission (DG Research & Innovation). Recommendation for:

text:  Member States;  European Commission (e.g. DG Communications Networks, Content and Technology (DG CONNECT), DG Research and Innovation (DG RTD), DG Internal Market, Industry, Entrepreneurship and SMEs (DG GROW), DG Migration and Home Affairs (DG HOME), DG Joint Research Centre (DG JRC) and DG Energy (DG ENER));  ENISA; and  Current and future initiators, founders and facilitators of initiatives.
