text: Executive summary

text: Since 2011, the plenary sessions of EP3R addressed a number of topics ranging from Trusted Information Sharing, Incidents Preparedness and Management, Mutual Aid Assistance and the Protection of Critical Information Infrastructure. As EP3R discussions progressed, participants realised gradually that many concepts and terms were not clearly defined. During Summer 2012, the EP3R constituency devised a number of Work Objectives, and the initial Working Group 1 on Key Assets Categorisation led to the Creation of two Task Forces to issue a proposal for a methodology. The two topics addressed would be “Terminology Definitions” on one hand, and “Categorisation of Assets” on the other hand. Since a common terminology is the base of the characterisation of assets, it was later decided to use the latter to initiate the first. Both Task Forces were given 3 months to reach a conclusion on both topics. A few teleconferences and individual contributions helped to build this document. Together, the efforts of these two different task forces also represent the starting point for future efforts to secure and improve resilience in Europe’s cross-border and cross-organization context. Another important trait of these two task forces with the other EP3R position papers is the use of the Mutual Aid for Resilient Infrastructure In Europe (MARIE) ingredients in order to offer to all the interested stakeholders a comprehensive and articulated approach for cooperation and collaboration. The work produced by both Task Forces includes: - A list of commonly accepted Terminology sources; (see Annex A) - A proposal to categorise Terminology definitions according to their context; (Annex C) - An initial devise of key terms, those initially necessary to all Task Forces and further EP3R works; (Chapter 2.4) - An ontology for categorisation of assets and future development of Terminology Definitions; (Chapter 3.2)

text: As a common approach to subsequent activities (such as Risk Management, Business Continuity Management, etc). The Task Force recommends the pragmatic adoption of the 8 Ingredients devised in the M.A.R.I.E. (Mutual Aid for Resilient Infrastructure in Europe) as root Categories for Key ICT Assets. Should other sectors be later considered, a similar ontology could be developed where needed. Those recommendations were intended for EP3R, but however are valid for any Public-Private Partnership including EP3R’s successor, the NIS Platform.

text: 1 Introduction

text: This Position Paper intends to establish the foundations of a commonly accepted and adopted methodology to define proper Terminology within EP3R, and later allow a concise Key Assets Categorisation. Such a Position Paper was intentionally kept small so it could be easily communicated and shared among EP3R participants to foster common understanding in a fast and effective way. The principle adopted within EP3R was that each Task Force would establish their own specific Terminology whenever required, and use this approach as a principle.

text: Goal

text: The purpose of inventorying Terminology sources was initially to ensure that all Participants could work on the same grounds, and allow discussions to be cleared from any misunderstanding.

text: Target audience

text: This Position Paper is addressed to all EP3R participants and the NIS Platform Working Groups. The methodology used in these task forces is similar to previous EP3R efforts. Several seasoned industry experts from different organization and backgrounds provided their expertise and advice in the definition of the contents. Following to on-site meetings and the desktop research, some individual feedback and recommendations where provided and used to integrate the materials collaboratively exchanged and produced via email and during the open teleconferences. The contents and participation to these task forces was renewed in two different occasions and cover a wide spectrum of expertise and different type of organizations and backgrounds. These initial efforts lasted two months during Spring 2013.

text: Terminology Definitions

text: During the early stages of work in the EP3R working groups, Participants have many times reported that several words were lacking a clear definition and also a common understanding. As a consequence, discussions were hanging on details to clarify, instead of allowing a seemless and fluid debate. The EP3R Working Group 1 on Key Assets therefore recommended that a Glossary is collegially adopted by EP3R constituency as a reference for further works. For these reasons the scope of the Task Force was focused on: - Taking stock of existing Terminology definitions available freely (to avoid licencing issues); - Identifying commonly used terms in the CIIP sector; - Providing or reuse (where possible) for each term a simple and effective definition, avoiding controversial definitions as much as possible. - Using free sources for such definitions where available to build up their recommendations, or get authorisation from relevant author(s).

text: The Deliverable of the TF was defined as follows in the EP3R Work Objectives: - A list of Terms commonly used in the CIIP Industry;

text: Assets Categorisation

text: A risk assessment of the protection level of Critical Information Infrastructures depends initially on a comprehensive inventory of all the components which constitute them. These are generally referred to as “assets” and comprise equally physical and technical assets, facilities, but also resources (e.g. supply chain), functions (i.e. Human operations), and regulatory environment (e.g. Policies, Standards, etc). A proper risk analysis approach would take into consideration any ingredient of the resulting service operated, and assess each asset category’s risk occurrence and likelihood. Since EP3R focuses on the proper operations of Critical Information Infrastructures (and unlike the Art.13a regulation *not* on the services), the actual operations of the CII are under the initial scope of reflection. The Task force was requested to undertake all necessary actions to define a proper and useful approach to the usage of CII stakeholders to ensure all Critical Assets supporting CIIs are encompassed in risk analysis, business continuity planning and disaster recovery exercises, hence ensuring proper preparedness and response capability for disasters or incidents. This requirement arose following the presentation during an EP3R Plenary Session (December 2011) of a major Telecom Operator’s Risk Management methodology.

text: Among the activities undertaken, the following have been considered:

text: - Taking stock on current practices in place in Member States for defining NCIs; - Taking stock on Industry’s Risk Identification and Risk Management good practices; - Evaluating the setup a reference framework and initiate a research activity on the methodology for the identification of ECIIs. “Functional” supply chains could be identified together with connections/ interconnections. - Convergence to a final, simple result.

text: The Deliverable of the TF was defined as follows in the EP3R Work Objectives: - A taxonomy of typical components which constitute a Critical Information Infrastructure. - From the various methodologies proposed, select the parts relevant to Critical Information Infrastructures Protection, and establish a formal recommendation for a set of criteria allowing “Key Assets Identification”.

text: 2 Adoption of Terminology Sources 2.1 Key Terminology

text: During the discussions of the Task force it was decided to start addressing the issue using a taxonomy approach. Due the short timeframe and the voluntary basis involvement it was considered difficult to produce a comprehensive glossary covering all the possible terms. Therefore the TF decided to give a clear and unique definition only of the most important concepts that represent the foundations of all EP3R efforts. ICANN The result is close to 160 definitions gathered • Bylaws for Internet Corporation for Assigned Names and Numbers from free access sources, properly referenced, IETF and some definitions developed by the TF • Internet Engineering Task Force - RFC 4949 members themselves when the existing ones ISACA were not satisfactory. • Control Objectives for Information and Related Technology (COBIT) ISO/IEC For the broader glossary it was preferred to • 27000 series - Information technology — Security techniques — Information security define a first list of most common term and for management systems — Overview and vocabulary. ITGI those not covered use taxonomy to • IT Control Objectives for Sarbanes-Oxley characterize the most important clusters and NATO bound them with the most relevant references • AAP-6, NATO Glossary of terms and definitions present in literature. IARU The following definitions were identified, • The Tampere Convention adopted by the Task Force, and used as United Kingdom's Cabinet Office foundation for all discussions relating to • Information Technology Infrastructure Library (ITIL) Critical Information Infrastructures.

text: 3 Assets Categorisation Principles 3.1 Introduction

text: Since the beginnings of EP3R, the Assets Categorization Task Force has discussed several approaches on how to address the most important issues and which best practises to consider. During the teleconferences several methods have been discussed in order to create an initial risk mapping ontology in order to follow the path traced by existing literature regarding CI. Existing experiences 3 4 like the one in Finland and UK were cited as possible examples to refer to. The initial idea was to focus on public networks and align the work with the Art 13a content, which is the obligation for the Telecom Operators to report incidents. Therefore it was decided to proceed initially with definitions of Critical Infrastructure / Critical Information Infrastructure / European Critical Infrastructure. Moreover the different business models that can be applied in the Telco sector (fixed/mobile/connectivity provider) were emphasised and also the consequent different definitions of criticality.

text: 3.2 Initial Ontology

text: During the initial open teleconferences the task force decided to tackle the problem starting from the differences between Internet Exchanges points (IXs) and manufacturers methodologies: IXs are more focused on the physical and supply chain and the data/control plane repercussions, while Manufacturers will concentrate on the meta-classification of specific assets. Moreover the different business models that can be applied in the Telco sector (fixed/mobile/connectivity provider) were emphasised and also the consequent different definitions of criticality.

text: In the course of the proceedings and discussions with the experts it was decided to use primarily the Mutual Aid for Resilient Infrastructure in Europe (MARIE) eight ingredients to align the output with the other task forces.

text: This effort helps to draw a red line between the different goals and have a more holistic approach. In the presented table the effort of the TF are sketched in order to give the an overview of the possible different aspects that must be addressed. The following ontology should therefore be viewed as a means of gaining a foothold in an extensive, dynamic subject rather than as a statement of universally accepted fact.

text: Page 9

text: EP3R 2013 – Position Paper

text: In the presented table the effort of the TF are sketched in order to give the an overview of the possible different aspects that must be addressed

text: The idea was to identify generic high level critical component that can be, once the ontology is released, tailored due to the specific business model and size of the organization.

text: Thus by using the Mutual Aid for Resilient Infrastructure In Europe (MARIE) eight ingredients this could be also connected with all the related literature and efforts and allow the interested parties to foster collaboration based on the same terminology baseline. For this reason also the terminology definition approach that follows makes use of the same categorisation.

text: The figure below shows a initial proposal classification of activities, assets and paves the way for Terminology categorisation and development as well.

text: EP3R 2013 – Position Paper

text: 4 Conclusion

text: This work was intended to be a very first step within EP3R that could be a foundation for later developments. The Task Forces ran for two months, just before the EP3R was subsumed to the NIS Platform. This was actually the first attempt within the European Public Private Partnership for Resilience to reach convergence points in Participants’ understanding, and allow to prevent many misunderstandings as they used to happen in the past. The Task Force acknowledges that this iteration solely addresses the Telecom Sector, and suggests that it should be expanded to Sectors which depend on ICT, such as Health, Finance, Transports, Energy. But also, such definitions might be also needed for the specifics of CyberSecurity areas: Botnets, Cyber Police, etc. The process for each Sector should be similar, i.e. the identification of Terminology Sources relevant to the Sector considered, submitting a consolidated listing of terms to a panel of Experts, and their formal adoption of one definition per term. Among the important uses of Terminology Definitions, the Task Force felt that Mutual Aid Assistance was probably the most crucial, since all participants in the Agreement need to speak the same language. Some specifics of Mutual Aid Assistance should therefore be explored and a proper list of defined terms adopted. In the Working Groups meeting of the NIS Platform, a few participants raised the need for starting a similar initiative. EP3R therefore hands over its initial conclusions so their starting point is already more advanced than for EP3R, 4 years ago.
