Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for

20、 Advanced Networking (TISPAN). Introduction The present document is one of a set of documents that addresses standardization of security protocols and mechanisms within the context of the eEurope 2005 programme. The suite of documents in this suite is composed as follows: EG 202 387: “Telecommunicat

21、ions and Internet converged Services and Protocols for Advanced Networking (TISPAN); Security Design Guide; Method for application of Common Criteria to ETSI deliverables“. ES 202 383: “Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Security Design

22、 Guide; Method and proforma for defining Security Targets“. ES 202 382: “Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Security Design Guide; Method and proforma for defining Protection Profiles“. TS 102 165-1: “Telecommunications and Internet con

TS 102 165-2: “Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Protocol Framework Definition

24、; Methods and Protocols for Security; Part 2: Counter Measures“. DTS/TISPAN-07008-Tech: “Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); Protocol Framework Definition; Protection Profile“. EG 202 549: “Telecommunications and Internet converged Servi

25、ces and Protocols for Advanced Networking (TISPAN); Design Guide; Application of security countermeasures to service capabilities“. These documents are developed based on the objectives of the eEurope programme and are also developed to ensure they comply with the overall objectives of the European

26、regulatory framework as defined in the following documents: Directive 2002/19/EC of the European Parliament and of the council of 7 March 2002 on access to, and interconnection of, electronic communications networks and associated facilities (Access Directive). Directive 2002/20/EC of the European P

27、arliament and of the council of 7 March 2002 on the authorisation of electronic communications networks and services (Authorisation Directive). Directive 2002/21/EC of the European Parliament and of the council of 7 March 2002 on a common regulatory framework for electronic communications networks a

28、nd services (Framework Directive). Directive 2002/22/EC of the European Parliament and of the council of 7 March 2002 on universal service and users rights relating to electronic communications networks and services (Universal Service Directive). ETSI ETSI EG 202 549 V1.1.1 (2006-12) 6 Directive 200

29、2/58/EC of the European Parliament and of the council of 12 July 2002 concerning the processing of personal data and the protection of privacy in the electronic communications sector (Directive on privacy and electronic communications). In particular the present document forms part of the standardiz

30、ation initiative for the Next Generation Network (NGN) platform to be used in eEurope and upon which the trust and viability of the e-enabled community will, to a very large part, depend on. The eEurope 2005 action plan has been drawn up to focus on “the widespread availability and use of broadband

31、networks throughout the Union and the security of networks and information, eGovernment, eHealth and eBusiness“ requiring a supporting infrastructure, which is truly pan-European. To quote COM(2002)263: “By 2005 Europe should have a secure information infrastructure“. ETSI ETSI EG 202 549 V1.1.1 (20

32、06-12) 7 1 Scope The present document gives guidance on the application of security countermeasures to service capabilities. It covers the construction of services from service capabilities and how a security evaluation of a service capability should be performed. The present document examines and g

33、ives guidance on the use of the Composition assurance class defined by the Common Criteria working group in order to be able to answer the question: “if components A and B are evaluated as having security ratings X and Y what is the security rating that can be assigned to the combination of A and B?

34、“ The present document builds on the guidance to the Common Criteria for Information Technology Security Evaluation given in EG 202 387 3 with a particular view to assessing the security of the NGN. In the NGN context, where services are not explicitly defined but are made from combining service cap

35、abilities, the present document gives guidance on the means to apply effective security to both service capabilities in isolation, and to service capabilities in combination. The guidance reviews the service capability model in clause 4 and examines the requirements for security arising from the ser

36、vice capability requirements defined for NGN-R1 in clause 5. The analysed security requirements are presented in the form of ISO/IEC 15408-2 17 functional models. Clause 6 presents a review of the Common Criteria Composition assurance class and describes its impact on the ETSI standardization proces

37、s. Annex A reviews the use of cryptographic techniques in the NGN. A number of assumptions of the design of NGN for security analysis to take place are made on the NGN development process. The assumption in the present document is that the NGN has been developed using top-down decomposition of the s

38、pecification, using techniques of planned validation of the specification, with careful recording of design decisions and validation results. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
