Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The present document explores possible so
18、lutions to comply to the security requirements of TS 187 001 i.1. ETSI ETSI TR 185 012 V3.1.1 (2010-07) 61 Scope The present document presents the results of a study into the feasibility of providing security mechanisms to be implemented in a Customer Premises Network (CPN) that allow the CPN to com
19、ply with the security objectives and requirements of the CPN. The present document identifies the placement of measures in the Customer Network Gateway (CNG) and in the Customer Network Devices (CNDs) that support the end-to-end security architecture of NGN release 3 as defined in TR 180 001 i.20 (N
20、GN-R3 release definition) and TS 187 003 i.18 (security architecture). The present document completes task 7 of the TVRA method defined in TS 102 165-1 i.21 with due account of the remainder of the TVRA for CPNs presented in TR 185 008 i.13 and TR 187 002 i.17. 2 References References are either spe

46、he CPN. The CPN, consisting of a CNG and a number of CNDs, is connected to the NGN as if it were a single NGN terminal connected for signalling purposes through the Gm reference point. Protection of the NGN interconnection and thus protection of the CPN from NGN attacks is out of scope of the presen
47、t document but is covered by the following documents TS 187 001 i.1, TR 187 002 i.17 and TS 187 003 i.18. The CNG offers services to the CNDs within the CPN and the protection of the CNG and its connected CNDs is considered in the present document. However the boundary of the CPN may be compromised
48、by the technologies offered by the CNG and by the CNDs themselves, e.g. a wireless connection between CND and CNG as a broadcast. The security objectives to be met by the CPN are as follows: Confidentiality 1. Information sent to or from a registered user of a CPN should not be revealed to any unaut
49、horized party. 2. Information held within the CNG should be protected from unauthorized access. 3. Details relating to the identity and service capabilities of a CPN user should not be revealed to any unauthorized 3rdparty within the CPN or in the wider NGN. 4. Management Information sent to or from a CPN should not be revealed to any unauthorized party. 5. Management Information held within a CPN should be protected from unauthorized access. Integrity 1. Information held within the CNG s
