Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TR 187 002 V3.1.1 (2011-04) 10 1 Scope

12、 The present document presents the results of the Threat Vulnerability Risk Analysis (TVRA) for the NGN. The present document follows the method and proforma for carrying out a TVRA defined in TS 102 165-1 i.4 and incorporates material of the NGN threat and risk analysis herein. The present document

13、 identifies security-relevant interfaces in the NGN, identifies security-relevant scenarios for use in the NGN, analyses NGN in terms of security threats and risks by performing a security threat and risk analysis, and classifies the identified vulnerabilities and the associated risk presented to th

14、e NGN. This threat and risk analysis makes a number of assumptions that are believed to hold for typical deployment scenarios of the NGN. NOTE 1: Depending on the actual instantiation of the NGN some of the assumptions declared in the present document may not fully hold and this may alter the associ

15、ated risks. NOTE 2: Whilst the present document is a technical report it identifies requirements for future work. In all cases these requirements are considered indicative pending their ratification in formal ETSI Technical Specifications within the TISPAN Work Programme. 2 References References are

16、 either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents wh
