  2. ITU Plenipotentiary Conference 2002Resolution PLEN/2 - Strengthening the role of ITU in information and communication network security resolves • to review ITU's current activities in information and communication network security; • to intensify work within existing ITU study groups in order to: a) reach a common understanding on the importance of information and communication network security by studying standards on technologies, products and services with a view to developing recommendations, as appropriate; b) seek ways to enhance exchange of technical information in the field of information and communication network security, and promote cooperation among appropriate entities; c) report on the result of these studies annually to the ITU Council.

  3. ITU-T Study Groupshttp://www.itu.int/ITU-T/ • SG 2 Operational aspects of service provision, networks and performance • SG 3 Tariff and accounting principles including related telecommunications economic and policy issues • SG 4 Telecommunication management, including TMN • SG 5 Protection against electromagnetic environment effects • SG 6 Outside plant • SG 9 Integrated broadband cable networks and television and sound transmission  • SG 11 Signalling requirements and protocols • SG 12 End-to-end transmission performance of networks and terminals • SG 13 Multi-protocol and IP-based networks and their internetworking • SG 15 Optical and other transport networks • SG 16 Multimedia services, systems and terminals • SG 17 Data networks and telecommunication software • SSG Special Study Group "IMT-2000 and beyond" • TSAG Telecommunication Standardization Advisory Group

  4. ITU-T Study Group 17 • Lead Study Group for Communication System Security • Coordination/prioritization of security efforts • Development of core security Recommendations • Existing Recommendations include • Security architecture, model, frameworks, and protocols for open systems (X.800-series, X.270-series) • Trusted Third Party Services (X.842/X.843) • Public-key and attribute certificate frameworks (X.509)

  5. ITU-T SG 17 Security Focus • Authentication (X.509) • Ongoing enhancements as a result of more complex uses • Security Architecture (X.css) • For end-to-end communications • Telebiometrics (X.tb) • Telebiometric methods, devices and solutions for security purposes • Security Management (X.ism) • Risk assessment, identification of assets and implementation characteristics • Mobile Security (X.msec) • For low power, small memory size and small display devices

  6. Security Architecturefor End-to-End Communications

  7. Security studies in ITU-T SG 16 • Security for multimedia systems and services • Question G - “Multimedia Security” • Secure H.323-based IP Telephony • H.530 Security for H.323 mobility (ongoing) • H.235 and associated security profiles • H.248 Media Gateway Decomposition Security • Secure H.320 Audio/Video and T.120 Data Conferencing • Telecommunications for disaster relief • H.SETS Multimedia security aspects

  8. Security studies in other SGs • SG 2 • Draft new ITU-T Rec. E.sec.1 • Telecommunication networks security requirements • Draft new ITU-T Rec. E.sec.2 • Incident organization and security incident handling • SG 9 • ITU-T Rec. J.170 • IPCablecom security specification • SG 13 • Draft new ITU-T Rec. Y.roec • Framework to support emergency communications • SGs 4, 11, 15, SSG • Incorporating security requirements in their Recommendations

  9. Useful References • TSB Circular 147 overviews security work being done in the ITU-T study groups • ITU-T Security Project • Catalogue of ITU-T Recommendations on security • Compendia of security definitions extracted from ITU-T Recommendations • Security workshops (May 2002, Seoul) • Writing safe and secure programs http://www.itu.int/ITU-T/studygroups/com17/cssecurity.html

  10. Security collaboration • ISO/IEC JTC 1, Information Technology • SC 6, Telecommunications and Information Exchange Between Systems • SC 27, IT Security Techniques • SC 37, Biometrics • IETF • Many others
