2. www.oasis-open.org Outline • Introduction to ITU • Security work at ITU Study Groups • SG 17 Security work • Higlight of Current Activities • Challenges

3. Study Group Organization (WTSA) (TSAG) ITU-T Telecommunication standardization of network and service aspects ITU-D Assisting implementation and operation of telecommunications in developing countries ITU-R Radiocommunication standardization and global radio spectrum management What is International Telecommunication Union (ITU) ? • SG 17, Security, Languages and Telecommunication Software • Lead Study Group on Telecommunication Security • SG 2, Operational Aspects of Service Provision, Networks and Performance • SG 4, Telecommunication Management • SG 5, Protection Against Electromagnetic Environment Effects • SG 9, Integrated Broadband Cable Networks and Television and Sound Transmission • SG 11, Signalling Requirements and Protocols • SG 13, Next Generation Networks • SG 15, Optical and Other Transport Network Infrastructures • SG 16, Multimedia Terminals, Systems and Applications • SG 19, Mobile Telecommunication Networks • Headquartered in Geneva, is the UN specialized agency for telecom

4. Strategic Direction Cybersecurity – one of the top priorities of the ITU • ITU’s role in implementing the outcomes of the World Summit on the Information Society (WSIS) Plenipotentiary Resolution 140 (2006) • Study of definitions and terminology relating to building confidence and security in the use of information and communication technologies Plenipotentiary Resolution 149 (2006) • WTSA-04 Resolution 50, Cybersecurity – Instructs the Director of TSB to develop a plan to undertake evaluations of ITU-T “existing and evolving Recommendations, and especially signalling and communications protocol Recommendations with respect to their robustness of design and potential for exploitation by malicious parties to interfere destructively with their deployment” • WTSA-04 Resolution 52, Countering spam by technical means – Instructs relevant study groups “to develop, as a matter of urgency, technical Recommendations, including required definitions, on countering spam”

5. Highlights of current activities (1) • ITU Global Cybersecurity Agenda (GCA) • A Framework for international cooperation in cybersecurity • Five key work areas: Legal, Technical, Organisational, Capacity Building, International Cooperation • High-Level Experts (HLEG) working on global strategies • GCA/HLEG met 26 June 2008 to agree upon a set of recommendations on all five work areas for presentation to ITU Secretary-General • ISO/IEC/ITU-T Strategic Advisory Group on Security • Coordinates security work and identifies areas where new standardization initiatives may be warranted. Portal established. Workshops conducted. • Identity Management • Effort jump started by IdM Focus Group which produced 6 substantial reports (265 pages) in 9 months • JCA –IdM and IdM-GSI established – main work is in SGs 17 and 13

6. Highlights of current activities (2) • Core security (SG 17) • Covering frameworks, cybersecurity, countering spam, home networks, mobile, web services, secure applications, telebiometrics, etc. • Work underway on additional topics including IPTV, multicast, security; risk management and incident management; traceback, Bots, Privacy, • Questionnaire issued to developing countries to ascertain their security needs • Updated security roadmap/database, compendia, manual; strengthened coordination • Security for NGN (SG 13) • Y.2701: Security Requirements for NGN Release 1 • Y.2702: NGN Authentication and Authorization Requirements • Y.NGN SecMechanisms: NGN Security Mechanisms and Procedures • Y.NGN Certificate: NGN Certificate Management • Y.AAA: Application of AAA for Network Access Control in UNI and ANI over NGN

7. PDA Cellular At your Desk In the Air Managed Office On the Road At Home In Town • People have multiple identities, each within a specific context or domain • Work – me@company.com • Family – me@smith.family • Hobby – me@icedevils.team • Volunteer – me@association.org IdentityConnecting users with services and with others (Federation) Collaboration PC Video Voice Telephony Smart Phone Whatever you’re doing (applications) Whatever you’re using (devices) Web Apps ERP Wherever you are (across various access types) • Network Identity is essential • Need end-to-end trust model

8. Challenges Addressing security to enhance trust and confidence of users in networks, applications and services • With global cyberspace, what are the security priorities for the ITU with its government / private sector partnership? • Need for top-down strategic direction to complement bottom-up, contribution-driven process • Balance between centralized and distributed efforts on security standards • Legal and regulatory aspects of cybersecurity, spam, identity/privacy • Address full cycle – vulnerabilities, threats and risk analysis; prevention; detection; response and mitigation; forensics; learning • Marketplace acceptance of Information Security Management System (ISMS) standards (ISO/IEC 27000-series and ITU-T X.1051) – the security equivalent to ISO 9000-series • Effective cooperation and collaboration across the many bodies doing cybersecurity work • Informal security experts network – needs commitment There is no “silver bullet” for Cybersecurity
