20 GSC 20 Concluding Observations Security is everybody's business Collaboration with other SDOs is necessary Security needs to be designed in upfront Security must be an ongoing effort Systematically addressing vulnerabilities (intrinsic properties of networks/systems) is key so that protection can be provided independent of what the threats (which are constantly changing and may be unknown) may be – X.805 is helpful here

22 GSC 22 Additional material on recently approved security Recommendations in Study Group 17

23 GSC 23 Three main issues that X.805 addresses The security architecture addresses three essential issues: What kind of protection is needed and against what threats? What are the distinct types of network equipment and facility groupings that need to be protected? What are the distinct types of network activities that need to be protected? X.805

24 GSC 24 X.805: Security Architecture for End-to-End Communications Vulnerabilities can exist in each Layer, Plane and Dimension 72 Security Perspectives (3 Layers Ò 3 Planes Ò 8 Dimensions) X.805

25 GSC 25 X.805: Three security layers Each Security Layer has unique vulnerabilities, threats Infrastructure security enables services security enables applications security 1 - Infrastructure Security Layer: Fundamental building blocks of networks services and applications Examples: –Individual routers, switches, servers –Point-to-point WAN links –Ethernet links 2 - Services Security Layer: Services Provided to End-Users Examples: –Frame Relay, ATM, IP –Cellular, Wi-Fi, –VoIP, QoS, IM, Location services –Toll free call services 3 - Applications Security Layer: Network-based applications accessed by end-users Examples: –Web browsing –Directory assistance – –E-commerce X.805

26 GSC 26 Security Planes represent the types of activities that occur on a network. Each Security Plane is applied to every Security Layer to yield nine security Perspectives (3 x 3) Each security perspective has unique vulnerabilities and threats X.805: Three security planes 1 - End-User Security Plane: Access and use of the network by the customers for various purposes: –Basic connectivity/transport –Value-added services (VPN, VoIP, etc.) –Access to network-based applications (e.g., ) 2 - Control/Signaling Security Plane: Activities that enable efficient functioning of the network Machine-to-machine communications 3 - Management Security Plane: The management and provisioning of network elements, services and applications Support of the FCAPS functions X.805

28 GSC 28 X.805 Provides A Holistic Approach: Comprehensive, End-to-End Network View of Security Applies to Any Network Technology Wireless, Wireline, Optical Networks Voice, Data, Video, Converged Networks Applies to Any Scope of Network Function Service Provider Networks Enterprise Networks Government Networks Management/Operations, Administrative Networks Data Center Networks Can Map to Existing Standards Completes the Missing Piece of the Security Puzzle of what to do next X.805

29 GSC 29 Security Management Information security management system – Requirements for telecommunications (ISMS-T) specifies the requirements for establishing, implementing, operating, monitoring, reviewing, maintaining and improving a documented ISMS within the context of the telecommunications overall business risks leverages ISO/IEC 17799:2000, Information technology, Code of practice for information security management based on BS :2002, Information Security Management Systems Specifications with Guidance for use X.1051

35 GSC 35 Telebiometrics A model for security and public safety in telebiometrics that can assist with the derivation of safe limits for the operation of telecommunications systems and biometric devices provide a framework for developing a taxonomy of biometric devices; and facilitate the development of authentication mechanisms, based on both static (for example finger-prints) and dynamic (for example gait, or signature pressure variation) attributes of a human being A taxonomy is provided of the interactions that can occur where the human body meets devices capturing biometric parameters or impacting on the body X.1081

36 GSC 36 Telebiometric Multimodal Model: A Three Layer Model the scientific layer 5 disciplines: physics, chemistry, biology, culturology, psychology the sensory layer – 3 overlapping classifications of interactions video (sight), audio (sound), chemo (smell, taste), tango (touch); radio (radiation) - each with an out (emitted) and in (received) state behavioral, perceptual, conceptual postural, gestural, facial, verbal, demeanoral, not-a- sign the metric layer 7 SI base units (m, kg, s, A, K, mol, cd) X.1081
