Highlights of what’s new since GSC-10
Two new ITU-T Questions:– Q.15/13, NGN security – Q.17/17, Countering spam by technical means
38 security Recommendations are under development in Study Group 17
Other SGs are developing security Recommendations for specific technologies – for example 5 on NGN security

Q.15/13 – NGN Security
Recognizing that security is one of the defining features of NGN, it is essential to put in place a set of standards that will guarantee, to the maximum degree possible, the security of the telecommunications infrastructure as PSTNs evolve to NGNs.
The NGN Security studies must address and develop network architectures that:
- Provide for maximal network and end-user resource protection
- Allow for highly-distributed intelligence end-to-end
- Allow for co-existence of multiple networking technologies
- Provide for end-to-end security mechanisms
- Provide for security solutions that apply over multiple administrative domains
GSC: GSC: Standardization Advancing Global Standardization Advancing Global CommunicationsCommunications
Q.17/17 – Combating spam by technical means
Spam has become a widespread problem causing a complex range of problems to users, service providers, and network operators around the globe. While spam was originally used to send unsolicited commercial messages, increasingly spam messages are being used to spread viruses, worms, and other malicious code that negatively impact the security and stability of the global telecommunication network. Spam may include the delivery of phishing and spyware. It is a global problem that requires a multifaceted, comprehensive approach.
Study items to be considered include, but are not limited to:
- What risks does spam pose to the telecommunication network?
- What technical factors associated with the telecommunication network contribute to the difficulty of identifying the sources of spam?
- How can new technologies lead to opportunities to counter spam and enhance the security of the telecommunication network?
- Do advanced telecommunication network technologies (for example, SMS, instant messaging, VoIP) offer unique opportunities for spam that require unique solutions?
- What technical work is already being undertaken within the IETF, in other fora, and by private sector entities to address the problem of spam?
- What telecommunication network standardization work, if any, is needed to effectively counter spam as it relates to the stability and robustness of the telecommunication network?

Closing 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 keyso 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

GSC: GSC: Standardization Advancing Global Standardization Advancing Global CommunicationsCommunications
Q.6/17 Draft Recommendations 1/21. Overview of Cybersecurity (X.cso)
– This Recommendation provides a definition for Cybersecurity. The Recommendation provides a taxonomy of security threats from an operator point of view. Cybersecurity vulnerabilities and threats are presented and discussed at various network layers.
– Various Cybersecurity technologies that are available to remedy the threats include: Routers, Firewalls, Antivirus protection, Intrusion detection systems, Intrusion protection systems, Secure computing, Audit and Monitoring. Network protection principles such as defence in depth, access and identity management with application to Cybersecurity are discussed.
