7 Q.15/13 – NGN SecurityRecognizing 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
8 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?
