TSG SA WG3 (Security)

Overview:

TSG SA WG3 Security is responsible for the security of the 3GPP system, performing analyses of potential security threats to the system, considering the new threats introduced by the IP based services and systems and setting the security requirements for the overall 3GPP system. SA WG3 aims at providing at least the same level of security and confidentiality as the 2nd Generation digital systems (e.g. GSM) and to improve upon this wherever feasible. SA WG3 continuously analyse the security implications of new services being developed.
