Technical Specification Group Service & System Aspects, Working Group 3 on Security and Privacy, Subcommittee on Lawful Intercept | SA3-LI
SA3-LI provides requirements and specifications for facilitating lawful
interception in 3GPP systems. Lawful interception is a security process
in which a service provider or network operator is legally obligated to
collect and provide law enforcement with intercepted communications of
private individuals or organisations. However, technical features that
enable lawful interception can be abused by state actors or exploited
by malicious actors. In recent years, the main actors involved in
influencing and shaping these standards, other than companies such as
Nokia and Ericsson, have been governments primarily from Europe, North
America, and their respective national law enforcement agencies. Other
actors participating in this subcommittee include telecommunication
infrastructure providers, network providers, cybersecurity companies,
network equipment providers and consulting groups working on behalf of
governments.
- Published technical specifications: TS 33.128, TS.127 and TS.126 specify the implementation, architecture, and requirements of lawful intercept in 5G networks, addressing the more dynamic and flexible nature of virtualisation and how it impacts security considerations.
