TM Forum in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.

Signaling protocols carry the control-plane messages that set up calls, register subscribers and route SMS. SS7, Diameter, GTP-C and SIP are the four dominant families, and interconnect exposure of any of them is treated by GSMA as top-tier telecom risk.

To place TM Forum in the wider telecom-security picture, review CAMARA Project, Telecom Penetration Testing, F1 Interface, Sigma Rules, Zeek and CAP: each entry cross-references back to this page so you can walk the topic in either direction.
