TETRAPOL

TETRAPOL 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.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how they interlock, is essential for both design and audit work.

To place TETRAPOL in the wider telecom-security picture, review RTSP, 5GNR, ADSL, DOCSIS, MCC and TAC: each entry cross-references back to this page so you can walk the topic in either direction.
