Telecom Penetration Testing

Telecom penetration testing is authorised, scoped offensive testing of an operator's networks and services to identify exploitable weaknesses before adversaries do. It typically combines IT-style external and internal testing with telecom-specific work on SS7, Diameter, GTP, SIP, RAN, and 5G interfaces, mapped to GSMA security PRDs and frameworks such as MITRE FiGHT.

Telecom Penetration Testing 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 Telecom Penetration Testing in the wider telecom-security picture, review Lawful Interception Abuse Risk, Lawful Interception Architecture, Revenue Assurance, Chain of Custody, O-RAN Interfaces (A1, E2, O1, O2) and Bidding-Down Attack — each entry cross-references back to this page so you can walk the topic in either direction.
