Telecom Penetration Testing

Telecom Penetration Testing in context

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

Signaling protocols carry the control-plane instructions that set up calls, register subscribers, hand over sessions 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 FS.11 / FS.19 / FS.20 as a top-tier telecom risk.

To place Telecom Penetration Testing in the wider telecom-security picture, review Bidding-Down Attack, Fuzzing, Vulnerability Assessment, Lawful Intercept, Interconnection and Revenue Assurance.
