Red Team Exercise

In telecommunications, a Red Team Exercise is an objective-driven adversarial assessment where the auditor is given a target outcome (for example exfiltrate subscriber data, take over a core network function, or disrupt a roaming interface) and is free to choose any technique to reach it. Unlike a scoped pentest, only the goal counts. Red Team Exercises in telecom span signaling, OAM, billing, virtualization layers, and physical sites.

Red Team Exercise in context

The mobile core is where subscriber sessions, mobility and policy live. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF. Core exposure is the difference between a single-subscriber leak and a fleet-wide breach.

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 Red Team Exercise in the wider telecom-security picture, review Pentest, GTP-U Smuggling, GGSN, HLR, HSS and Lateral Movement (Telecom).
