Red Team

A red team conducts authorised adversary-simulation exercises against an organisation's defences, emulating the tactics, techniques, and procedures of realistic threat actors to stress-test detection and response. Telecom red teaming covers IT estate, signalling interconnect, RAN management, and 5G core, and is typically scoped against frameworks such as MITRE ATT&CK and FiGHT.

Red Team 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.

The mobile core carries subscriber sessions, mobility and policy. 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.

To place Red Team in the wider telecom-security picture, review Threat Intelligence, Risk Assessment, MITRE FiGHT, Grey Routing, Machine Learning (ML) and Telecom Attack Surface Mapping: each entry cross-references back to this page so you can walk the topic in either direction.
