MITRE FiGHT (5G Hierarchy of Threats)

In telecommunications, MITRE FiGHT is a knowledge base of adversary tactics, techniques, and procedures specifically observed or theorized against 5G networks. Modeled after MITRE ATT&CK, it covers RAN, core, MEC, and management plane techniques and is used by operators to map detection coverage and to align red team exercises with realistic 5G threats.

MITRE FiGHT 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.

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.

To place MITRE FiGHT in the wider telecom-security picture, review Red Team, User Plane Security, Vulnerability Management, Patch Management, Risk Assessment and Telecom Reconnaissance.
