UEBA (User and Entity Behavior Analytics)

In telecommunications, UEBA applies behavioral baselines and anomaly detection to users, devices, and Network Functions to surface compromised accounts, abused service tokens, or rogue NF behavior. It complements signature-based detection, especially against insider and supply-chain threats.

UEBA in context

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.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place UEBA in the wider telecom-security picture, review SCP Abuse, RAN, UDR, CER Directive, Core Network and Egress: each entry cross-references back to this page so you can walk the topic in either direction.
