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 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.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking and lawful-interception abuse. The common thread is that most attacks exploit the inherited trust model of legacy signaling. SS7 and Diameter were designed for a closed operator community that no longer exists.

To place UEBA in the wider telecom-security picture, review SCP Abuse, RAN, UDR, CER Directive, Core Network and Egress.
