Telecom SIEM

A telecom SIEM is a Security Information and Event Management platform that ingests logs and signalling telemetry from across an operator's environment, IT systems plus SS7, Diameter, GTP, SIP, and 5G SBA, and applies correlation, detection, and alerting tuned to telecom-specific threats. It is the analytical heart of a telecom SOC and feeds incident response.

Telecom SIEM 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.

Signaling protocols carry the control-plane messages that set up calls, register subscribers 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 as top-tier telecom risk.

To place Telecom SIEM in the wider telecom-security picture, review 5G SBA, ACL, Core Network Security Assessment, IETF, Network Exposure Function (NEF) and RSA — each entry cross-references back to this page so you can walk the topic in either direction.
