Detection Engineering

Detection engineering is the discipline of designing, building, testing, and maintaining the rules, queries, and analytics that turn telemetry into actionable alerts. Telecom detection engineering spans IT (EDR, SIEM) and signalling (SS7/Diameter/GTP/SIP/N32 monitoring), and is typically organised against MITRE ATT&CK and the telecom-specific FiGHT knowledge base.

Detection Engineering in context

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.

Roaming and interconnect are where two operators exchange signaling and user-plane traffic. Trust boundaries here are the primary attack surface for location tracking, SMS interception and fraud, which is why GSMA now mandates SEPP with PRINS on 5G interconnect.

To place Detection Engineering in the wider telecom-security picture, review Diameter Interconnect Security, Ingress, Integrity, Mitigation, Monitoring and N32 Interface (5G) — each entry cross-references back to this page so you can walk the topic in either direction.
