Telecom Forensics

In telecommunications, Telecom Forensics is the collection, preservation, and analysis of evidence from signaling captures (SS7, Diameter, GTP, SBA), CDRs, OAM logs, and NF state in support of incident investigation, fraud cases, or lawful proceedings. It requires telecom-specific tooling capable of decoding TCAP, MAP, Diameter AVPs, and HTTP/2 service operations.

Telecom Forensics 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 Forensics in the wider telecom-security picture, review Vulnerability Assessment, Threat Hunting (Telecom), NTA, Telecom SIEM, Risk Assessment and Telecom Reconnaissance: each entry cross-references back to this page so you can walk the topic in either direction.
