Indicators of Compromise (Telecom IoCs)

Indicators of Compromise are the observable artifacts, IP addresses, domain names, file hashes, signalling patterns, anomalous Global Titles or Diameter realms, that suggest a security incident has occurred. Telecom-specific IoCs include unusual MAP operations, GTP from unexpected peers, and fraud-pattern call detail records. IoCs feed SIEM detection rules and threat-intelligence sharing.

Indicators of Compromise (Telecom IoCs) 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.

Security controls span signaling firewalls (SS7/Diameter/GTP screening), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36.

To place Indicators of Compromise (Telecom IoCs) in the wider telecom-security picture, review Global Title Abuse, IPS, PCAP, STIR/SHAKEN, 1G and 5G SBA — each entry cross-references back to this page so you can walk the topic in either direction.
