Event Logging

Event logging is the recording of significant events, authentication attempts, configuration changes, error conditions, security alerts, by network systems for forensics, compliance, and operational troubleshooting. Telecom logging spans IT systems, signalling elements, and lawful-interception activations, and feeds the SIEM, fraud, and audit pipelines simultaneously.

Event Logging in context

Subscriber identifiers (IMSI, SUPI, MSISDN, IMEI) anchor authentication, charging and lawful interception. Any protocol that leaks a permanent identifier is treated as a privacy defect, which is why 5G introduced SUCI concealment on the air interface.

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 Event Logging in the wider telecom-security picture, review MNP, SIM, SNMP, 2G, AAA and A5/0 — each entry cross-references back to this page so you can walk the topic in either direction.
