Suricata

In telecom networks, Suricata is an open-source network IDS/IPS and security monitoring engine that can inspect traffic in real time, parse many protocols, and emit rich logs and alerts. It is commonly deployed at telecom perimeters and inside data centers as a base layer for NDR.

Suricata in context

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how the specs interlock (for example 3GPP TS 33.501 with GSMA FS.34 for 5G SBA security), is essential for both design and audit work.

To place Suricata in the wider telecom-security picture, review SIRT, SLH-DSA, SHA, ML-DSA, OpenSSL and HMAC-SHA256.
