As mobile networks transition to LTE and 5G, securing Diameter signaling is essential to prevent fraud, privacy breaches, and denial-of-service attacks. The GSMA FS.19 framework provides operators with critical guidelines to detect, mitigate, and prevent threats targeting Diameter interconnects.
As a GSMA member and global telecom security leader, P1 Security fully supports FS.19 and provides advanced solutions that help operators implement and reinforce these security measures.
What is GSMA FS.19?
FS.19 outlines best practices for securing Diameter signaling used in LTE and 5G networks. It focuses on:
✅ Traffic Monitoring: Ensuring real-time visibility into Diameter signaling for anomaly detection.
✅ Firewall Implementation: Blocking unauthorized messages and enforcing security policies.
✅ Threat Categorization: Identifying risks and applying protective countermeasures.
By following FS.19, operators can strengthen their Diameter security posture, safeguarding their networks and subscribers from evolving cyber threats.
Going Beyond FS.19: Advanced Security for Diameter Networks
While FS.19 provides a solid foundation, modern threat actors are constantly developing new attack techniques. To stay ahead, operators need continuous monitoring, proactive threat detection, and intelligence-driven protection.
