GSMA FS.11: Strengthening SS7 Security in Mobile Networks

As mobile networks continue to evolve, securing Signalling System No. 7 (SS7) interconnects remains a top priority. The GSMA FS.11 framework provides essential guidelines for protecting SS7 signaling traffic from security threats, ensuring a more resilient telecom ecosystem.

As a GSMA member and security leader, P1 Security fully supports FS.11 and provides advanced solutions that help operators implement, enhance, and maintain strong SS7 security.

What is GSMA FS.11?

GSMA’s FS.11 guidelines offer a structured approach to monitoring, filtering, and securing SS7 interconnects, helping operators protect against threats such as fraud, tracking, and unauthorized access. The framework includes:

Traffic Monitoring: Analyzing SS7 signaling in real time to detect anomalies.
Firewall Implementation: Defining and enforcing security rules to filter malicious traffic.
Threat Categorization: Identifying and mitigating different levels of security risks.

By following FS.11, operators can improve their security posture and minimize risks across global telecom networks.

Enhancing FS.11 Implementation with Advanced Security Solutions

While FS.11 lays a strong foundation for SS7 security, operators can benefit from advanced threat detection, real-time monitoring, and proactive intelligence to stay ahead of evolving threats.
