Focuses on protecting network infrastructure, such as Session Border Controllers (SBCs) and core network nodes, from unauthorized access and denial-of-service (DoS) attacks.

Provides the overarching "Baseline Security Controls" for the entire mobile ecosystem. gsma fs.38

GSMA FS.38 is a critical Official Document titled . Developed by the GSMA's Fraud and Security Group (FASG) , it provides a framework for securing Session Initiation Protocol (SIP) communications across fixed, mobile, and converged networks. Overview of GSMA FS.38

Outlines scenarios where SIP vulnerabilities are exploited for financial gain, such as toll fraud or subscription fraud. Technical Recommendations Developed by the GSMA's Fraud and Security Group

As the telecommunications industry transitions from legacy signaling protocols (like SS7) toward IP-based systems, SIP has become the backbone for voice and multimedia services, including and 5G Voice . FS.38 addresses the unique vulnerabilities introduced by this shift, offering a comprehensive guide to identifying and mitigating SIP-based threats. Key Focus Areas

Specifically addresses fraud risks in 5G environments. including and 5G Voice .

By adhering to FS.38, operators can better defend against emerging "all-IP" threats, ensuring that as networks become more open and virtualized, they remain resilient against both traditional and sophisticated cyberattacks.

FS.38 is part of a broader library of security resources that work in tandem to secure modern networks:
