Gsma Fs.38 (2027)

Here is a detailed look at that feature and why it matters:

. It establishes a comprehensive framework for securing Session Initiation Protocol (SIP) across modern telecommunications networks, including VoLTE, VoNR, and 5G. Core Purpose gsma fs.38

is the foundational global standard for SIP (Session Initiation Protocol) Network Security within the telecommunications industry. Here is a detailed look at that feature and why it matters:

Gaining control over core network nodes. Gaining control over core network nodes

Operating under the assumption that an attacker may eventually bypass peripheral defenses, FS.38 dictates strict validation for internal nodes. This covers core infrastructure elements located directly behind the SBCs, such as: Call Session Control Functions (P-CSCF, I-CSCF, S-CSCF) Telephony Application Servers (TAS) Media Gateway Control Functions (MGCF) 4. Non-SIP Supporting Nodes

For years, telecom equipment manufacturers and software vendors defaulted to an all-inclusive answer during the procurement process: when asked if their systems were secure and optimized for performance, the response was nearly always a simple "Yes".
