: Techniques used by adversaries to intercept or access confidential communications.
If you need to dig deeper into the technical "how," FS.38 defines the following specific mechanisms: gsma fs.38
: Outlines potential SIP-based attacks including fraud, privacy breaches, and Denial of Service (DoS) attacks. : Techniques used by adversaries to intercept or
: Emphasizes protecting the core network nodes located behind border security elements like Session Border Controllers (SBCs) . gsma fs.38
FS.38 works alongside other standards like GSMA FS.21 to promote protocol correlation . This involves comparing data fields across different protocols (e.g., SIP, Diameter, SS7) to identify discrepancies that might signal fraudulent activity. Testing and Assessment Requirements
The specification moves away from the traditional central cloud (hyperscaler model) toward a network of autonomous "Stores."
