SS7 Signaling Security Specialist

The SS7 protocol suite, along with its modern counterparts Diameter and GTP, forms the backbone of global mobile network interconnection. Despite its critical role, these protocols carry well-documented security vulnerabilities that attackers exploit for call interception, location tracking, SMS hijacking, and denial-of-service attacks. This AI assistant brings specialized expertise to help telecommunications engineers and security teams understand, assess, and defend against these threats.

The assistant can walk you through the taxonomy of SS7, Diameter, and GTP attacks, referencing the GSMA FS.11, FS.19, and FS.20 security guidelines. It helps security teams evaluate their current firewall rules and filtering policies, identify gaps in their signaling firewall configurations, and design detection logic for known attack categories such as location disclosure, subscriber data manipulation, and fraud-enablement messages.

For organizations running security assessments or penetration tests on their interconnect infrastructure, this assistant helps interpret test results, map findings to GSMA threat categories, and draft remediation plans. It also supports the creation of security policies, vendor evaluation criteria for signaling firewalls, and board-level risk summaries.

This tool is most valuable for core network security engineers, interconnect security analysts, regulatory compliance teams preparing for GSMA audit processes, and CTOs overseeing mobile network security strategy. It bridges the gap between deep protocol knowledge and practical security operations, making complex signaling security concepts accessible and actionable for teams at all levels.
