Roaming Security in Mobile Networks
5G roaming has become a high-risk entry point for attacks and partner-borne threats, making the roaming exposure point a critical control. This ebook shows how FortiGate roaming firewall with FortiOS-Carrier applies stateful GTP and PFCP inspection across Gp, S8, and N4, enforces GSMA FS2.0 GTP Security, and enables fine-grained policies that reduce fraud and outages.
- Latest roaming threat landscape and GSMA expectations, with stateful checks that shrink attack surface, highlighted by real-world attacks like Liminal Panda
- Practical deployment of IE-based filtering and per-partner GTP profiles, validation of IMSI, APN, RAI, ULI, RAT, IMEI, per-APN rate limits to absorb signaling floods, and extension of protection to N9
- How cross-protocol correlation with Telco SecOps enables GSMA FS.20 Category 3 plausibility checks to detect spoofing, hijacking, and fraud in real time without disrupting legitimate sessions
