Protect Peering Connections with Secure GTP
Secure General Packet Radio Service (GPRS) Tunneling Protocol (GTP) peering
is based on the GTP inspection capabilities available on Cisco stateful
firewall devices, including the Cisco PIX Firewall family, the Adaptive
Security Appliance family, and the Cisco 7600 Firewall Service Module (FWSM).
GTP inspection hardens and protects a GSM operator's peering connections
with roaming partners and the GPRS Roaming Exchange (GRX) by:
- Limiting GTP tunnel connections and traffic to legitimate roaming
partners
- Providing analysis and visibility into GTP sessions and traffic behavior
- Detecting and discarding spoofed or malformed GTP traffic that can
lead to theft of data or identity, inaccurate billing, or fraud
- Hiding the internal network topology from the GRX and other external
networks, exposing only the necessary GPRS service nodes (GSNs)
