filter the network layer signaling protocol traffic at the security platform based on a security policy, wherein the network layer signaling protocol is a Signaling Connection Control Part (SCCP) protocol, wherein a signaling transport protocol is a signaling transport (SIGTRAN) protocol; and
perform state and packet validation of the SCCP protocol per payload protocol identifier (PPID) and source/destination IP addresses while filtering SIGTRAN protocol messages; and
a memory coupled to the processor and configured to provide the processor with instructions.
2. The system recited in claim 1 , wherein the security platform is configured with a plurality of security policies based on a Signaling Connection Control Part (SCCP) protocol.
3. The system recited in claim 1 , wherein the processor is further configured to perform security policy enforcement based on the network layer signaling protocol.
