Abstract
Techniques for transport layer signaling security with next generation firewall are disclosed. In some embodiments, a system/process/computer program product for transport layer signaling with next generation firewall includes monitoring transport layer signaling traffic on a service provider network at a security platform; and filtering the transport layer signaling traffic at the security platform based on a security policy.
Claims20
A system, comprising:
- a processor configured to:
- monitor transport layer signaling traffic on a service provider network at a security platform;
- perform rate limiting of messages in the transport layer signaling traffic at the security platform based on a security policy, wherein a transport layer signaling protocol is a signaling transport (SIGTRAN) protocol, and perform state and packet validation of a Stream Control Transport Protocol (SCTP) protocol per payload protocol identifier (PPID) and source/destination IP addresses while performing rate limiting of SIGTRAN protocol messages;
- and
- a memory coupled to the processor and configured to provide the processor with instructions.
A method, comprising:
- monitoring transport layer signaling traffic on a service provider network at a security platform;
- and
- performing rate limiting of messages in the transport layer signaling traffic at the security platform based on a security policy, wherein a transport layer signaling protocol is a signaling transport (SIGTRAN) protocol, and perform state and packet validation of a Stream Control Transport Protocol (SCTP) protocol per payload protocol identifier (PPID) and source/destination IP addresses while performing rate limiting of SIGTRAN protocol messages.
A computer program product, the computer program product being embodied in a tangible computer readable storage medium and comprising computer instructions for:
- monitoring transport layer signaling traffic on a service provider network at a security platform;
- and
- performing rate limiting of messages in the transport layer signaling traffic at the security platform based on a security policy, wherein a transport layer signaling protocol is a signaling is transport (SIGTRAN) protocol, and perform state and packet validation of a Stream Control Transport Protocol (SCTP) protocol per payload protocol identifier (PPID) and source/destination IP addresses while performing rate limiting of SIGTRAN protocol messages.
