Abstract

Techniques for Diameter security with next generation firewall are disclosed. In some embodiments, a system/process/computer program product for Diameter security with next generation firewall includes monitoring Diameter protocol traffic on a service provider network at a security platform; and filtering the Diameter protocol traffic at the security platform based on a security policy.

Claims (34)

1. A system, comprising:

a processor configured to:

monitor Diameter protocol traffic on a service provider network at a security platform;

filter the Diameter protocol traffic at the security platform based on a security policy, wherein a signaling transport protocol is a signaling transport (SIGTRAN) protocol;

perform state and packet validation of the Diameter protocol per payload protocol identifier (PPID) and source/destination IP addresses while filtering SIGTRAN protocol messages; and

enforce the security policy using the security platform; 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 the Diameter protocol.

3. The system recited in claim 1 , wherein the processor is further configured to perform security policy enforcement based on the Diameter protocol.

4. The system recited in claim 1 , wherein the processor is further configured to perform state and packet validation of the Diameter protocol based on the security policy.

5. The system recited in claim 1 , wherein the processor is further configured to perform threat prevention based on the Diameter protocol.

6. The system recited in claim 1 , wherein the security platform monitors wireless interfaces including a plurality of interfaces for the Diameter protocol and user data traffic in a mobile core network for a 3G and/or 4G network.

7. The system recited in claim 1 , wherein the processor is further configured to block a message filtered in the Diameter protocol traffic based on the security policy.

8. The system recited in claim 1 , wherein the processor is further configured to block a message filtered in the Diameter protocol traffic or a higher layer of signaling traffic based on the security policy.

9. A method, comprising:

monitoring Diameter protocol traffic on a service provider network at a security platform;

filtering the Diameter protocol traffic at the security platform based on a security policy filter the Diameter protocol traffic at the security platform based on a security policy, wherein a signaling transport protocol is a signaling transport (SIGTRAN) protocol;

performing state and packet validation of the Diameter protocol per payload protocol identifier (PPID) and source/destination IP addresses while filtering SIGTRAN protocol messages; and

enforcing the security policy using the security platform.

10. The method of claim 9 , wherein the security platform is configured with a plurality of security policies based on the Diameter protocol.

11. The method of claim 9 , wherein the method further comprises performing security policy enforcement based on the Diameter protocol.

12. The method of claim 9 , wherein the method further comprises performing state and packet validation of the Diameter protocol based on the security policy.

13. The method of claim 9 , wherein the method further comprises performing threat prevention based on the Diameter protocol.

14. The method of claim 9 , wherein the security platform monitors wireless interfaces including a plurality of interfaces for the Diameter protocol and user data traffic in a mobile core network for a 3G and/or 4G network.

15. The method of claim 9 , wherein the method further comprises blocking a message filtered in the Diameter protocol traffic based on the security policy.

16. The method of claim 9 , wherein the method further comprises blocking a message filtered in the Diameter protocol traffic or a higher layer of signaling traffic based on the security policy.

17. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

monitoring Diameter protocol traffic on a service provider network at a security platform;

filtering the Diameter protocol traffic at the security platform based on a security policy filter the Diameter protocol traffic at the security platform based on a security policy, wherein a signaling transport protocol is a signaling transport (SIGTRAN) protocol;

performing state and packet validation of the Diameter protocol per payload protocol identifier (PPID) and source/destination IP addresses while filtering SIGTRAN protocol messages; and

enforcing the security policy using the security platform.

18. The computer program product recited in claim 17 , wherein the security platform is configured with a plurality of security policies based on the Diameter protocol.

19. The computer program product recited in claim 17 , wherein the computer program product further comprises computer instructions for performing security policy enforcement based on the Diameter protocol.

20. The computer program product recited in claim 17 , wherein the computer program product further comprises computer instructions for performing state and packet validation of the Diameter protocol based on the security policy.
