Abstract:
1. A method for testing and analyzing a security vulnerability of a multi-device network system to protocol abuse of a network communications protocol, the method implemented by a security analyzer device, comprising: establishing a first communication link between a member network device-under-analysis (DUA) of the multi-device network system and the security analyzer device; establishing a second communication link between a member network device-under-observation (DUO) of the multi-device network system and the security analyzer device, the DUA and the DUO being distinct member devices of the multi-device network system; attacking the DUA multiple times, the attacks comprising sending to the DUA through the first communication link test messages that are invalid with respect to the network communication protocol; during and after attacking the DUA, monitoring, with the security analyzer, outputs from the DUO received over the second communication link; determining, based on the outputs received from the DUO, whether the multi-device network system includes a security vulnerability; responsive to a determination that the multi-device network system includes a security vulnerability, based on the outputs received from the DUO, identifying which attack causes the security vulnerability.
