Traffic Capture Fuzzer Data Sheet
Test Suite:
Traffic Capture Fuzzer

The Capture Test Fuzzer generates test cases based on an user-provided traffic capture file. Protocol implementation running on top of Ethernet, IP, UDP, TCP or SCTP transport can be tested with the fuzzer. The Traffic Capture Fuzzer automatically reverse-engineers communications protocols. Once portions of the protocols are reverse-engineered, the TCF builds tests for security vulnerabilities that could be exploited by black-hat hackers.
