Fuzz Testing

Validation technique that feeds malformed or random inputs to surface robustness defects.

Fuzz testing systematically generates malformed CAN frames, UDS messages, protocol stack inputs, or file content and observes whether the target panics, hangs, or violates an invariant. In automotive cybersecurity it is the standard tool for stress-testing protocol stacks and parsers on ECUs and gateways.
