System and Method for Automatic Feedback/Monitoring of Avionics Robustness/Cybersecurity Testing

A system and method for automatic feedback and monitoring of avionics robustness and cybersecurity testing includes a fuzzer for generating fuzzed test cases based on legitimate data inputs and transmitting the test cases to various avionics systems under test (SUT). Individual monitor modules serve as monitors for particular devices, ports, or protocols of the SUT, determining states of the SUT before and after the test cases are introduced into the system by observing responses to system messages and regular system activities. Based on changes in system states, the monitor modules may determine system errors of the SUT, logging any determined errors along with associated test cases and system states for offline analysis.
