The invention provides a power-grid industrial control protocol vulnerability mining system and method based on fuzzy test. The system includes a traffic collection module, a message format identification module, a fuzzy test module and a server monitor module; the traffic collection module, the message format identification module, the fuzzy test module and the server monitor module are connected sequentially in series. The invention provides the power-grid industrial control protocol vulnerability mining system and method based on fuzzy test, which solve a power-grid industrial control protocol vulnerability mining problem. By the use of the system and method provided by the invention, a power-grid industrial control protocol can be flexibly selected according to a power-grid industrial control special circumstance, so that efficiency and accuracy of the fuzzy test can be effectively improved.
