Other AbstractThe invention provides a Modbus protocol-oriented fuzz testing method capable of discovering the processing defects of field equipment of an industry control system on Modbus protocol data. The method comprises the steps of dividing a Modbus protocol domain into a static portion and a dynamic portion via expert knowledge, constructing a test data set in the dynamic portion via an abnormal mutation tree method, and greatly filtering fuzz testing cases which do not easily cause faults; integrating the disclosed bug information to construct testing cases, and fusing the testing cases to the fuzz testing cases; mutating one or more testing cases via a genetic algorithm based on the similarity of the disclosed bug information, fusing the one or more testing cases to the fuzz testing cases, finally generating a Modbus protocol-oriented fuzz testing case, designing a response information recognition method of the fuzz testing case, and judging whether defects exist or not. A device for implementing the method works on a Modbus TCP/IP layer, and the processing defects of field equipment on Modbus protocol data can be effectively discovered only by simple point-to-point network configuration.
