Abstract
A recognition method for safety behaviors in an industrial control system for a gas field and a recognition system thereof are provided. The recognition method includes: S, collecting sample data of the industrial control system, and obtaining an analysis report based on the sample data; S, generating a critical application programming interface (API) call dependency graph and a resource dependency graph based on the analysis report; S, converting the critical API call dependency graph and the resource dependency graph into numerical matrixes; S, constructing a detection model according to the numerical matrixes, and then detecting a program abnormal behavior of an industrial control host program based on the detection model, to obtain a recognition result, and the recognition result is a normal behavior or an abnormal behavior. The recognition method and system address issues such as high resource occupancy, timeliness, and inaccuracy in safety behavior recognition for industrial control system.
