- Abstract
The Modbus industry bus protocol is special, and the network intrusion data sample of industrial control system is not balanced. So this paper used OCSVM to construct double contour model combining normal OCSVM model, and abnormal OCSVM model to simulate the normal mode and abnormal mode of system communication. Then it realized the abnormal detection of industrial control system. In order to prevent the OCSVM model from overfitting and the low accuracy of classification, this paper applied the genetic algorithm to the industrial control network by optimizing the dimensionality reduction of the independent variable. This method improved the accuracy of the anomaly detection and reduced the modeling time. Simulation results show that the proposed algorithm is effective for anomaly detection of industrial network .
