Abstract:

In this paper, an improved conditional generative adversarial network algorithm was proposed, and the Wasserstein distance was added to measure the distance between synthetic and real samples, for solving the instability problem that cause the generator gradient to disappear when two types of samples were ignored to overlap in CGAN. The effectiveness of the algorithm was verified on the UCI dataset with different imbalance rates. Then the WCGAN-SVM intrusion detection model of industrial control system was constructed and verified on the industrial control dataset SWaT. The experimental results show that the method increases the accuracy of detecting attack samples by 3.51% and decreases the false alarm rate and the false negative rate by 2.29% and 2.19% compared with SVM.

Key words: ICS, intrusion detection, WCGAN, unbalance data, SVM
