Modeling of malicious code propagation in the industrial control network

Abstract

With the development of digitalization, industrial control network have more connections and open to external network, which breaks their “isolation” from Internet and makes them more vulnerable to be attacked especially by malicious code. To model and analyze the impact of different containment strategies for attacks by malicious code in the industrial control network, the SUIQMR model is established to simulate malicious code propagation. Since the industrial control network is often coupled with Internet, industrial control coupling network is also considered in the SUIQMR model and the containment strategies of quarantine,benign worms and honeypot are added into the model to evaluate their effect against malicious code propagation.The simulation results show the effectiveness of our model.
