Research on the Propagation Model and Prevention Strategy of Industrial Internet Worm Based on Coupled P2P Network

Most existing strategies for benign worms against coupled P2P Industrial Internet worms fail to balance both effective countermeasures and resource consumption. In response, this study investigates a method to counteract the spread of coupled P2P Industrial Internet worms using compound benign worms. The method divides the prevention and control process into three stages: the prevention stage, the pre-counter stage, and the post-counter stage. In different prevention and control stages, different methods are used according to the different propagation characteristics of the worm to achieve effective and economical effects. At the same time, the effects of the coupling average degree and the contact infection rate of benign worms are proposed and added to the SIUR model, so as to better simulate the process of worm propagation. The simulation experiments results show that the countermeasure strategy has good prevention and control effects under different network parameter settings.
