Research and Control of Computer Virus Network Transmission

With the development and advantages of network and information technology, the security of computer and network systems is threatened by viruses that are spreading over the Internet. Therefore, the study on the control of computer virus network transmission has become a major concern. In this context, the development process of a computer virus was investigated, and then the research progress of the computer virus propagation model both locally and abroad was analyzed. The loss caused by a computer virus to the society and the economy was also pointed out, and the development trend of the virus infection rate in recent years was examined. In addition, the computer virus defense technology was evaluated, and the transmission mode of computer virus was investigated. The mathematical model of computer virus network transmission based on the SIS model of biological virus transmission was constructed. Then, the model was simulated and analyzed under different models of both local and wide area networks. Results suggest that the initial period of the computer virus infection is the most vulnerable period and is most favorable to controlling the computer virus. These results provide a favorable reference for controlling the computer virus network transmission.
