Research on Worms Spread and Control Strategy in Complex Networks

Computer viruses and worms spreading in the network depends on the proliferation of network structure. Network structure will affect the virus and worms´ infection rate and scope of computer. This paper take the worm as the targeted, against the network transmission characteristics of real world, discusses the spread of computer viruses and control strategies of different network structures. Papers firstly make clearly what is the complex network and its features, and study what is network worms and the emergence of worms and its development process, understand the current status of the worm, studying focus on the spread of the worm models(simple transmission model, Kermack-Mckendrick Model, SIS model, two-factor model, BCM model-network worm confrontation model). Contact the characteristics of complex network and the worm´s principle, make a little understanding of the worm detection and defense and the network-based control strategies of an important node. Give out effective proposals on the current developments in the worms, in addition to network worm suppression on each host, and by the entire network, we should comprehensivly using the important immune target and contain the virus as the virus control strategy. Strive to create a high reliability of the network.
