Research on Virus Spreading and Protection on Internet

This paper has studied virus spreading an protectional based on complex network theory and full understanding characteristic of Internet. The authors reviewed the computer virus propagation model and computer virus spread threshold theory in association network and associated network. And we analyzed Internet virus immune mechanism. The study shows that different protection strategies have different effectiveness on different structure network. Stochastic immunization strategy combined with target immune strategy to protection Internet virus propagation has best results.
