Worm Propagation Modeling and Analysis Based on Quarantine
基于隔离策略的蠕虫传播模型及分析

In recent years,the worms that had a dramatic increase in. the frequency and virulence of such outbreaks have become one of the major threats to the security of the Internet. In this paper,we provide a worm propagating model. It bases on the classical epidemic Kermack-Kermack model,adopts dynamic quarantine strategy, dynamic in- fecting rate and removing rate. The analysis shows that model can efficiently reduce a worm's propagation speed, which can give us more precious time to defend it,and reduce the negative influence of worms. The simulation results verify the effectiveness of the model.
