Worm propagation modeling and analysis based on quarantine

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 infecting 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.
