Modeling and analyzing the spread of worms based on quarantine

There has been a constant barrage of worms over the internet during the recent past. To develop appropriate tools for thwarting quick spread of worms, researchers are trying to understand the behavior of the worm propagation with the aid of epidemiological models. In this paper a worm propagation model with quarantine strategy is presented and discussed based on the classical epidemic Kermack-Mckendrick model. Global stability of equilibriums of the model is studied. Numerical simulations confirmed the theoretical results.
