Worm Propagation Modeling and Analysis Based on the Mechanism of Dynamic Quarantine
This paper proposes a universal worm propagating model based on the mechanism of dynamic quarantine.The model defines the dubious state when worm stays in the phase of quarantine and depicts the process of dynamic quarantine explicitly.It also depicts packet loss caused by congestion of some routers and the mankind's initiative in the course of antagonizing the worm,by utilizing dynamic infecting rate and together with dynamic removing and auto-immunized rate. The analysis shows that the system based on the mechanism of dynamic quarantine can slow down a worm's propagation, reduce the number of infected hosts and delay the time when the worms burst out to the peak value.
