SURVEY PAPER ON CYCLIC WORM PROPAGATION MODEL AND ANALYTICAL WORM PROPAGATION MODEL

Active worm spread automatically in a regular fashion and can be flood into the internet in a very short time. Modelling the spread of active worms can help us to understand, how active worms are spread, and how can be monitor and defend against the propagation of worm effectively. In this paper we describe the worm propagation using the analytical active worm propagation model, which characterize the propagation of worms that employ random scanning. It is optimistic in the sense that worms can still be controlled and pre-generated target list, or internally generated target lists as their target discovery technique. Furthermore, we extend our AAWP model to understand the spread of worms that employ local subnet scanning. In this paper we present the AAWP model to analyze the characteristics of the spread of active worm. In this paper we also describe the model of cycle worm propagation to defend against the future and current worm of compromised system and some prevention mechanism to monitor the spreading of active worm. This article will step through common practices to prevent worm propagation and also examines these results in the analytical worm propagation model.
