Abstract: “Self-duplicating, self-propagating malicious codes known as computer worms spread themselves without any human interaction and launch the most destructive attacks against computer networks. In this paper, we have successfully detected the worm propagation characteristics of different and using permutation scanning to find the worms using branch process model to provide total number of scan that ensure the worm will eventually die out.”
