Detection and Prevention to Network Worm Virus Based on Segmentation Algorithm

Abstract

This paper Through an analysis of the worm propagation behavior, found that there are certain constraints relationship of network size to the propagation speed of the worm . On this basis, network segmentation algorithm based on DFS is proposed to reduce the size of the network, in order to gain subnet boundaries , in order to further suppress the spread of worms provide a theoretical basis , provide reference and basis for the erection of a network worm isolation system. the method of using DFS network segmentation algorithm based on network topology was proposed to solve large-scale network analysis. It provides a strong theoretical support for fast access network backbone node. The result of experiment shows that the proposed method is effective.
