Abstract


In recent years , the worms frequent eruptions, has brought huge economic losses , and does not apply to existing anti - virus technology on worms . The worm has become a hot issue . Worm detection technology , however , is still lagging behind , the new worm early warning capability is still very limited . Most of the existing worm research focused on the description and the behavior of a particular worm clear grasp the fundamental network characteristics of less grasp worm propagation characteristics , the situation of research and application of double standards . This article focuses through the establishment of a network worm propagation model worm propagation characteristics , proposed the idea of a controllable worm against worm , the fight against the spread of the model , the theoretical and experimental validation of the above model . Thesis work include : the emergence and development of the worm history review and analysis of the working mechanism of the worm . Research discusses worm , and pointed out the inadequacies of the existing studies exist . Discussed existing worm propagation model , the SI model, KM model , the \Improved model named \for the spread of the worm in massive patch upgrade program and automatically patch has a certain degree of universality . Analysis of the worm against worm ( WAW ) technology and its research status , the definition of controlled worm distributed architecture framework and workflow , and controlled worm as confrontation worms , proposed controlled worm against worm (CW-AW ) thought the model based on the idea to establish the \Using Matlab / Simulink simulation \\
