Design And Implementation Of A Worm Defense System Based On Campus Network

The emergence of the Internet has greatly boosted the development of China’sinformation industry, and completely changed people’s lifestyle and habits, and plays arole in promoting social development, accelerate the development of the informationindustry. But the network from the invention so far, has been experiencing networkattack and virus challenge, worm is a period of infection and attacks on the targetsystem and network code, there is often used by hackers worm code to carry out attackson network and host, the Internet not only to the women brought very big convenience,but also let us always feel threatened.Network worms to rapid, diversified communication mode has brought disaster tothe network world. It is through the network to spread the specific information or error,and then lead to network anomaly. Network worms usually includes a main programand program, the main program by reading the configuration file to read and othercomputer information for the current computer network. At present, pose a great threatto the stable operation of the campus network worm propagation, so in this paper thecampus network worms as the research object, the design and implementation ofcampus network worm defense system. From the development trend of practice and thecomputer technology in the field of anti virus can be seen, the development of virusactive defense system becomes more and more important, also be imperative. In thispaper, the development goal is to be able to for the worm behavior of the automaticmonitoring and automatic analysis system, to fundamentally solve the worm on campusnetwork invasion, the establishment of a proactive worm defense system. According tothis train of thought, this paper proposes recognition rules establish a worm, once foundthe campus network data consistent with this rule, such as a program or process calls orillegally in memory on the system process etc.. Some of these behaviors can berelatively high, and some are relatively low, so the assignment to represent suspiciousdegree its height, by setting the value in the defense system, then it can be judgedwhether this behavior is worm behavior.Worm defense system is the focus of this paper, the system of automatic defense function, mainly through the abnormal behavior monitoring different client is collectedand analyzed, thus the outbreak especially because of the network worm caused theoutbreak to make accurate judgments. Worm defense system as an independent software,system and some mainstream anti-virus integration, by the worm detection system fornetwork worm behavior analysis, detection and management, anti-virus software tocomplete the clearance, graphical interface worm management as well as the componentupdates.
