Abstract


Network Intrusion has been a frequently discussed issue without a cool solution. A variety of methods are proposed by professionals for intrusion prevention and management, and these methods focus on different aspect in the technique level. The question is how to resist against network intrusion and where to start.In this paper, we base our recently research on text clustering and classification techniques and try to link all the elements in the network together by mining and association, in order to discover logic relevance like "beer and diapers" . We examine and eliminate the network intrusion from a new perspective. We focus on the proposed model and the possible results via this new model. Category clustering analysis is an analytical tool in machine learning, pattern recognition and computer vision. The traditional category clustering is unsupervised, and it is widely used because of its low level of human interaction and little cost. However, the problem with unsupervised learning is that it depends on some assumptions, e.g., the assumption that type distribution is uniform and Eigen-values are equal, which may not be able to resolve new problems we encountered. So this paper takes lot of consideration into the behavior characteristics of its original network intrusion.After all, it is a new information world with globalization, and people are complaining the network intrusion while we are accumulating huge amount of information of intrusion packets, coding, system logs , syslogd and network flows. When such information is used for category clustering analysis, expected results could be obtained under human’ s supervision or interaction.Our system proposed a new perspective for network intrusion detection and prevention. A new criterion is suggested in a macro way to judge between the network behavior and the various network devices.
