ZHANG Xin, LI Kun-lun·Design of Network Behavior Analysis System Based on Association Rules Mining·College of Science and Technology, Nanchang University Design of Network Behavior Analysis System Based on Association Rules Mining With the rapid development of the computer network technology, Internet application further popularization, people in the work and the life rely more and more on various network applications and services. At the same time, some network using issues also will appear, is mainly shown in two aspects: one is excessive network entertainment behavior, the application USES of a lot of network resources and affect the normal network services; On the other hand is network users of harmful behavior, these actions often brings serious the problem of network security. Especially in the campus network, the user groups are mainly students, they are more likely to indulge in Internet chat, online games and other entertainment behavior, and often due to inappropriate network behavior and cause safety issues, or because of interest and curiosity and actively carry out some harmful network behavior. To solve these problems, the study and analysis of the user's network behavior, especially students groups of Internet behavior, limit harmful network behavior occurs, for effective management of campus network resources, strengthen the campus network security have realistic significance. Based on the use of association rules mining technology, on the basis of analysis of the user access to the network through behavior to get the user behavior patterns, judge behavior orientation, abnormal behavior of the network behavior analysis system for research and design. 1 network behavior analysis in the paper...
