Design And Implementation Of The Platform Of Campus Network Ids

With the rapid development of the Internet, teachers and students on the campus network has had a profound impact in work, life and learning. But the campus network security issues are increasingly taken seriously, and only good solution of the network security issues, the campus network application to healthy and high-speed development. IDS as an important technology are Vigorous development in the Campus Network and become one of the important research areas. For this reason, unfold the research task.This paper prime task studies and implements IDS based on the protocol analyst, based on the demand of Chaoyang teachers'college, and implements in Chaoyang teachers'college campus network, built Campus network IDS platform.First this paper comprehensively and systematically analyzed the IDS history, present situation and development trend. Then, this paper expounds systematically the IDS principle, deeply analysis the TCP/IP protocol, understands packets'standard format, basic characteristics. According to demands of the Chaoyang teachers'college campus network, proposed the campus network IDS platform model. Further, finish general design and detailed design; emphatically resolve various modules, including based packet capture technology on the WinPcap, agreement analytical techniques, intelligent analytical techniques for matching technology, Improvement BM algorithm, automatic sequence rules, etc. Finally, complete IDS based on protocol analysis and rule matching, and implement in Chaoyang teachers'college campus network.
