Research Of Windows Host Computer Intrusion Detection System Based On Pattern Match

Following the development of Internet technology rapidly and more and more work transferred to this platform,such as government,military affairs,economy,science and technology,education and culture.When Internet offer convenient,free and infinite information, computer security is becoming a focus that people pay close attention to. How to effeciently protect host computer resource and information needs not only perfection of traditional security protecting technology but also application of a kind of new security technology which is the Intrusion Detection system.First,the computer security and intrusion actuality are described.Second,the implement of intrusion detection system and the principle of intrusion detection model are researched,and then a kind of new intrusion detection system based on pattern match is put forward and its implement principle and reproachs are described in detail.This system is designed to protect the resources and information of the important host computer.The effiently data receptor,preprocess,protocol analysis and pattern match and so on data analysis technology and resource monitoring technology are finished with protecting information servers and host computer.The whole system has very beautiful and friendly interface as well as all kinds of useful functions and constitutes a dynamic security system that can protect host computer more effectively.
