| With the development of computer network, some problems of network security always appear on the network of the company (Jiangsu Fujitsu telecommunication Technology company JFTT). The single firewall can not protect the network security. So it is necessary to create a new system. Under this background, to create an intrusion detection system ,which is applicable to the status of the network of JFTT,is good solution.the author completed some work in the article.1) researches the topology structure of the network of JFTT.2) analysis and researches the model of intrusion detection system .3) the author designs a model of intrusion detection system The principle is to use a data distribution frontage, and an array of IDS sensor to complete the intrusion detection.4) In the article the author describes the model of data distribution.,5) The author describes a method of detection that based on protocol analyzing and mode matching to detect data,6) The author summarizes point of view and proposed the research direction in the future at the end of the article. |
