In this paper,we take the network content audit system as the bypass monitoring equipment,and install a linkage system-audit system-firewall between the network side and the switch side of user host.The main purpose is to identify and block illegal information from the network.Then,the paper introduces a method of network security device linkage based on HTTP packet recognition,which is a technology of information security intrusion detection and prevention based on the network.It is mainly used to solve the existing poor time effectiveness of network security equipment linkage blocking technology limitation.Finally,it is concluded that the method is reliable,practicable,which also has value of popularization by test in school network center.
