Abstract:
The paper introduces a device linkage system on firewall between the network side and the switch side of user host,and introduces the audit system connected in parallel between the hubs and switches.Then,the paper introduces a method based on HTTP packet recognition network security device linkage,which is a technology of information security intrusion detection and prevention based on the network.It is mainly used to solve the existing network security equipment linkage blocking technology limitation poor problem.Finally,the test result shows that the method is practical and effective.
