Research On Network Intrusion Detection System Based On Snort

Internet has gradually become a part of people's daily work and life along with its fast development. While the network brings unprecedented opportunity to the information of human society, people are also facing increasingly serious network safety problem. Intrusion detection technique is the most important network safety guarantee technique besides firewall. But different from firewall, it is a dynamic recovery technique.Intrusion techniques can be divided into anomaly detection and misuse detection. Currently, the domestic and international research toward intrusion detection are inclined to anomaly detection system, while to the traditional misuse detection system, research concentrates on the aspects of system architecture and detection performance of the super-speed network. Based on these researches, many commercial intrusion detection systems have appeared. The most commonly way used for network intrusion detection is to manually proceeds the router and analyze the firewall's log or use the software developed by Martin...
