The author also describes the architecture and functions and the design and the implement of the software. Intrusion detection system (IDS) is very important for network security. At present, the author systematically analyzes the composition and semantics of Snort rules, which may be of great help for creating signature database, then the paper studies the flexibility and self-controllability in the CVE-based Intrusion Detection System, emphasizes not only on analysis of the snort rules, but on the
realization of intrusion detecting based on CVE rules and the implement of the sniffer. Especially, this paper covers the intrusion signature matching methods, and analyzes the weakness when only uses pattern matching in intrusion analysis and presents an improved approach that combines protocol analysis and pattern matching, to dectect attacks. At the same time it gives an example to show how to use this approach. The experimental results show that the rules surely reduce the rate of misd
