Design of Intrusion Detection System Based on a New Pattern Matching Algorithm

Intrusion detection technology can help the system to deal with network attacks, extend the security management ability of the system manager and increase the integrality of information security foundation structure. Pattern matching algorithm is the core algorithm of intrusion detection system based on feature matching as well as an algorithm which is universally used in current intrusion detection equipment. A design scheme of intrusion detection system based on pattern matching algorithm is proposed in this paper. Meanwhile, aiming at several key modules of intrusion detection system, a detailed analysis of data acquisition module, protocol processing module, feature matching module, log record module and intrusion response module is also given in this paper.
