The security of computer networks plays a strategic role in modern computer systems. In order to enforce high protection levels against malicious attack, a number of software tools have been currently developed. Intrusion Detection System has recently become a heated research topic due to its capability of detecting and preventing the attacks from malicious network users. A pattern matching IDS for network security has been proposed in this paper. Many network security applications rely on pattern matching to extract the threat from network traffic. The increase in network speed and traffic may make existing algorithms to become a performance bottleneck. Therefore it is very necessary to develop faster and more efficient pattern matching algorithm in order to overcome the troubles on performance.
