Abstract: Traditional network intrusion detection system has been unable to meet people’s demands of network security today. This paper presents a new design with internal rules and external rules based on protocol analysis. In external rules, a new threats description language is designed, which is similar to traditional programming languages, understandable and powerful. The internal rules enrich the logic in detection so that complex threats or even which with status can be detected. Compared with the system available, this new design is more accurate and more powerful.

Key words: network security, intrusion detection, protocol analysis
