Abstract: Snort is an opensource intrusion detection system. It detects intrusion with the static rule sets. The paper analyses the rationale and model of intrusion detection system. It introduces how to configure the static rule sets of Snort, describes a method of making dynamic rule sets according to the threshold of statistics flow and the threshold of alert frequency, this method improves and enhances the deployment of flexibility Snort should have.

Key words: intrusion detection system (IDS), rule set, dynamic configuration, Snort
