Abstract: On the studying techniques of the Intrusion Detection System(IDS), this paper develops the IDS model based on the user behavior. The genetic algorithm is applied to the IDS for the accuracy of the pattern warehouse. So it succeeds in combining the IDS and the genetic algorithm. Result of the experiment proves the genetic algorithm is effective and practical.

Key words: network security, intrusion detection, genetic algorithm, pattern warehouse
