@@@@Intrusion feature selection can improve the correctness and detection rate of the intrusion detection system effectively. A intrusion feature subset selection algorithm based on Particle Swarm Optimization(PSO)is proposed. Depending on the analyses of correlation between all features of network intrusion data, the PSO algorithm is used to search and choose effective feature subset independently to reduce data dimension in the feature space. The experimental results show that the algorithm can effec-tively remove redundant features, reduce the time of feature selection, ensure detection accuracy and improve detecting speed.
