In order to improve the effect of network intrusion detection, a network intrusion detection model based on selec- tion feature of intelligent optimization algorithm is proposed. The intelligent optimization algorithm is used to select the network intrusion features to obtain the important contribution feature for the detection result, and remove the invalid features. The sup- port vector machine is employed to establish the classifier of intrusion detection. The KDD99 dataset is adopted to analyze the model performance. The results show that the model can improve the accuracy of network intrusion detection, and its detection speed can meet the requirement of network security practical application.
