Abstract:

In response to the new risks and challenges bring about by the rapid changes in the current cyberspace security situation, an intrusion detection method optimized by feature selection based on correlation analysis and tree Parzen estimation (TPE) is proposed. Fistly, the data dimensions are compressed by the method of data feature selection based on correlation analysis. Secondly, feature filtering is performed on the original data set, and a new feature subset is generated. Finally, the random forest algorithm is optimized using the TPE algorithm based on sequential model-based global optimization. Experimental results show that the proposed method has higher detection efficiency while improving the overall performance compared with other intrusion detection methods using machine learning algorithms, and effectively improves the practicability of intrusion detection technology.

Key words: network security, intrusion detection, feature selection, tree Parzen estimation
