英文摘要：

Aiming at the real-time problem for intrusion detection, this paper proposed a highly effective intrusion detection model adopting condensed nearest neighbor rules, named IDMCNN. IDMCNN could be used for training set reduction, which speeded up the training and detecting function for IDS and improved the real-time ability. To verify the performance of IDMCNN on the reduced training set and intrusion detection, performed experiments on famous public dataset KDD CUP99, performance and time consuming of intrusion detection between model proposed and compared other existing approaches among each other. Demonstrated IDMCNN is a highly effective intrusion detection model that keeps performance on detection with high real-time in such a case that the size of training set have been reduced in substantially great extent.
