Abstract: The swift evolution of the internet has delivered convenience to people while also introducing challenges concerning the security of information. Network intrusion detection, which recognises distinct attack behaviours in the network by gathering and analysing network data, is a key piece of technology for information security. However, traditional intrusion detection methods suffer from feature redundancy, ignore the temporal characteristics of data, and are difficult to effectively deal with multiple attack patterns. Therefore, to address the above problems, a multi-agent intrusion detection model based on important feature extraction is proposed in this paper, named MIDI. MIDI first calculates the importance indicator of features in network traffic by combining attention mechanisms to extract features, and then introduces the reinforcement learning method and the time series model to build a multi-agent model to learn various attack modes in the network. Ultimately, the experimental results demonstrate the efficiency and superiority of MIDI compared to traditional intrusion detection models, and the precision on the NSL-KDD and UNSW-NB15 datasets can reach 98.23% and 94.93%, respectively.
Keywords: intrusion detection; importance index; feature extraction; multi-agent.
