Performance Study of Distributed Multi-Agent Intrusion Detection System
暂无分享,去创建一个
Traditional Intrusion Detection System (IDS) based on hosts or networks no longer meets the security requirements in today’s network environment due to the increasing complexity and distributivity. A multi-agent distributed IDS model, enhanced with a method of computing its statistical values of performance is presented. This model can accomplish not only distributed information collection, but also distributed intrusion detection and real-time reaction. Owing to prompt reaction and openness, it can detect intrusion behavior of both known and unknown sources. According to preliminary tests, the accuracy ratio of intrusion detection is higher than 92% on the average.
