Abstract: The immuncsoftman is provided with adaptability, intelligence and collaboration, so it is used to monitor distributed dynamic network environment in real time. Most of Distributed Intrusion Detection System will produce large amounts of alarm information and the false-alarm rate is also high, which affects the effectiveness of intrusion detection.To address this issue, groups of immuncsoftman intrusion detection model based on trust correlation was proposed.Through the trust correlation algorithms the credibility of the Immune-softman producing alarm can be measured. Simulations show that the groups of immuncsoftman intrusion detection model based on trust correlation can improve the accuracy of intrusion detection alerts.
