The interconnection between the heterogeneous networks causes network security become more complex,and the isolated security strategy is no more valid.For the infective and epidemic external network attack,this paper presents an anomaly detection mechanism based on the principle of Human Immune System（HIS）,which is applied in complex heterogeneous network and induces network entity to collaboratively work in order to effectively detect traffic anomaly from network attack.Simulation experimental results show that this anomaly det...
