Adopt the advanced distributed system combined with intelligent intrusion detection technology is one of the key technologies to be applied in the intrusion detection system.Through the study on grid and intelligent intrusion detection technology,an intelligent Grid Intrusion Detection System(GIDS)is proposed which deploys in the grid environment and uses neural network detection technology.In order to realize the load balance between the detection engines,a scheduling strategy is used based on the resource performance value.In addition,Multiplicative Increase Linear Decrease(MILD)is applied to alerts aggregation.The GIDS,which fully exploits resources in the grid and realizes load balance,has high effectiveness in detecting the malicious attacks under heavy network traffic environment.Experimental results show that the performance of GIDS is good.
