Network behavior detection based on data stream analysis

To make a better analysis of network behavior,this paper proposed a method of network behavior detection based on data stream analysis. Firstly,it modeled network behavior into formalization by analyzing the network system architecture. And aiming at the characteristics of network behavior,it brought out an expression of network behavior on the and / or graph. Finally,it designed and implemented the network behavior detection algorithm based on data stream analysis. The experiment results show that the proposed algorithm can complete the analysis of the relationship between data stream events in polynomial time,and compared with the other algorithm,the algorithm can effectively improve the network behavior detection precision.
