The precaution of the network virus and the quantitative analysis of the epidemic situation

Comparing with the traditional host virus, the network virus has more attack ability and is more infectious in open network environment. So it is necessary to set a national virus precaution system to detect and control the network virus epidemic situation. In this paper, a distributed broadband network virus precaution model is introduced. It analyzes the data in the network and discovers the coming virus epidemic situation in time. The quantitative analysis of broadband network virus epidemic situation is given, too. According to the result, we can collect the scale, the speed and the direction of the epidemic situation. Consequently, we can establish effect control policy to reduce harm.
