摘　　要：对比于传统的主机病毒,在开放式网络环境中,网络病毒疫情的蔓延更加迅速、破坏力也更强。建立行之有效的预警体系,是尽早发现新型网络病毒,并控制其蔓延的有力举措。本文研究主动式病毒疫情预警体系结构模型,实时分析网络上的疫情信息;通过基于流量的检测,实现对于新型未知网络病毒的挖掘。Compared to traditional host virus, the epidemic of network virus is more infectious and destructive in the open network environment. It is an important way to build an operatively procaution architecture for finding the new network virus and controlling its infection timely. In this paper, a model of active epidemic procaution is studied to analyze the network epidemic information in real time. Then we present an algorithm to detect unknown network virus based on network dataflow.
