摘要： 分析了蠕虫病毒在一个封闭的计算机群中传播的过程,提出了一个离散的蠕虫传播模型,并且把该模型和CodeRedv2蠕虫的真实传播数据进行了比较,通过比较发现该模型较好地反映了随机扫描蠕虫的传播规律·进一步把该模型做了推广,考虑选择性随机扫描(Selective-randomscan)蠕虫的传播规律,通过推广后的模型可以发现,在一个封闭的计算机群中,各个小网络中的易感主机数变化越大,蠕虫传播的速度越快·

Abstract: Based on the analysis of worms propagation in a close computer group, a new discrete worms propagation model is presented and compared with the real propagation data collected by CAIDA, it is found that the model reflects properly the active role of worms propagation. By extending further the model, the behavior of worms which propagate in the form of selective-random scan is considered and it is concluded that in a close computer group the greater the number of vulnerable computers varies in each and every small network, the quicker the worms propagate.
