摘要
僵尸网络对当前互联网产生巨大危害,基于漏洞扫描的蠕虫是僵尸的主要传播方式和载体.针对蠕虫的传播,现有模型大多以SIR模型为基础,假设主机在免疫之后就不会再被感染.由于僵尸中可能存在多个蠕虫,因此使得免疫主机还可能回归到易感染状态.考虑到此因素,本文在SIR模型的基础上,提出一种回归的RSIR僵尸网络传播模型.给出了模型的描述和数学公式,并对模型进行了分析.实际数据仿真结果显示,模型是有效的.
Botnet produces great harm to the Internet.Worms that bases on vulnerability scanning is the main carrier and mode of transmission of the botnet.According to the transmission properties of worms,most of the existing models based on the SIR model assume that the immune hosts couldn't be infected again.Owing to multiple worms that may exist in the botnet,the immune hosts may also come to susceptible status.Considering this factors,,this paper on the basis of SIR model proposes a regression RSIR Botnet propagation model.The model description and mathematical formulas are given and analyzed.The actual data simulation shows that this model is effective.
