云安全体系的出现标志着病毒检测和防御的重心从用户端向网络和后台服务器群转变,针对云安全体系环境,基于经典SIR模型提出了一种新的病毒传播模型(SIR_C)。SIR_C在考虑传统防御措施以及蠕虫造成的网络拥塞流量对自身传播遏制作用的基础上,重点分析了网络中云安全的部署程度和信息收集能力对蠕虫传播模型的影响。实验证明SIR_C模型是蠕虫传播研究在云安全环境下有意义的尝试。
The emergence of cloud security changed the major virus-defensive position from client to network and server group.From the view of the cloud security,a novel worm propagation model,SIR_C(SIR in cloud security),which drives from SIR model was proposed.Based on considering the traditional human countermeasures and the network congestion traffic which is caused by worms and will curb the spread of worms,SIR_C model focused on the analysis of the impact of the degree of cloud security deployment and the information gathering capability on worm propagation model.The simula-tion results show that SIR_C model was a meaningful attempt to research worm epidemics in cloud security network.
