云计算环境下的病毒传播模型研究

Research on the Virus Spreading Model in Cloud Computing Environment

云安全体系的出现,使得计算机病毒的传播有一定的新特点,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,提出了一种基于传统的SEIR模型的病毒传播模型(SEIR_C).SEIR_C模型在考虑潜伏的计算机病毒以更强控制病毒传播的基础上,加入了用户是否参加了云安全计划的这一属性,越多的成员上报越多的病毒信息,那么就可能更快更准确地分析得出病毒特征加以遏制.

With the emergence of cloud security system makes the spread of computer viruses possess some new features, and the focus of virus detection and prevention has shifted from client to the network and the backend server group. For the cloud security system environment, a virus spread model based on traditional SEIR model was proposed in the paper. In addition to the control of the spread of the virus, the attribute of whether users join in cloud security plan was added in the model considering the traditional latent virus. The more virus information is submitted to the cloud, the faster and more accurately the model will analyze the features of viruses.
