操作系统病毒传播模型及混合防御策略
An Operating System Virus Propagation Model and Hybrid Defense Strategy
摘要
Abstract
Aimed at the problems that user's business is different in demand for partiality and single de-fense strategy is limited in real network services,a virus propagation model and mixed defense strategy is proposed in operating system.First of all,the network is split into different subnets by adopting link in-terrupt and operating system migration strategies.In synthetic consideration of the correlation of the virus infection between subnets and virus propagation,an operating system virus propagation model is construc-ted,and the equilibrium solution and the stability analysis of the system are given.Secondly,by introdu-cing the network service evaluation index and the definition of negative cost,a hybrid defense strategy is proposed to suppress the spread of operating system virus.The calculation method of optimal policy con-figuration,execution process and parameter identification algorithm are designed.The theoretical and ex-perimental results show that the proposed virus propagation model and the hybrid defense strategy can ef-fectively supplement the gap period of the traditional defense means in short supply.关键词
