基于主机安全状态迁移模型的动态网络防御有效性评估

摘要

To evaluate the effectiveness of moving network defense,this paper presents the host security state deduce graph construction algorithm in moving network defense environment.The host security state transition model is constructed,the quantitative effectiveness evaluation method is proposed for moving network defense based on host state transition probability,and a useful reference is provided for the design of moving network defense policy.Finally,feasibility and effectiveness of the proposed model and method are illustrated and verified in a representative network example.%为了进行动态网络防御有效性评估,该文提出动态网络防御环境下的主机安全状态转移图生成算法,构建了主机安全状态迁移模型,基于状态转移概率给出了动态网络防御有效性的定量评估方法,为动态网络防御策略设计提供了有益参考.最后,通过一个典型网络实例说明和验证了上述模型和方法的可行性和有效性.
