本文根据博弈理论和Markov决策过程,研究了Markov博弈理论,并在其基上建立了基于Markov博弈理论的网络风险评估模型,将该评估模型用于安全态势评估与预测子系统中。给出了一个网络信息系统安全测试评估支撑平台,设计了其中的安全态评估与预测子系统的体系结构,并对其中用到的关键技术进行了详细设计,实现了安全态势评估系统。 Based on game theory and Markov decision process, this paper studies the Markov game theory and builds a network risk assessment model based on Markov game theory on its basis. This model is applied to the security situation assessment and prediction subsystem. A security testing and evaluation support platform for network information system is given, and the architecture of the security state evaluation and prediction subsystem is designed. The key technologies used in this system are designed in detail, and the security posture evaluation system is realized.
