关键基础设施网络安全技术研究进展

Research on network security of critical infrastructure: a survey

通过对关键基础设施的网络安全现状进行总结,对关键基础设施的安全威胁进行了分类,着重对信息物理融合系统在受到网络攻击时采用的数据词典、证据理论、博弈论等方法进行网络安全防护深入分析,着重分析了基于信任理论的信息物理融合系统的防御方案,阐述了关键基础设施的相关性与脆弱性之间的关系,总结了现有主要的关键基础设施网络安全的模拟技术,对比分析了现有的仿真技术的特点。最后提出了关键基础设施网络安全技术值得深入研究的发展方向。

This paper summarized the network security situation on critical infrastructure,it classified security threats to critical infrastructure. By focusing on the CPS in the network attack,it introduced the data dictionary,evidence theory,game theory analysis,the network security protection. It emphasized the analysis of the defense scheme cyber physical system based on the theory of trust,and studied the relation between the correlation and vulnerability of critical infrastructure. It summarized the network security simulation technologies of critical infrastructure present,and compared the simulation technologies. It put forward the future direction of development of critical infrastructure network security technology.
