在役工业控制系统的信息安全检查与加固

Inspection and Reinforcement of Information Security of the ICS in Service

通过对当前工业控制系统网络信息安全现状的分析,探讨了工业控制系统滞后的运行环境以及难以实施的更新问题,从而导致的工业控制系统较之传统信息系统更为严峻的网络安全隐患,采用网络数据流量异常监测和部署虚拟网关产生报警的方法,对某典型工业控制系统的网络信息安全实施检测,提出了一个实用可靠的网络安全加固方案并加以实现。

Based on the analysis of the current status of network information security of industrial control system,the hysteretic operation environment and the difficulty to implement the upgrade for industrial control systems are discussed,the network security threat of industrial control system is worse than that for traditional information system.With application the method of monitoring abnormal network data flow and deploying virtual gateway to generate alarm,the network information security inspection is carried out for one industrial control system.A practical and reliable network security reinforcement scheme is put forward and implemented.
