工控系统信息安全的网络防护技术研究

Research on Network Protection Technology of Industrial Control System Information Security

工控系统是利用现场总线实现对其他工业系统的控制,完成控制器间的通信工作,进而实现工业系统的完整互通。工控系统信息安全网络防护尤为重要,防护技术的研究与应用,对工控系统的正常运转以及安全性具有重大影响。部分工业企业控制系统中,一些安全问题存在一定的隐蔽性,稍有差池就会引起整个工控网络的安全故障问题,进而影响整个系统功能的稳定性。对工控系统信息安全的相关网络防护内容开展研究,探究了网络防护技术的研发与应用,以期保证工控系统的安全运行。

Industrial control system usesfield bus to realize the control of other industrial systems,complete the communication between controllers,and then realize the complete intercommunication of industrial systems.At this time,information security network protection is particularly important.The research and application of protection technology has a great impact on the normal operation and security of industrial control system.In some industrial enterprise control systems,there is a certain degree of concealment.A slight difference will cause the safety failure of the entire industrial control network,and then affect the stability of the entire system function.Based on the research of the related network protection content of the information security of the industrial control system,this paper analyzes the research and development and application of the network protection technology,in order to ensure the safe operation of the industrial control system.
