集散控制系统(DCS)网络安全问题研究与建议

Research and Suggestions on Network Security Issues of Distributed Control Systems(DCS)

随着工业互联网的发展,工业控制系统不再是封闭的信息孤岛,面临网络安全威胁逐渐增多。集散控制系统DCS作为工业控制系统中最重要的控制系统之一,其安全性决定了整个工业控制系统的安全水平。为此,本文以艾默生的分散控制系统DeltaV DCS为研究对象,对其存在的安全问题进行分析,分别从操作系统漏洞、DeltaV安全漏洞、网络通信脆弱性、安全基线配置、供应链隐患等方面进行研究,研究出艾默生DeltaV DCS存在的安全隐患,并给出安全防护建议,对提升国家工业安全防护能力、促进工业信息安全产业发展等方面具有重要意义。

With the development of the industrial Internet,the industrial control system is no longer a closed information island,and faces increasing threats to network security.Distributed Control System(DCS)is one of the most important control systems in industrial control systems,and its security determines the security level of the entire industrial control system.For this reason,this paper takes Aimer DeltaV DCS as the research object,analyzes its existing security problems,and conducts research from the aspects of operating system vulnerabilities,DeltaV security vulnerabilities,network communication vulnerabilities,security baseline configuration,and hidden dangers in the supply chain.It is of great significance to improve the national industrial security protection ability and promote the development of industrial information security industry in the future by identifying the potential safety hazards of Emerson DeltaV DCS and giving safety protection suggestions.
