摘　　要：工控系统越来越容易受到信息安全问题的威胁,如计算机病毒、网络病毒、数据操纵,这些威胁会对整个工控系统造成破坏。分析了工控系统信息安全问题及其对控制性能和控制功能的破坏,指出了工业控制系统仍存在的潜在脆弱点,并提出了相应的对策。这些对策包括裁减操作系统、工控用分布式防火墙技术应用以及工控系统安全风险评估。对工业控制系统的信息安全性进行分析,将有助于信息技术在工业控制系统中的应用。The industrial control system is increasingly easy to be threatened by information security issues such as computer or network viruses and data manipulation which may destroy entire control system. The information security of industrial control system and its influence on control performance and functions are analyzed. Other potential vulnerabilities existing in industrial control system are also proposed , and corresponding countermeasures are given. These measures include tailoring the operating system , applying distributed firewall technology for industrial control, and assessing the safety risk for industrial control system. The analysis of information security for industrial control system is helpful to the application of information technology in industrial control system.
