水利工控系统网络安全防护的问题与对策

近年来工控网络安全事件频繁发生,并且呈逐年递增趋势,造成的安全事件影响越来越大,甚至逐步威胁到国家安全。水利工程是国家关键基础设施的重要组成部分。随着"中国制造2025"和两化融合工作的推进,越来越多的智能设备、计算机技术和网络技术应用于工业控制系统,使工业控制系统极易遭到来自管理网或互联网病毒、木马以及黑客的攻击。文中主要介绍了水利工控网络安全的现状、在技术和管理方面存在的主要问题,以及引起水利工控网络安全问题的主要原因,重点阐述了水利工控系统网络安全防护工作要点及安全防护方案,并以水电厂工控系统为例给出了具体的防护措施。

Problems and countermeasures of cybersecurity on industrial control systems in water projects

In recent years, industrial control network security incidents have happened frequently, and in-creased year by year. The impact of security incidents is more and more serious, which even threatens na-tional security gradually. Water projects are an important part of the national key infrastructure. With the development of "China made 2025" and "two integration", more and more intelligent equipment, comput-er technology and network technology are applied to industrial control system, which make the industrial control system vulnerable to management network, Internet virus, Trojan horse and hacker. This paper intro-duces the main problems existing in the aspects of technology and management status, and the main cause of water industrial network security problems, focusing on the protection and safety of water work points of industrial control system network and security solutions, and with the control system of water power plant as an example gives the specific protection measures.
