隨著控制系統(tǒng)復(fù)雜性的日益擴(kuò)大，控制系統(tǒng)的網(wǎng)絡(luò)化是控制系統(tǒng)發(fā)展的必然。自動(dòng)控制、計(jì)算機(jī)網(wǎng)絡(luò)和通訊技術(shù)的融合,為實(shí)現(xiàn)控制和管理信息一體化提供了一條新思路，但也帶來以一系列安全問題，如何保障網(wǎng)絡(luò)控制系統(tǒng)的安全是當(dāng)前控制網(wǎng)絡(luò)信息建設(shè)的研究熱點(diǎn)。文中通過分析網(wǎng)絡(luò)控制系統(tǒng)的結(jié)構(gòu)和對(duì)網(wǎng)絡(luò)安全的要求,提出了將分布式入侵檢測技術(shù)運(yùn)用到網(wǎng)絡(luò)控制系統(tǒng)的具體方案, 并對(duì)相關(guān)技術(shù)和網(wǎng)絡(luò)安全體系的建設(shè)進(jìn)行了討論。

Abstract: Following the enlargement of control system’s complexity, Networking is a trend of control system development. The fusion of control, computer network and communication technologies provide a new idea for the integration of control and management information system, but it also results in a series security problems. How to guarantee the security of the networked control system is a hot spot in the study of control network. The networked control system structure and its requirements on the network safety are expounded. A
detailed project for the application of distributed intrusion detection technology in the networked control system is proposed. Associated techniques and the development of the network security system are discussed.
