隨著控制系統復雜性的日益擴大，控制系統的網絡化是控制系統發展的必然。自動控制、計算機網絡和通訊技術的融合,為實現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，如何保障網絡控制系統的安全是當前控制網絡信息建設的研究熱點。文中通過分析網絡控制系統的結構和對網絡安全的要求,提出了將分布式入侵檢測技術運用到網絡控制系統的具體方案, 并對相關技術和網絡安全體系的建設進行了討論。

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.
