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.
