Abstract: The paper gives a brief description about the current situation of industrial control network in the thermal industry, and a brief analysis of the risk of industrial control system. In view of the characteristics of industrial control systems such as heat exchanger stations. This paper provides the overall design of the overall security protection design according to the characteristics of industrial control networks in the thermal industry, and gives the design ideas from three aspects: defense in depth system, core industrial control system and centralized situation awareness, as well as the construction practice measures of security protection.

Key words: thermal industry, heat exchanger stations, industrial control system, industrial control network, security of industrial control system, defense in depth, situation awareness
