Abstract: By analyzing the typical structure of the municipal heating control system, the network security risks faced by the municipal heating control system are studied. According to the level protection requirements, a targeted security protection solution is proposed for the network security problem of the existing control system. The network security deep defense system of municipal heating control system is constructed based on area isolation, access authentication and network communication protection, software system security and centralized supervision. This solution of network security protection can be referenced in the municipal heating industry.
