The new generation of information and communications technology is deeply integrated with the industrial system. The industrial Internet promotes the ubiquitous and deep interconnection and comprehensive perception of human, machines, and things. The industrial Internet equipment becomes increasingly networked, digital, and intelligent; therefore, the network security design, application management, and protection of these equipment become increasingly important. In this study, we clarify the connotation, protection scope, and requirements of the industrial Internet equipment, and summarize the development status of industrial Internet in China and abroad from the aspects of security control and security certification. Moreover, the problems regarding the network security of industrial Internet equipment in China are analyzed, and the specific implementation paths regarding the network security management and protection for the industrial internet equipment in China are discussed. Furthermore, several development suggestions are proposed. Specifically, the network security access mechanism of the industrial Internet equipment should be improved at the national level, a network security testing and certification system for the equipment should be established, research on the network security architecture and engineering application of the equipment should be promoted, and the network security risk monitoring and perception of the equipment should be strengthened.
