In addition, the state's industrial support for domestic industrial control equipment needs to be strengthened. Especially in terms of system security, data security, application security, and security management system, the research investment needs to be further increased, professional and technical forces need to be cultivated and the research of core technologies need to be focused on. To solve the information security problem of industrial control systems has become one of the key topics that the industry pays close attention to. In this paper, the development history of industrial control system is introduced, the root cause of industrial control system security threats is deeply analyzed, the future security threats of industrial control system is pointed out and the safety precautions of industrial control system is put forward. Based on the analysis of this paper, the personal security awareness of the industrial control system can be raised and the challenges of security threats can be better solved.
