With the development of the times,China's current technologies such as cloud computing and the Internet of Things have reached a relatively advanced level.These technologies are deeply integrated with industrial control system(ICS),which not only enhance the efficiency and quality of industrial control but also increase the complexity of cybersecurity protection.In this context,Zero Trust mechanism proposes a new solution for ICS cyber security protection,which is of practical significance to conduct in-depth research.This paper conducts in-depth research on ICS cyber security protection based on Zero Trust mechanism from two perspectives:the design of Zero Trust security framework and the construction of Zero Trust security defense system.
