This paper introduces the background of Industrial 4.0 and through a comparison with the previous three industrial revolutions, emphasizing on the core idea which is put forward as the deep fusion of information systems and physical systems. Through the introduction of physical information fusion systems, we begin to analyze the interaction between the open interconnected network, its associated information along with the physical components, which makes the cyber-physics system face great security challenges. This paper presents research on Cyber Physics Department Security targets and the attack model of the unified system, giving an in-depth description about the security structure of layered information physical systems. The security of cyber physical system primarily exists to solve encryption technology in the case of malicious attacks, access control strategies, elastic mechanisms and so on. After introducing research relating to the cyber physical system security, key technologies such as the access control strategies and the privacy data protection mechanisms in the security layout of the cyber physical system are studied deeply. Finally, from the point of view of intelligent manufacturing, this paper analyzes the security problem of CPS, which has the characteristics of data-driven, software definition, ubiquitous connection, virtual reality mapping, heterogeneous integration and system autonomy, and should adopt the combination of "autonomy" and "common governance" to establish its security framework from the aspects of perception, transmission, computation, control and service. Also introduce the focus and direction of CPS research, such as blockchain.
