Governments, enterprises and research institutions have participated the research and development of cyber-physical systems (CPS). However, the development of cyber-physical systems will be restricted by security threats and vulnerabilities. We summarize security threats and to the cyber-physical systems to provide a theoretical reference for research on cyber-physical systems and to provide effective security measures. The architecture of cyber-physical systems is used to classify threats in the physical layer, network layer and application layer. This paper presents the security threats in the three layers. Then it lists the vulnerabilities of cyber-physical systems from the three aspects of management and policy, platform and network. Correspondingly, it also provides some security measures and recommendations for the security threats and vulnerabilities in each section.
