Investigation study of Cyber-Physical Systems: Characteristics, application domains, and security challenges

Cyber-Physical Systems (CPSs) are currently widely used in people's daily lives but present risks and threats, especially when used by cybercriminals against the governments, corporations, organizations, or individuals. CPS applications are increasingly becoming attractive and are targeted by cyber-attacks. Tools and theories that can be used by organizations and researchers to understand the types of new threats and the impacts that each threat can cause to the physical systems are lacking at present. In this research, current physical security threats of CPSs for the last few years are investigated to briefly describe the usage, application domains, and security challenges of CPSs in their field of application. This work serves a basis for further studies on cyber physical security.
