Survey and study on integration of safety and security in robot systems

초록

In this paper, research on the integration of safety and security in industrial systems, such as robots, automobiles, industrial automation systems, medical devices, and CPS(Cyber Physical System), has been reviewed and analyzed. Security issues are shown to affect the safety and performance in various industrial systems, and studies on integration of security and safety have been performed to solve this problem. In the field of robots, research related to security issues has been being performed but the types of security issues considered are very limited. This paper presents the vulnerabilities for cyber-attacks that can occur in robots by using examples, and the security countermeasures for these vulnerabilities are presented using the security requirements suggested by IEC 62443. Examples are presented to show that safety-related problems may occur even if some or all of these security requirements are satisfied in safety-related control devices. As methods to mitigate the safety and/or security countermeasures must also be taken very carefully, this paper presents an integrated risk assessment method for processing the safety and/or security issues and developing their proper countermeasures. © ICROS 2020.
