Joint safety and security risk analysis in industrial cyber-physical systems: A survey

Industrial Cyber-Physical Systems (iCPSs) represent a new generation of industrial systems that enable a profound integration of industrial processes and informational spaces, thereby empowering the fourth industrial revolution. iCPSs confront more severe safety and security (S&S) challenges compared to traditional industrial systems. One of the most critical challenges is the joint risk analysis of S&S. Many scholars have devoted their research to this area. However, there is a dearth of literature reviews encapsulating recent advancements, which provides the motivation for this study. The authors review the methodologies in this field, delve into the S&S relationships involved, and propose 12 criteria for evaluating these methods. Furthermore, the current research limitations were analysed and potential directions were suggested for future research.
