چکیده انگلیسی:
Article history:Available online 30 June 2016Keywords:Smart gridSynchronous islanded generation STPACPSSafetyCyber securityCyber-physical systems tightly integrate physical processes and information and communication technolo- gies. As today’s critical infrastructures, e.g., the power grid or water distribution networks, are complex cyber-physical systems, ensuring their safety and security becomes of paramount importance. Traditional safety analysis methods, such as HAZOP, are ill-suited to assess these systems. Furthermore, cybersecu- rity vulnerabilities are often not considered critical, because their effects on the physical processes are not fully understood. In this work, we present STPA-SafeSec, a novel analysis methodology for both safety and security. Its results show the dependencies between cybersecurity vulnerabilities and system safety. Us- ing this information, the most effective mitigation strategies to ensure safety and security of the system can be readily identified. We apply STPA-SafeSec to a use case in the power grid domain, and highlight its benefits.© 2016 The Authors. Published by Elsevier Ltd. This is an open access article under the CC BY license.
