Abstract
This article addresses integrated functional safety and cybersecurity analysis with regard to: the generic functional safety standard IEC 61508 and the cyber security standard IEC 62443 concerning an industrial automation and control system (IACS). The objective is to mitigate the vulnerability of information technology (IT) and operational technology (OT) systems, and reduce relevant risks taking into account a set of fundamental requirements (FRs). A method is proposed for determining and verifying the performance level (PL) or the safety integrity level (SIL) of defined safety functions, and then validating these levels depending on the security level (SL) of a particular domain, e.g. a safety related control system (SRCS). The method is general in the sense that it is based on risk graphs prepared for individual risk and/or societal/group risk with regard to the criteria defined.
