Abstract
This chapter addresses some of the issues of the integrated functional safety and cybersecurity analysis and management with regard to selected references and the functional safety standards: IEC 61508, IEC 61511, ISO 13849-1 and IEC 62061, and a cybersecurity standard IEC 62443 that concerns the industrial automation and control systems. The objective is to mitigate the vulnerability of industrial systems that include the information technology (IT) and operational technology (OT) to reduce relevant risks. An approach is proposed for verifying the performance level (PL) or the safety integrity level (SIL) of defined safety function, and then to check the level obtained taking into account the security assurance level (SAL) of particular domain, for example, a safety-related control system (SRCS), in which the given safety function is to be implemented. The SAL is determined based on a vector of fundamental requirements (FRs). The method uses defined risk graphs for the individual and/or the societal risk, and relevant risk criteria, for determining the performance level required PLr or the safety integrity level claimed SIL CL, and probabilistic models to verify PL/SIL achievable for the architecture of the SRCS considered.
