The chapter is devoted some important issues of the functional safety analysis, in particular the safety integrity level (SIL) verification of safety functions to be implemented within the distributed control and protection systems with regard to security aspects. A method based on quantitative and qualitative information is proposed for the SIL (IEC 61508, 61511) verification with regard of the evaluation assurance levels (EAL) (ISO/IEC 15408), the security assurance levels (SAL) (IEC 62443), and the number of protection rings described in the Secure Safety (SeSa-SINTEF) methodology. The proposed approach will be composed of the following items: process and procedure based safety and security management, integrated safety and security assessment of industrial control system (ICS) of the critical infrastructure.
