This PAS provides requirements and guidance for ensuring and assuring functional safety and security in different stages of the lifecycle. It will help the coordination of risk assessment, design and management and operation processes, avoiding conflicts between functional safety and security.

This specification does not aim to define a completely new lifecycle, but based on the functional safety lifecycle, security lifecycle and other state of the art engineering processes, it aims to provide requirements and suggestions to support coordination between functional safety and security.

The objective of this document is Industrial Automation Control Systems (IACS), including the Equipment Under Control (EUC) system and the safety-related system.
