IEC PAS 63325:2020 provides requirements and guidance on the ensurance and assurance of functional safety and security in different stages of the lifecycle. It will help to coordinate risk assessment, design and management and operation processes, avoiding conflicts between functional safety and security.
This PAS does not aim to give some 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 in some typical stages to achieve coordination between functional safety and security.
The objective of this PAS is Industry Automation Control System (IACS), including Equipment Under Control (EUC) system and safety-related system.
