Importance of Functional Safety and Security

Functional safety and security are critical components in the design and operation of IACS. Functional safety ensures that systems operate correctly in response to inputs, including the safe management of potential failures. Security, on the other hand, protects systems from unauthorized access and cyber threats. The integration of these two elements is crucial for the reliable and safe operation of industrial systems.

Lifecycle Approach

The lifecycle approach outlined in the PD IEC PAS 63325:2020 standard provides a structured methodology for managing safety and security throughout the entire lifecycle of an IACS. This includes the initial design phase, implementation, operation, maintenance, and eventual decommissioning. By following this approach, organizations can ensure that safety and security are considered at every stage, reducing risks and enhancing system reliability.
