ISA/IECISA/IEC 62443IEC 62443: Risk Assessment & Asset Owner RequirementsEASYFree question
A green-field project team wants to embed IEC 62443-3-2 into design from the start. At what project phase does the standard intend the risk assessment to occur?
- A.During system design, so zones, conduits, and SL-T inform the architecture before build
- B.Only after the plant is fully operational
- C.Only during decommissioning
- D.Exclusively after a security incident
Why A is correct
IEC 62443-3-2 is explicitly a design-time activity; performing it during system design lets zones, conduits, and SL-T shape the architecture and procurement before construction. Deferring it until operation or after an incident loses the design influence.
