IEC 62443 readiness guide for control system projects
A practical guide to SuC definition, zones and conduits, security level discussions, supplier requirements and verification evidence.

Define the system under consideration
IEC 62443-aligned work needs a clear system under consideration before requirements can be interpreted sensibly. The SuC should identify the control system boundary, external interfaces, supplier packages and operational assumptions.
Without this definition, projects can spend time debating compliance without knowing which assets, conduits or responsibilities are being assessed.
Translate requirements into engineering deliverables
Project teams usually need drawings, matrices, review comments, test records and handover evidence rather than abstract statements of alignment.
The readiness activity should make clear which evidence will be produced during design, FAT, SAT and close-out.
Useful evidence
- SuC definition
- zone and conduit model
- requirements and evidence matrix
- supplier cybersecurity requirement review
- verification and close-out plan
