IEC 62443 for Auditors
Internal Auditors assess whether compliance controls are operating effectively. This guide covers how IEC 62443 impacts the Auditor role, key responsibilities, common challenges, and practical tools for success.
How IEC 62443 Impacts Auditors
Internal Auditors assess whether compliance controls are operating effectively. They plan and execute audit engagements, evaluate evidence, report findings, and track remediation of identified gaps and nonconformities.
IEC 62443 defines 24 controls across 5 domains that directly affect the Auditor role. Understanding which controls fall within your ownership, which are shared, and which are owned by other teams is the foundation of effective compliance management.
