IEC 62443 for Auditors
What does IEC 62443 require of a Auditor?
Internal Auditors assess whether compliance controls are operating effectively. Under IEC 62443, which defines 81 controls, the work that lands on a Auditor is deciding which controls you own outright, which you share, and which belong to another team, then holding evidence for the first group.
Which IEC 62443 controls land on the Auditor
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 81 controls across 11 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.
