IEC 62443 for Risk Managers

What does IEC 62443 require of a Risk Manager?

Industrial Automation and Control Systems Security. Under IEC 62443, which defines 303 controls, a Risk Manager's work is deciding which controls you own outright, which you share and which belong to another team, then holding the evidence for the first group.

Which IEC 62443 controls land on the Risk Manager

Risk Managers identify, assess, and prioritise organisational risks. They build risk registers, conduct risk assessments, define risk appetite, and ensure that compliance frameworks address the most material threats to the organisation.

IEC 62443 defines 303 controls across 6 domains that directly affect the Risk Manager 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.
