IEC 62443 for CISOs

What does IEC 62443 require of a CISO?

CISOs own the organisation's information security strategy, budget, and risk posture. Under IEC 62443, which defines 81 controls, the work that lands on a CISO 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 CISO

CISOs own the organisation's information security strategy, budget, and risk posture. They translate compliance requirements into security programmes, report to the board, and balance security investment against business objectives.

IEC 62443 defines 81 controls across 11 domains that directly affect the CISO 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.
