ISO 27043 for CISOs

What does ISO 27043 require of a CISO?

Incident investigation principles and processes. Under ISO 27043, which defines 37 controls, a CISO'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 ISO 27043 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.

ISO 27043 defines 37 controls across 8 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.
