When does a page need an Annex A Control Owner and what does ownership mean?
Assign a named owner for each Annex A control that is included in your ISMS scope so responsibility for operation and implementation decisions remains traceable over time.
An owner should validate that the control remains aligned with scope, risk treatment choices, and business-service changes before records are finalized.
- Define ownership in your SoA/control register at the same granularity as your control evidence (per control row).
- Assign owner roles that match your internal model (security, infrastructure, platform, application, and shared-service ownership patterns).
- Keep role updates explicit when teams, systems, or service boundaries move.
