ISO/IEC 27005 FAQ ISO/IEC 27005 Review Cadence

Start with one decision record: scope, required inputs, owner, evidence location, and review condition. Then route the result to treatment or acceptance gates.

For ISO/IEC 27005, the useful record is practical: decision, scope, owner, evidence, exception, review trigger, and next action. This keeps the answer useful in audits, customer reviews, incidents, supplier reviews, and management review.

The evidence should show the process operating. For this artifact, the strongest record usually includes risk criteria, scenarios, likelihood and impact rationale, treatment decisions, residual-risk approvals, and review records.

Avoid evidence that only repeats a requirement. A reviewer should be able to see the actual owner, date, system, supplier, AI system, service, incident, risk, or control sample behind the answer.

The person who can fund, operate, and correct the process should own the decision; governance should review consistency and exceptions.

For high-impact changes, approval should include the teams affected by the evidence: security, privacy, resilience, supplier management, AI governance, legal, risk, or business service owners as relevant.

Review it on a planned schedule and on an ongoing basis, and update it whenever the underlying scope, service, supplier, control, risk, AI system, personal data flow, incident process, or customer commitment changes. NIST risk guidance says the useful life of assessment results is bounded in time, that organizations should determine how long results remain relevant, and that updates should be triggered by significant changes and incidents.

Set a planned review date and a change-trigger rule. If the facts change, update the evidence and mark what changed so the next reviewer can trust the page.
