Question 1

How should teams handle Audit Evidence under ISO/IEC 27018?

Start with the operational decision: define what Audit Evidence means in your ISO/IEC 27018 scope, who owns it, and what record proves the decision is current.

For ISO/IEC 27018, 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.

  • Name the accountable owner and reviewer for Audit Evidence.
  • Record the scope, assumptions, decision, approval date, evidence location, exception status, and next review trigger.
  • Escalate when Audit Evidence changes risk acceptance, service commitments, customer promises, regulatory duties, or certification evidence.

Question 2

What evidence should prove Audit Evidence is current under ISO/IEC 27018?

The evidence should show the process operating. For this artifact, the strongest record usually includes customer instructions, DPA clauses, subprocessor notices, deletion and return records, disclosure records, access logs, and incident support evidence.

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.

  • Use source records from the system of work, not screenshots created only for audit day.
  • Keep exceptions visible as risk acceptance, corrective action, or management-review input.
  • Update linked registers when the answer changes an owner, risk, control, service, supplier, or review date.

Question 3

Who should approve Audit Evidence decisions under ISO/IEC 27018?

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.

  • Use a named owner, named backup, and named escalation forum.
  • Separate preparation work from risk acceptance and final approval.
  • Keep approval records with the evidence rather than in disconnected email threads.

Question 4

When should Audit Evidence be reviewed under ISO/IEC 27018?

Review it at planned intervals and whenever the underlying scope, service, supplier, control, risk, AI system, personal data flow, incident process, or customer commitment changes.

A stale record is worse than a short record. If the facts change, update the evidence and mark what changed so the next reviewer can trust the page.

  • Set a planned review date and a change-trigger rule.
  • Use findings to update controls, procedures, contracts, risk registers, or training.
  • Carry unresolved items into management review or risk acceptance.
