Audit Follow-Up and Verification
Overview
Audit follow-up is the process by which the audit function monitors and verifies that management has effectively implemented remediation actions in response to audit findings. IIA Standard 2500 requires the Chief Audit Executive to establish and maintain a system to monitor the disposition of results communicated to management. Follow-up is not merely tracking whether actions were completed — it requires independent verification that the remediation actually addresses the root cause and reduces the identified risk to an acceptable level.
In privacy audits, effective follow-up is critical because unremediated findings represent ongoing regulatory non-compliance. A GDPR Art. 5(2) accountability failure, an unpatched consent mechanism, or a persistent DSAR processing delay exposes the organization to supervisory authority enforcement, data subject complaints, and reputational harm.
Follow-Up Scheduling
Follow-up timing is driven by finding severity:
| Severity | Initial Follow-Up | Re-test if Partial | Maximum Extensions |
|---|---|---|---|
| Critical | 30 days after target date | 15 days | 1 (requires CPO approval) |
| High | 60 days after target date | 30 days | 2 (requires DPO approval) |
| Medium | 90 days after target date | 45 days | 2 |
| Low | 180 days after target date | 90 days | 3 |
| Advisory | Next scheduled audit | N/A | N/A |
