Use this FAQ as a practical internal-audit workflow: define scope, assign accountable roles, collect auditable evidence, and close non-conformities with traceable decisions. Use this FAQ to execute and document internal audits in your ISMS: define what is being audited, keep evidence review-ready, and route findings to governance for closure. ## What must happen before, during, and after an internal audit? ISO/IEC 27001 internal audits should be planned, documented, and executed to confirm alignment between your ISMS and both your own requirements and standard requirements. Before the audit, define scope (processes, systems, suppliers, locations), sample criteria, and owners; during the audit, verify conformance and implementation; after the audit, track issues, decisions, and corrective actions. - Create an audit program with objective and interval (for example annual or risk-based with additional audits after major changes). - Map each audit area to who can review what: preparer, evidence owner, independent reviewer, and approver. - Do not let process builders validate their own findings.

Evidence should show what was tested, how it was tested, who tested it, and the result. Show outcomes at a level that can be independently validated later, including issue IDs, test samples, and proof of closure timing. - Attach a control-level audit checklist and schedule from your ISMS scope. - Keep test artifacts, interview notes, log extracts, and issue tracking entries together with timestamps. - Record findings with severity, exception rationale, corrective action owner, and target close date. Sources for this answer: - [ISO/IEC 27002:2022 standard page](https://www.iso.org/standard/75652.html?ref=sorena.io) - Use this source to anchor audit checks where control implementation evidence is required. - [ISO/IEC 27001 Lead Auditor Guideline](https://www.iso.org/standard/27001?ref=sorena.io) - This source supports documented information requirements around findings, corrective action, and independent audit activity. ## Who should review and approve internal-audit findings? Assign a non-authoring reviewer to validate findings before closure. Escalate anything that affects scope, customer commitments, or recurring non-conformities to governance for risk-based approval. Close findings only when correction evidence is available and verified. - Record each finding with owner, risk impact, decision date, and remediation proof. - Separate independent audit team responsibilities from implementation ownership. - Require management-review visibility for unresolved major findings.

Re-check internal-audit outputs at planned intervals and when triggers indicate evidence may be stale. If control context changes, supplier ownership changes, or prior findings remain open, rerun impacted audit areas before relying on prior conclusions. - Use calendar review dates plus change-trigger reviews for incidents, context shifts, or contractual scope changes. - Re-verify closed findings after remediation evidence is produced, not after the target date alone. - Track all unresolved findings in governance to prevent drift between audit cycles.
