Episode 21 — Clause 9.2 — Internal audit
Clause 9.2 establishes the internal audit as a formal, independent check on ISMS conformity and effectiveness. For the exam, remember that audits must be planned, implemented, and maintained with defined criteria, scope, frequency, and methods, and auditors must be objective and impartial. The purpose is not only to find nonconformities but to evaluate whether processes are producing intended outcomes and whether the management system aligns with ISO 27001 requirements and the organization’s own policies. A defensible audit program is risk-based, integrates with PDCA, and provides management with reliable evidence for decisions, making it a cornerstone of continual improvement and certification readiness.
Effective programs start with a multi-year audit plan aligned to risk, change, and previous findings. Auditors prepare checklists that trace from clauses and the Statement of Applicability to documented procedures and sampled records, then conduct interviews and tests of control operation. Common pitfalls include auditing only documentation, recycling the same checklists without adapting to changes, and allowing conflicts of interest when process owners audit their own work. Best practice includes clear nonconformity grading, concise evidence logs, root cause analysis expectations, and time-bound corrective actions tracked to closure. Candidates should be ready to explain how internal audit results flow into management review, how sampling strategies are justified, and how audit trails support reproducibility and consistency across cycles.
