ISO 27001 Clause 9.2: How to Plan and Run a Smart Internal Audit

Clause 9.2 of ISO 27001: Internal Audits That Actually Add Value

From Audit Planning to Execution — The Practical Way

Internal Audits Done Right

Clause 9.2 Isn’t About Catching Mistakes — It’s About Making Improvements

Too many organizations treat internal audits like a necessary evil — a dry checklist that’s run once a year just to satisfy the ISO 27001 auditor.

But Clause 9.2 was never meant to be that shallow.

It’s a powerful tool to keep your ISMS relevant, sharp, and truly effective.

What Clause 9.2 Requires

Clause 9.2 lays out four key expectations:

1. You must conduct internal audits at planned intervals
2. Audits should determine whether your ISMS conforms to:
3. You need to plan the audit program based on importance and changes
4. You must keep records of audit results and corrective actions

Simple in theory — but the execution is what makes it powerful.

How to Plan an Internal Audit That Works

Here’s what an effective internal audit program under Clause 9.2 looks like:

• Risk-based schedule: High-risk areas audited more frequently
• Defined scope: Audits tied to specific controls or departments
• Objective auditors: Not auditing their own work
• Clear criteria: Based on your ISMS and Annex A controls
• Real findings: Not just “no nonconformities” every time
• Follow-through: Findings lead to action, not just documentation

Common Mistakes to Avoid

• Using the same generic checklist every year
• Not updating the audit scope to match ISMS changes
• Skipping areas that “look fine”
• Focusing only on documentation, not control effectiveness
• Not involving process owners or stakeholders
• Not linking audit results to continual improvement

A Fun Fact

The word "audit" comes from the Latin audire — to hear. Originally, audits were oral checks of financial honesty. Now, they’re your ISMS’s reality check.

What Auditors Want to See (Clause 9.2 Specifics)

• Documented audit plan (with scope, criteria, frequency)
• Audit reports with findings clearly linked to controls
• Evidence of internal audits being done periodically
• Corrective actions tracked and closed
• Improvement insights — not just lists of issues

How Often Should You Audit Internally?

There’s no fixed rule — it depends on:

• The size of your org
• Complexity of your ISMS
• Changes to systems/processes
• Outcomes of previous audits

Tip: Don’t wait for 12 months. Spread audits out quarterly or by domain.
