ISO 27001 Clause 5 Leadership Commitment: How to Audit It
Learn how to audit ISO 27001 Clause 5 leadership commitment with practical evidence for policy approval, roles, risk decisions, resources, management review, and certification readiness.
Quick Answer
How do you audit ISO 27001 Clause 5 leadership commitment?
To audit ISO 27001 Clause 5 leadership commitment, review whether top management actively supports the ISMS.
Check policy approval, role assignments, security objectives, risk decisions, management review, resource support, communication, and corrective action oversight.
The audit test is simple: can leadership prove accountability through decisions, records, owners, and follow-up actions?
A Signed Policy Is Not Enough
Leadership commitment is often misunderstood.
Many organizations think Clause 5 is complete because leadership signed the Information Security Policy.
That signature helps.
However, it does not always prove active leadership.
An internal audit should test whether leadership supports the ISMS through real decisions.
Practical rule: Clause 5 is not only about approval. It is about accountability.
The Main Clause 5 Audit Question
The strongest audit question is not, “Did leadership sign the policy?”
A better question is:
Can leadership show how they support, review, resource, and improve the ISMS?
Quick Clause 5 Audit Snapshot
| Clause 5 Area | What Internal Audit Should Test |
|---|---|
| Leadership Accountability | Does top management review ISMS performance and make decisions? |
| Policy Approval | Is the policy approved, current, communicated, and controlled? |
| Roles and Responsibilities | Are ISMS roles assigned, understood, and supported? |
| Resources | Does leadership provide people, budget, tools, and time? |
| Risk Decisions | Are risk acceptance and treatment decisions documented? |
| Management Review | Do minutes show decisions, owners, actions, and follow-up? |
What Strong Leadership Commitment Looks Like
Leadership commitment should appear in how the organization runs the ISMS.
What Weak Leadership Evidence Looks Like
Weak leadership commitment often shows up as missing decision evidence.
1. Audit Leadership Accountability
Top management does not need to perform every control.
However, leadership must ensure the ISMS is supported, reviewed, and aligned with the business.
Audit Questions
- Who is the executive sponsor?
- How does leadership review ISMS performance?
- How are security risks escalated?
- How are audit findings reviewed?
- How are overdue corrective actions escalated?
Practical rule: accountability should appear in decisions, not only in job titles.
2. Test Information Security Policy Approval
The Information Security Policy is important evidence.
Still, approval alone is not enough. The policy must be current, communicated, and controlled.
| What to Review | What It Proves |
|---|---|
| Approved policy. | Leadership approved the security direction. |
| Version history. | The current version is clear. |
| Communication record. | Employees were informed. |
| Review schedule. | The policy is maintained. |
3. Review Security Objectives
Leadership commitment should connect security to business goals.
Security objectives help leadership measure whether the ISMS is working.
Common finding: objectives exist, but they are not measured or reviewed by leadership.

4. Check Roles and Responsibilities
Leadership must ensure roles are assigned and understood.
The ISMS Manager may coordinate the system. However, control ownership should be shared across the business.
| ISMS Area | Typical Owner |
|---|---|
| ISMS Governance | Executive Sponsor or ISMS Manager. |
| Access Control | IT Manager. |
| Security Awareness | HR or ISMS Manager. |
| Vendor Risk | Operations, Procurement, or Security. |
| Contracts and DPAs | Legal. |
5. Test Resource Support
Leadership commitment should include resources.
Resources may include people, budget, tools, training, support, and time.
Evidence to Review
- Budget approvals.
- Resource planning records.
- Remediation plans.
- Training approvals.
- Tool approval records.
- Consultant or vCISO support records.
6. Review Risk Acceptance and Risk Decisions
Risk acceptance is a leadership issue.
Internal audit should test whether leadership formally reviews and accepts risk where needed.
Practical rule: leadership should not accept risk silently. Risk acceptance should be documented.
7. Review Management Review Evidence
Management review is strong Clause 5 evidence.
But the minutes must show more than attendance.
| Management Review Should Show | Why It Matters |
|---|---|
| Risk review. | Leadership understands the risk picture. |
| Audit results. | Leadership reviews findings and readiness. |
| Corrective actions. | Leadership tracks improvement. |
| Resource needs. | Leadership supports remediation. |
| Action owners. | Decisions lead to accountability. |
8. Interview Leadership
Internal audit should include leadership interviews.
The questions should be direct, practical, and evidence-based.
Interview Questions for Leadership
- Why is ISO 27001 important to the organization?
- What are the top information security risks today?
- How do you know the ISMS is working?
- How do you approve risk acceptance?
- How are corrective actions escalated?
- What improvements are planned for the next quarter?

|---|---|---|
| Policy approval missing. | Approve current version. | Create formal approval workflow. |
| Roles unclear. | Update owner matrix. | Communicate roles and confirm understanding. |
