A Guide to an Internal ISO 27001 Audit: Checklist & Template

A Guide to an Internal ISO 27001 Audit: Checklist & Template
Published Nov 18, 2022

If you’re responsible for information systems within your organization, then you need to be aware of ISO 27001 – a global standard that specifies the requirements for an information security management system (ISMS) and helps to identify any information security risks.

An internal ISO 27001 audit is one way to ensure that your organization’s ISMS meets these requirements. And with our help, you’ll be able to audit for ISO 27001 and develop a treatment plan for your information security management system, all without even having to take an ISO 27001 internal audit course or class.

In this blog post, we will provide a comprehensive checklist and template that you can use to complete your own internal audit.

What is an ISO 27001 Audit?

An ISO 27001 audit is an assessment of your organization’s ISMS and its adherence to the standard’s requirements. It can be conducted by a third-party auditor, or the internal ISO 27001 audit process can be conducted by your own team.

Why Perform an ISO Audit 27001?

Regular ISO 27001 compliance audits are important for maintaining compliance with ISO 27001 and for identifying any gaps or weaknesses in your ISMS. Additionally, having strong procedures in place for conducting regular internal audits can demonstrate due diligence to external auditors.

How Do Internal ISO 27001 Audits and External Audits Differ?

ISO 27001 Internal audits are typically more hands-on and in-depth, as they are conducted by a team that is already familiar with the organization’s ISMS and has ISO 27001 internal audit training.

ISO 27001 External audits, on the other hand, provide an independent assessment from a third-party auditor who may have more objectivity and expertise in ISO 27001 audit requirements.

What is the Difference Between an ISO 27001 Stage 1 and Stage 2 Audit?

An ISO 27001 Stage 1 audit checklist is a preliminary assessment of your organization’s ISMS and its readiness for a Stage 2 audit. This typically involves reviewing documentation, conducting interviews with key personnel, and completing a gap analysis.

A Stage 2 audit is the detailed evaluation of your ISMS in action, including sample testing of controls.
