Phase IV: ISO/IEC 27001 Internal Audit

After successfully completing all prior scoping, gap, and remediation phases, it is now time to perform an internal audit for ensuring your organization is ready to move forward with an actual ISO/IEC 27001 certification audit by an accredited certification body (CB). Simply stated, you need to perform an ISO/IEC 27001 “dry run’ prior to engaging and bringing on an actual CB for the ISO/IEC 27001 certification audit.

The internal audit gives you the chance to truly test your controls against all of the in-scope Annex A controls from ISO 27002:2022 that were documented in your Statement of Applicability (SoA). Therefore, if you have any nonconformities, now is the time to correct them before the auditors arrive!

Besides, an internal audit is a strict requirement, per the ISO/IEC 27001:2002 standard. Specifically, Per ISO/IEC 27001:2022 - Information security, cybersecurity, and privacy protection — Information security management systems — Requirements:

9.2 Internal audit
