What is an internal audit?
Internal audits are a mandatory requirement within ISO 27001, but they are also an important way to verify that your Information Security Management system (ISMS) is functioning as required and to identify opportunities for improvement.
Whilst internal auditing will be new businesses without existing certifications, they are actually more straightforward and valuable than you might think.
The ISO 27001 internal audit requirement
The requirement is that an organisation will conduct internal audits against all clauses and controls of the iso 27001 standard over the three-year certification cycle.
The audits should be run according to a documented schedule that prioritises high-risk areas, and with the assumption that no less than two internal audits will have been completed and documented ahead of the Stage 2 certification assessment.
