9.2.1 Internal audit: general
Internal audits must be carried out at planned intervals to give information on whether the ISMS conforms to the organization's own ISMS requirements and to this standard, and whether it is effectively implemented and maintained.
Source: ISO/IEC 27001:2022, 9.2.1. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open ISO/IEC 27001:2022 in the compliance library.
Clauses 4 to 10 are the management-system requirements: none of them can be excluded when an organisation claims conformity. The 93 Annex A controls are a reference set: one may be excluded with a justification in the Statement of Applicability. Certification bodies assess conformity; the evidence lists here are what auditors commonly ask for, not a list the standard prescribes.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Audits check documents only, not implementation
- Parts of the ISMS are never audited
- Audits are not carried out at the planned intervals
- Audits test against the standard but not the organization's own requirements
