Annex A 5.13
Labelling of information
Information carries labels reflecting its classification, in line with the scheme adopted.
What an assessor looks for
Show labelling in the formats you actually use, including email and collaboration tools rather than documents alone. Automated labelling needs evidence that it is applied and not merely available.
Where it usually fails
Labelling applies to formal documents while the majority of sensitive information moves through chat and email unlabelled.

Control number and title are identifiers used as references. The classification above is our own analysis, aligned to the shape of the ISO 27002 attribute model rather than reproduced from it, and no text from the standard appears on this page. Last reviewed 2026-08-03.
