ISO 27001 Annex A 5.13: Labelling of information

What auditors look for

Auditors check that 5.13 is either justified as not applicable in your Statement of Applicability or implemented and working. Typical evidence includes:

• Labelling procedure
• Document templates with labels
• Automatic labelling configuration where used

How to implement 5.13 in practice

1. Automate labels in email and document tools where possible
2. Keep manual labelling simple
3. Explain labels in training
4. Name an owner for 5.13, decide how often it runs and file evidence each time, so the control is audit-ready all year.

Recording 5.13 in the Statement of Applicability

List 5.13 with whether it applies, the reason (usually the risks it treats or a legal or contractual requirement), its implementation status and where the evidence lives. If you exclude it, explain why none of your risks or obligations require it.
