Information held in systems, devices or any other storage media is to be deleted once it is no longer needed. Purpose (stated in ISO/IEC 27002:2022): prevents unnecessary exposure of sensitive information and meets legal and contractual deletion requirements. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 8.10.
What evidence supports 8.10?
- Annex A technological controlStatement of Applicability entry for control A.8.10, showing inclusion or justified exclusion, implementation status and the risks it treats
- Annex A technological controlThe data retention topic-specific policy with deletion triggers per information type
- Annex A technological controlConfiguration of automated deletion after retention periods or on data subject requests
- Annex A technological controlDeletion logs or certificates as evidence, including from deletion service providers
- Annex A technological controlApproved secure deletion tools and methods matched to media type (overwriting, cryptographic erasure, degaussing)
Where this requirement comes from
This is our own statement of ISO 27001:2022 8.10, read from the copy we hold (licensed complete copy) and stated in our words, not the standard verbatim. The framework as we hold it.
Common gaps an assessor flags
- Information is deleted from the primary system but copies remain in backups, exports and temporary files
- No evidence of deletion is kept, so completion cannot be demonstrated
- Cloud providers' deletion methods are accepted without assessment
- Devices go back to vendors under warranty with drives still installed
How it maps to SOC 2
- C1.2 high Information deletion is the disposal requirement of this criterion.
- CC6.5 high Information deletion is the data removal step before protections are discontinued.
- P4.2 high Information deletion enforces that personal data is not retained indefinitely.
A link is a topical overlap with a confidence and a reason. It does not establish that meeting one requirement satisfies the other, and it is not certification.
