Require that organization-defined personnel or roles explicitly approve the removal of the system or system components from organizational facilities for off-site maintenance, repair, or replacement; d. Sanitize equipment to remove the following information from associated media prior to removal from organizational facilities for off-site maintenance, repair, or replacement: organization-defined information; e.

Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
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.

- Components removed for off-site repair were not sanitized of the organization-defined information beforehand, contrary to d
