What this control covers
Schedule, document, and review Maintenance, repair, and replacement of system components per vendor or organizational requirements, including equipment sanitization and off-site activity approval. This control supports the System Maintenance capability within the Maintenance family.
Why it matters
Risk is the language an executive team understands; this control connects technical reality to board-level decisions and budget allocation.
How to implement
AWS
Codify the policy intent as SCPs, AWS Config conformance packs, and Security Hub standards so the cloud enforces what the document says.
Azure
Codify in Azure Policy initiatives (built-in regulatory compliance for CIS, ISO 27001, SOC 2, HIPAA) and assign at management-group level.
On-premises
Maintain a policy library with a documented review cadence (annual minimum); store in your GRC tool with attestation tracking. Map each policy to controls so an audit pull cites the exact policy clause.
