Official Requirement
Ensure equipment removed for off-site maintenance is sanitized of any CUI.
What This Means in Plain English
Before sending any hardware out for repair or maintenance, all CUI must be removed from it. If the equipment cannot be sanitized, it must be physically escorted or the maintenance must be performed on-site by cleared personnel.
How Petronella Implements This Control
Petronella Technology Group implements this control through:
- Data sanitization procedures using NIST 800-88 guidelines before any equipment leaves the facility
- Full disk wipe using approved tools for any storage media sent for repair
- Swap-and-replace approach keeping CUI-containing storage on-site while sending only non-storage components for repair
- Chain of custody documentation for all equipment sent off-site
- ComplianceArmor tracking equipment sanitization and off-site maintenance records
Assessment Guidance
Assessors will review data sanitization procedures, verify that equipment removal is logged with sanitization records, check that chain of custody documentation exists, and confirm that storage media is retained when equipment is sent for off-site repair.
Common Implementation Gaps
- Equipment sent for repair without sanitizing CUI
- No data sanitization procedure documented
- Hard drives sent with equipment to third-party repair
- No chain of custody for equipment leaving the facility
- No tracking of equipment sent for off-site maintenance
