# NIST 800-171 3.7.3 (MA.L2-3.7.3): Off-Site Maintenance

NIST 800-171 / Maintenance / 3.7.3

"Ensure equipment removed for off-site maintenance is sanitized of any CUI." ([NIST SP 800-171 Rev. 2, requirement 3.7.3](https://doi.org/10.6028/NIST.SP.800-171r2))

CMMC Level 2 practice MA.L2-3.7.3.

## What 3.7.3 means in practice

Before a laptop, server, drive or copier leaves for repair elsewhere, any CUI on it is removed, or its storage is pulled and kept. Follow a sanitization method such as NIST SP 800-88 and keep a record for each item.

## SPRS points and the CMMC POA&M

- **CMMC Level 2 practice**: MA.L2-3.7.3
- **SPRS points**: 1 point. When it is not met, the DoD Assessment Methodology subtracts 1 from the score of 110.
- **CMMC POA&M**: Allowed. It is worth 1 point, and 32 CFR 170.21(a)(2)(ii) admits requirements worth 1 point. Conditional status also needs a score of at least 88, and the item must be closed within 180 days.
