# NIST 800-171 3.7.6 (MA.L2-3.7.6): Maintenance Personnel

NIST 800-171 / Maintenance / 3.7.6

"Supervise the maintenance activities of maintenance personnel without required access authorization." ([NIST SP 800-171 Rev. 2, requirement 3.7.6](https://doi.org/10.6028/NIST.SP.800-171r2))

CMMC Level 2 practice MA.L2-3.7.6.

## What 3.7.6 means in practice

When someone without authorized access, such as a vendor technician, works on the system, an authorized employee supervises them for the whole visit. Record who was supervised, by whom and when.

## SPRS points and the CMMC POA&M

- **CMMC Level 2 practice**: MA.L2-3.7.6
- **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.
