# NIST 800-171 3.10.6 (PE.L2-3.10.6): Alternate Work Sites

NIST 800-171 / Physical Protection / 3.10.6

"Enforce safeguarding measures for CUI at alternate work sites." ([NIST SP 800-171 Rev. 2, requirement 3.10.6](https://doi.org/10.6028/NIST.SP.800-171r2))

CMMC Level 2 practice PE.L2-3.10.6.

## What 3.10.6 means in practice

When people work with CUI at home or at another site, the protections follow them. Define the safeguards for alternate work sites, such as a managed device, an encrypted connection, a private workspace and no printing of CUI, and check that they are applied.

## SPRS points and the CMMC POA&M

- **CMMC Level 2 practice**: PE.L2-3.10.6
- **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.

## What an assessor checks for 3.10.6

NIST SP 800-171A gives 2 determination statements for 3.10.6, each found satisfied or other than satisfied. Determine if:

- 3.10.6[a] safeguarding measures for CUI are defined for alternate work sites.
- 3.10.6[b] safeguarding measures for CUI are enforced for alternate work sites.

[NIST SP 800-171A (June 2018), assessment objectives for 3.10.6](https://doi.org/10.6028/NIST.SP.800-171A)

## Evidence that shows 3.10.6 is met

- The telework or alternate work site policy listing the required safeguards.
- Signed telework agreements.
- Device and connection settings enforced on remote workers' devices.
