NIST 800-171 3.10.6 (PE.L2-3.10.6): Alternate Work Sites
Enforce safeguarding measures for CUI at alternate work sites.
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.
