- Write the alternate-site rules into remote-work policy: handling of printed CUI, device custody, who may be within view of the screen.
- Technical safeguards — full-disk encryption, VPN, session lock — carry much of the load; the physical rules cover what technology cannot, chiefly paper and shoulder surfing.
- Provide the means: people cannot lock documents away without lockable storage, and cannot avoid printing CUI at home without a workflow that makes printing unnecessary.
3.10.6 — Alternate work site safeguards
3.10 Physical Protection · NIST SP 800-171 Rev. 2 · The heading label is this site's navigational shorthand; the official language is the statement below.
Enforce safeguarding measures for CUI at alternate work sites.
NIST SP 800-171 Rev. 2 — Protecting CUI in Nonfederal Systems ↗NIST SP 800-171A — Assessing Security Requirements for CUI ↗What this requirement is after
CUI does not stop needing protection when work happens at a kitchen table or a hotel desk. The organization defines what safeguarding looks like at alternate work sites — locked storage for printouts, screens out of household view, encrypted devices, no shared family machines — and makes those enforceable expectations rather than suggestions.
Carried into Rev. 3 as 03.10.06 Alternate Work Site, substantially similar.
Brilliant at the Basics practices that support this requirement
The campaign’s twenty practices are a priority list, not a control catalog, and none of them works this requirement’s substance directly. It still applies to you if it is in your contract’s scope: address it through your own implementation and the related artifacts below, and treat the absence of a mapping here as honesty, not permission to skip it.
Implementation considerations and evidence
- The remote-work policy sections covering CUI at alternate sites
- Signed acknowledgments from personnel who work remotely with CUI
- Spot-check or self-attestation records showing the expectations operate
Templates and worksheets with a mapped relationship
