3.10.6Cover work-from-home

Safeguards apply at alternate work sites, and you say what they are.

The requirement, verbatim

NIST SP 800-171 Rev. 2 · 3.10.6

Enforce safeguarding measures for CUI at alternate work sites.

Requirement 3.10.6, practice name in the CMMC assessment guide: Alternative Work Sites.

NIST's discussion

Alternate work sites may include government facilities or the private residences of employees. Organizations may define different security requirements for specific alternate work sites or types of sites depending on the work-related activities conducted at those sites.

NIST SP 800-46 and NIST SP 800-114 provide guidance on enterprise and user security when teleworking.

NIST SP 800-171 Rev. 2, discussion under 3.10.6. Whitespace normalised; wording unchanged.

Assessment objectives

An assessor decides each of these separately. The requirement is met only when every objective is.

  1. [a] safeguards for CUI are defined for alternate work sites
  2. [b] safeguards for CUI at alternate work sites are enforced

For assessors: examine, interview, test

NIST SP 800-171A names what an assessor may examine, whom they may interview, and what they may test for this requirement. Assessors select from these lists; they are not a checklist of everything you must produce.

Examine
  • Physical and environmental protection policy
  • procedures addressing alternate work sites for personnel
  • system security plan
  • list of safeguards required for alternate work sites
  • assessments of safeguards at alternate work sites
  • other relevant documents or records
Interview
  • Personnel approving use of alternate work sites
  • personnel using alternate work sites
  • personnel assessing controls at alternate work sites
  • personnel with information security responsibilities
Test
  • Organizational processes for security at alternate work sites
  • mechanisms supporting alternate work sites
  • safeguards employed at alternate work sites
  • means of communications between personnel at alternate work sites and security personnel

Evidence

No evidence examples are published for this requirement yet. The objectives above are what an assessor checks; evidence is whatever shows each one is true in your environment, dated and kept with your system security plan.

Scoring weight

Worth 1 point. Not meeting this requirement subtracts 1 from your 110-point SPRS score.

DoD NIST SP 800-171 Assessment Methodology v1.2.1 weighting, as carried in the Bedrock scoring table. The score starts at 110 and subtracts the weight of every requirement not met.

In Rev. 3

Rev. 2 is what your contract requires today. A standing DoD class deviation keeps Rev. 2 in force; NIST has published Rev. 3, but it is not adopted for contracts. In Rev. 3 this requirement is reworded: 03.10.06 Alternate Work Site. It gains organization-defined parameters.
