What you will be able to do
- Describe the purpose and scope of NIST SP 800-171 for non-federal systems.
- List the major requirement families covered by the standard.
- Explain how to scope a system boundary before working through requirements.
- Recognize the requirement areas where small businesses commonly struggle.
- Draft a one-paragraph implementation narrative for a given requirement.
What it is
A published set of security requirements for protecting CUI when it lives on systems you own rather than government systems. It is organized into families covering access, awareness, audit, configuration, identification, incident response, maintenance, media, personnel, physical, risk, assessment, systems and communications protection, and system integrity.
How to approach it
- Scope honestly — the smaller and clearer the boundary, the less work.
- Work family by family and write a one-paragraph narrative per requirement.
- Track what is not done in a POA&M rather than leaving blanks.
Where small businesses get stuck
- Audit logging: collecting logs is easy, reviewing them is the requirement.
- Configuration baselines: writing down the standard build people forget they have.
- Media and mobile: removable drives and personal devices used quietly.
Key takeaways
- NIST SP 800-171 governs protecting CUI on systems a contractor owns, rather than on government-operated systems.
- The standard is organized into requirement families spanning access control, audit, incident response, and more.
- A tightly and honestly scoped system boundary substantially reduces the compliance workload.
- Audit logging and configuration baselines are frequent gap areas because collection is easy but review and documentation are not.
- Requirements that are not yet met belong on a POA&M rather than being left undocumented.
