Announcement
This update to NIST SP 800-171 represents over one year of data collection, technical analyses, customer interaction, redesign, and development of the security requirements and supporting information for the protection of Controlled Unclassified Information (CUI). Many trade-offs have been made to ensure that the technical and non-technical requirements have been stated clearly and concisely while also recognizing the specific needs of both federal and nonfederal organizations.
In response to the 1600+ comments received on the initial public draft and its supporting resources, NIST continued to refine the security requirements to:
- Reduce the number of organization-defined parameters (ODP)
- Reevaluate the tailoring categories and tailoring decisions
- Restructure and streamline the discussion sections
Additional files include an FAQ, a detailed analysis of the changes between Revision 2 and Revision 3, and a prototype CUI Overlay.
Concurrently, the initial public draft (ipd) of NIST SP 800-171Ar3 (Revision 3), Assessing Security Requirements for Controlled Unclassified Information, is also available.
Submit Your Comments
The public comment period is open now through January 12 January 26, 2024. We strongly encourage you to use this comment template if possible, and submit it to 800-171comments@list.nist.gov.

- Re-categorized controls (e.g., controls formerly categorized as NFO)
- New tailoring criterion (e.g., other related controls [ORC])
- Inclusion of organization-defined parameters (ODP)
- New or revised requirements
- Prototype CUI overlay
Comments received in response to this request will be posted on the Protecting CUI project site after the due date. Submitters’ names and affiliations (when provided) will be included, while contact information will be removed.
Please direct questions and comments to 800-171comments@list.nist.gov.
NOTE: A call for patent claims is included on page iv of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.
The protection of Controlled Unclassified Information (CUI) resident in nonfederal systems and organizations is of paramount importance to federal agencies and can directly impact the ability of the Federal Government to successfully conduct its essential missions and functions. This publication provides federal agencies with recommended security requirements for protecting the confidentiality of CUI when the information is resident in nonfederal systems and organizations. The requirements apply to components of nonfederal systems that process, store, or transmit CUI or that provide protection for such components. The security requirements are intended for use by federal agencies in contractual vehicles or other agreements established between those agencies and nonfederal organizations.
