On November 9, 2023, the National Institute of Standards and Technology (“NIST”) released the Final Public Draft (“FPD”) of Special Publication (“SP”) 800-171 Revision (“Rev.”) 3, “Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations” and the Initial Public Draft of NIST SP 800-171A Rev 3, “Assessing Security Requirements for Controlled Unclassified Information.”  The FPD of SP 800-171 Rev. 3 condenses several control requirements from the initial public draft while adding new requirements under existing controls.  The initial draft of SP 800-171A now aligns with SP 800-171 Rev. 3 and includes more detailed assessment procedures than its predecessor.  Changes in both documents forecast the evolving compliance requirements for organizations required to safeguard Controlled Unclassified Information (“CUI”).
