Two major NIST publications are about to be finalized on June 14: NIST Special Publication (SP) 800-171A, “Assessing Security Requirements for Controlled Unclassified Information”; and an update to the NIST SP 800-171, “Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations.” The draft 171A text may be found on the NIST site: https://csrc.nist.gov/pu blications/detail/sp/800-171a/ draft. The 800-171A is intended to help organizations develop assessment plans and conduct assessments of the security requirements in NIST SP 800-171, which defines the requirements for protecting CUI on non-Federal systems consistent with the CUI Federal regulation (32 CFR 2002.14h2).
