NIST SP 800-66 vs NIST SP 800-171A - Assessing Security Requirements for Controlled Unclassified Information (CUI)
What is the difference between NIST SP 800-66 and NIST SP 800-171A - Assessing Security Requirements for Controlled Unclassified Information (CUI)?
NIST SP 800-66 is an information security framework applying in the United States, with 8 controls across 8 domains. NIST SP 800-171A - Assessing Security Requirements for Controlled Unclassified Information (CUI) is an information security framework applying in the United States, with 97 controls across 17 domains. Both govern the same subject, so their requirements overlap; the mapping below shows which controls carry across and which are asked for by only one of them.
NIST SP 800-668 controls
NIST SP 800-171A - Assessing Security Requirements for Controlled Unclassified Information (CUI)97 controls
