Pursuant to Executive Order 13,556 and as forecasted in the draft of the National Institute for Standards and Technology’s (“NIST”) Special Publication (“SP”) 800-171, the National Archives and Record Administration (“NARA”) released on May 8, 2015 a proposed rule addressing the government-wide designation and safeguarding of Controlled Unclassified Information[1] (“CUI”) (“the Proposed CUI Rule” or “the Rule”). On June 18, 2015, NIST released the final version of SP 800-171, which provides guidance for protecting the confidentiality of CUI residing in nonfederal information systems.
SP 800-171 also includes interpretations of and best practices for compliance with the Proposed CUI Rule. As a result, reading SP 800-171 in conjunction with the Proposed CUI Rule suggests that contractors may soon face significant additional burdens for safeguarding government information on their systems.
