What Does Controlled Unclassified Information (CUI) Mean?
Controlled unclassified information (CUI) in a new category of unclassified information that replaced the various categories used for sensitive but unclassified information. CUI was created by former President George W. Bush in a memo dated May 2008. A further order by President Barack Obama allowed for new handling of CUI to be established by the National Archives and Records Administration (NARA). CUI is unclassified information relating to the interests of the U.S. federal government or outside entities it believes should be protected.
