Sensitive information that could affect the safety and security of U.S. citizens is often classified by the federal government. However, not all important data meets the criteria for formal classification. This type of information is known as Controlled Unclassified Information (CUI), and it falls into two categories: CUI Basic and CUI Specified.
CUI Basic refers to unclassified data that still requires safeguarding and handling practices, even though it is not protected by specific laws or regulations.
