Controlled Unclassified Information (CUI) is a category of sensitive but unclassified information that the U.S. government deems important enough to protect. It refers to information that requires safeguarding or dissemination controls, as specified by laws, regulations, or government-wide policies, but is not classified under executive orders that define national security classification levels.
CUI can include a range of information, such as:
- Personal Identifiable Information (PII): Data that can identify individuals, like Social Security numbers or medical records.
- Financial Information: Data related to financial operations or transactions.
- Proprietary Information: Business-sensitive information, such as trade secrets or intellectual property.
- Legal and Regulatory Information: Documents related to legal proceedings or regulatory compliance.
The purpose of CUI is to standardize the handling of sensitive information across various federal agencies and contractors, ensuring consistent protection and reducing the risk of unauthorized access or disclosure.
