Controlled Unclassified Information (CUI) refers to sensitive data that, while not classified, requires specific handling, safeguarding, or dissemination controls. CUI typically applies to information that is generated or possessed by the U.S. government, contractors, or other entities involved in government-related activities, and is subject to regulations designed to protect national security, privacy, and other interests.
Key Aspects of CUI:
- Sensitive but Unclassified: CUI is information that is too sensitive to be publicly disclosed but does not meet the criteria for classification as Top Secret, Secret, or Confidential. It includes data such as financial information, intellectual property, personally identifiable information (PII), and law enforcement data.
- Regulatory Framework: The handling of CUI is governed by specific regulations and standards, such as the National Archives and Records Administration (NARA) guidelines and the Federal Acquisition Regulation (FAR). These rules ensure that CUI is protected appropriately based on its sensitivity level.
- Protection and Handling: CUI must be protected using specific security measures, including encryption, access control, and secure transmission. The goal is to prevent unauthorized access or disclosure, ensuring that sensitive information remains safe without hindering government operations.
- Compliance: Entities handling CUI, including government agencies and contractors, are required to implement practices and systems that comply with CUI standards, ensuring the protection of this information through policies like NIST SP 800-171.
Managing CUI properly is crucial for maintaining national security and privacy, as mishandling or unauthorized disclosure could have serious implications for both individuals and organizations.
