The ISOO CUI Registry, operated by the U.S. Information Security Oversight Office (ISOO), is a database that serves as a comprehensive repository of Controlled Unclassified Information (CUI) categories and subcategories, including associated markings, handling procedures, and other guidance. The purpose of the ISOO CUI Registry is to provide a standardized reference and guidance system for the management and protection of CUI across the U.S. government and its contractors. Here are some specific purposes and benefits of the ISOO CUI Registry:
- Standardization: The registry defines and standardizes categories and subcategories of CUI. This helps ensure consistency in identifying, marking, and handling CUI across different government agencies, departments, and contractors.
- Clarity: The registry provides clear definitions and descriptions for each CUI category and subcategory. This clarity helps individuals and organizations understand what type of information falls under the CUI designation and how it should be handled.
- Marking and Labeling: It offers guidance on marking and properly labeling documents and materials containing CUI. This helps prevent inadvertent disclosure and ensures that those who handle CUI are aware of its sensitivity.
- Access Control: The registry provides information on access controls and who should have access to specific CUI categories. This helps restrict access to authorized personnel with a legitimate need-to-know.
- Guidance on Handling: It includes handling procedures and best practices for different types of CUI. This guidance assists agencies and contractors in implementing the necessary security measures to protect CUI.
- Training and Education: The registry can be used as a resource for training and educating personnel about CUI handling requirements. It helps employees and contractors understand their responsibilities regarding CUI protection.
- Compliance: Agencies and contractors can use the registry to ensure that their handling and protection of CUI align with established standards and regulations. This aids in compliance with government requirements.
- Efficiency: By providing a centralized resource for CUI management, the ISOO CUI Registry streamlines the process of identifying and handling sensitive but unclassified information. This promotes efficiency and consistency in government operations.
- Audit and Oversight: The registry supports audit and oversight activities by providing a clear reference point for evaluating an organization’s compliance with CUI protection requirements.
Overall, the ISOO CUI Registry is a valuable tool for enhancing the security and protection of sensitive information that is not classified but still critical to national interests and security. It contributes to a more organized and standardized approach to managing CUI throughout the U.S. government and its various entities.
