What is the CUI Registry?

The CUI (Controlled Unclassified Information) Registry is a comprehensive government resource maintained by the Information Security Oversight Office (ISOO) under the National Archives and Records Administration. The registry serves as the authoritative source for all categories and subcategories of controlled unclassified information used throughout the federal government. It provides standardized definitions, marking requirements, and handling procedures for information that requires protection but does not meet the threshold for classification.

Understanding ISOO and Its Role

The Information Security Oversight Office is an agency component of the National Archives and Records Administration responsible for implementing and monitoring compliance with executive orders on classified and controlled information. ISOO oversees government-wide policies related to information security and maintains the CUI Registry as a critical tool for agencies. ISOO works to ensure that sensitive information is protected consistently across all federal departments and agencies.

Purpose of the CUI Registry

The primary purpose of the CUI Registry is to establish a unified system for protecting federal information that requires safeguarding but is not classified. Before the CUI program, agencies used dozens of different marking systems and terminology for sensitive unclassified information, creating confusion and inconsistency. The registry standardizes marking requirements, handling procedures, and storage protocols across all federal agencies, ensuring that sensitive information receives appropriate protection regardless of which agency manages it.

Categories of CUI

The CUI Registry organizes controlled unclassified information into specific categories and subcategories, such as: Export Controlled Information, Privacy Information, Critical Infrastructure Information, Proprietary Information, Law Enforcement Information, and others. Each category has defined marking requirements and handling procedures. Agencies must consult the registry to determine the appropriate classification and handling for information in their custody.

Compliance and Implementation

Federal agencies are required to comply with CUI requirements outlined in the registry. This includes properly marking documents, controlling distribution, implementing appropriate security measures, and training personnel. The CUI program helps prevent accidental disclosure of sensitive information while streamlining the management of unclassified information that still requires protection. Non-compliance can result in security breaches and administrative consequences for agencies.
