CUI Documents Must Be Reviewed: A Comprehensive Guide to Compliance and Security

Controlled Unclassified Information (CUI) is a crucial aspect of government and contractor security. Understanding what constitutes CUI and why its proper handling is so vital is the first step. The requirement that CUI documents must be reviewed regularly is not merely a bureaucratic hurdle; it's a cornerstone of protecting sensitive information and maintaining national security. This article will delve into the intricacies of CUI review, exploring the "who," "what," "when," "where," "why," and "how" of this essential process.

Understanding Controlled Unclassified Information (CUI)

Before diving into the review process, it's crucial to understand what CUI actually is. CUI is information that the U.S. government creates or possesses, or that an entity creates or possesses for or on behalf of the U.S. government, that requires safeguarding or dissemination controls consistent with laws, regulations, and government-wide policies. It's information that, while not classified, still requires protection to prevent harm to national security or other government interests.

• Key Characteristics of CUI:
  • Not classified as Confidential, Secret, or Top Secret.
  • Requires safeguarding or dissemination controls.
  • Governed by laws, regulations, and government-wide policies.
  • Can be created by or for the U.S. government.

CUI is categorized into different types, each requiring specific handling procedures. These categories are defined in the CUI Registry, maintained by the National Archives and Records Administration (NARA). Some common examples of CUI include:

• Personally Identifiable Information (PII): Information that can be used to identify an individual, such as Social Security numbers, dates of birth, and addresses.
• Protected Health Information (PHI): Medical information protected under the Health Insurance Portability and Accountability Act (HIPAA).
• Financial Information: Data related to financial transactions, accounts, and investments.
• Legal Information: Information related to legal proceedings, contracts, and intellectual property.
