Which of the Following is Not an Example of CUI

In today’s information-rich landscape, the proper handling and classification of sensitive data are of utmost importance to safeguard national security and maintain organizational integrity. One critical classification that plays a pivotal role in this context is Controlled Unclassified Information (CUI). However, it’s crucial to distinguish what does and doesn’t fall under the purview of CUI. In this article, we’ll explore the nuances of CUI and shed light on why information classified under specific executive orders and acts isn’t considered as such.

Decoding Controlled Unclassified Information (CUI)

Controlled Unclassified Information (CUI) refers to information that requires safeguarding or dissemination controls, but doesn’t meet the criteria for classification as “classified,” “secret,” or “top-secret.” It’s a category designed to standardize the way sensitive but unclassified information is handled across various government agencies and organizations. CUI encompasses a wide range of data, including technical, financial, legal, and operational information that is critical to national security, privacy, and safety.

Defining the Boundaries of CUI

While CUI covers a vast spectrum of sensitive information, there are instances where certain information is excluded from its classification. A key distinction lies in information classified under Executive Order No. 13526 and the Atomic Energy Act. Any data that bears labels such as “classified,” “secret,” or “top-secret” based on these classifications is not designated as CUI. This exclusion is rooted in the fact that these classifications come with their own distinct set of handling protocols, procedures, and security requirements.

Executive Order No. 13526 and the Atomic Energy Act

Executive Order No. 13526, signed by President Barack Obama in 2009, outlines the framework for classifying, safeguarding, and declassifying national security information. This order sets the stage for various levels of classified information, ranging from “confidential” to “top-secret.” These designations are carefully assigned based on the sensitivity of the information and its potential impact on national security.

The Atomic Energy Act, on the other hand, governs the classification and declassification of information related to nuclear materials and facilities. The act empowers the government to regulate the dissemination of information that could potentially compromise the safety of nuclear operations and facilities.

Why Classified Information Isn’t CUI

The rationale behind not designating information classified under Executive Order No. 13526 and the Atomic Energy Act as CUI is twofold. Firstly, the classifications under these orders entail specific security protocols and procedures that address the unique risks associated with classified data. Secondly, the stringent requirements for handling classified information are tailored to ensure the highest level of protection, often involving restricted access and controlled dissemination.


In conclusion, Controlled Unclassified Information (CUI) plays a vital role in managing and safeguarding sensitive unclassified data across diverse sectors. However, it’s essential to understand that information classified under Executive Order No. 13526 and the Atomic Energy Act falls outside the realm of CUI. The distinct security requirements associated with “classified,” “secret,” or “top-secret” information underscore the importance of handling and protecting such data according to their specific classifications.

As organizations and government agencies continue to navigate the complexities of information security, a comprehensive understanding of CUI and its boundaries is indispensable. This knowledge empowers decision-makers to make informed choices about information handling, classification, and dissemination, ensuring that national security and organizational integrity remain at the forefront.
