Why is it crucial to protect Controlled Unclassified Information (CUI)?

Protecting Controlled Unclassified Information (CUI) is crucial because, although it is not classified, it can still contain sensitive data that, if disclosed inappropriately, can harm national security, privacy, or other interests. CUI encompasses information that, while not classified, is still subject to specific handling and safeguarding requirements due to potential risks associated with its unauthorized disclosure. This can include information related to national defense, law enforcement, or personally identifiable information (PII), among other categories.

The distinction between CUI and classified information lies primarily in the formal designation and the specific protocols governing handling and sharing. However, the sensitivity of the information itself underscores the importance of protecting it, which is why proper measures and protocols are mandated across organizations handling CUI. Ensuring CUI is safeguarded helps maintain the integrity and confidentiality of information necessary for national interests and the protection of individuals' rights.
