Final answer:
To access Controlled Unclassified Information (CUI), an individual must have a lawful government purpose and usually undergo a background check. This process ensures that sensitive information remains protected and is disclosed only to those with a legitimate need to know.
Step-by-step explanation:
To obtain access to Controlled Unclassified Information (CUI), an individual must first have a lawful government purpose to access the information and, typically, must also undergo a background investigation or screening process appropriate for the level of sensitivity. The exact requirements can vary depending on the agency and the type of CUI.
CUI refers to information that, while not classified, is still sensitive and requires safeguarding or dissemination controls pursuant to and consistent with applicable law, regulations, and government-wide policies. To handle CUI, individuals often need to demonstrate a need to know, complete relevant training, and comply with outlined handling procedures.
For instance, someone working with CUI in the Department of Defense (DoD) might need to follow the Defense Federal Acquisition Regulation Supplement (DFARS) requirements and obtain a Cybersecurity Maturity Model Certification (CMMC). On the civilian side, agencies might require adherence to the National Institute of Standards and Technology (NIST) Special Publication 800-171. Overall, the protective measures and processes aim to mitigate the risk of unauthorized disclosure of sensitive information.
