Mandatory Controlled Unclassified Information, also known as CUI, is a term that refers to sensitive but unclassified information that needs protection based on federal laws and regulations. CUI classification was initiated to standardize the way non-classified information is safeguarded and managed across the government, contractors, and grant recipients who aren’t authorized to access confidential information.
CUI classification covers a wide range of information, including legal, scientific, technical, or other types of information that are crucial to the operations of federal agencies. This information needs to be protected to prevent any unauthorized release, misuse, or exploitation that could cause damage to national security, economic interests or breach of privacy.
CUI classification is a well-defined system designed to make it easier for non-governmental actors to identify, protect and disseminate sensitive but unclassified information. It involves marking documents and other data with CUI labels. The use of CUI markings communicates to everyone handling the information that it has sensitive but unclassified content and, therefore, needs protection.
CUI markings include a label with a specific category that describes the information in the document. For example, if the information is related to financial systems or services, it may be marked as “Finance.” Additionally, there are markings that may indicate handling instructions such as who may have access to the document, how the information should be handled, and where the information should be stored.
CUI classification is essential in ensuring that sensitive but unclassified information is adequately protected. Proper CUI markings make it clear how the information should be handled from its creation until its disposal. It offers a standardized approach to managing sensitive, but unclassified information, making it easier for non-governmental actors to implement security controls appropriate to the degree of risk.
To ensure CUI is correctly managed, all personnel handling it must be trained on its handling, marking, storage and destruction requirements, and be aware of the risks associated with improperly marking, storing, transmitting, or disposing of CUI.
In conclusion, CUI markings and classification are essential components of an effective information security strategy. Proper CUI markings make it easier to manage sensitive but unclassified information, safeguarding it from unauthorized access, loss, or theft. Adhering to CUI classification guidelines ensures that federal agencies, contractors, and grant recipients meet national security and information protection requirements, safeguarding sensitive but unclassified information from unauthorized access or disclosure.
