What does it mean to "mark" classified documents correctly?

Marking classified documents correctly means that the classification level and handling instructions must be clearly indicated on the document. This process ensures that individuals who access or handle the document are fully aware of its sensitivity level and the precautions that must be observed to protect it. Proper marking prevents unauthorized access and helps maintain the integrity and confidentiality of classified information.

In addition to specifying the classification level, which could range from confidential to top secret, this marking typically includes a brief description of how the document should be handled, such as whether it needs to be stored in a locked container or if it is required to be marked as “for official use only.” This comprehensive approach to marking is vital in a secure environment, as it conveys necessary information to personnel and reinforces security protocols.
