What information must be marked at the top or bottom of a dynamic document?

The requirement to mark a dynamic document with working statements indicating classification use is essential for ensuring that individuals accessing the document understand its sensitivity and the appropriate handling procedures. This marking serves as a clear reminder of the classification level and any restrictions or caveats related to the information contained within the document. Such markings are critical in environments where information may be frequently updated or dynamically altered, as they help maintain awareness of potential risks associated with disclosure or unauthorized access.

By providing guidance on how the document may be used and who can access it, these markings underscore the importance of safeguarding classified information. Therefore, this practice aligns with the broader principles of information security, which emphasize the need to make classification status and handling requirements transparent and accessible to authorized personnel.
