What information can typically be found in the classification authority block of a classified document?

The classification authority block of a classified document is specifically designed to provide key information regarding the classification of that document. This block typically includes details such as the date on which the document is set to be declassified, the identity of the individual or entity who created the classification (often the original classification authority), and the source of the information that necessitated the classification.

Including the date for declassification is crucial because it informs users about when the material may be reviewed for potential declassification, thereby ensuring that classified information does not remain unnecessarily protected beyond its useful life. Mentioning the creator’s details reinforces accountability and traceability, which are vital in maintaining the integrity of classification protocols. Additionally, noting the source of the information offers context about why the classification was necessary, as it can indicate whether the information was derived from other classified materials or classified sources.

In contrast, options that mention encryption level, storage location, review deadlines, and access restrictions do not belong specifically to the classification authority block but might be found in other documents or sections related to information security.
