Which statement regarding the derivative classification process is correct?

The derivative classification process is a critical practice within information security that ensures sensitive information is adequately protected while allowing for its authorized dissemination. The correct statement emphasizes that derivative classification involves following existing classification guidance. This means that when an individual derives new classified information from already classified sources or documents, they must adhere to established guidelines that dictate how to classify, downgrade, or declassify information. This adherence ensures consistency and accuracy in the classification process and helps prevent unauthorized disclosure of sensitive information.

Following classification guidance is essential because it provides the framework needed to assess the classification level of new material derived from existing classified documents. It also ensures that the derivative classifier is in compliance with the original classification authority's directives, thus maintaining the integrity of classified information across the information management system.

The other statements do not accurately depict the derivative classification process. For instance, it is not optional—individuals designated as derivative classifiers have specific obligations under law and policy to classify information appropriately. Derivative classification certainly applies not only to original documents but also to any new materials derived from previously classified documents. Furthermore, the process can involve classified source material since derivative classifiers often work with previously classified information as a basis for their assessments and decisions.
