What does derivative classification involve?

Derivative classification involves the process of classifying information that is based on existing classified material. This can include the use of information that has already been classified in its original form, such as documents, reports, or data, to create new documents. When someone engages in derivative classification, they must apply the appropriate classification markings as established by the original source, as well as follow the guidelines for protection of that classified information.

This practice is crucial because it ensures that any new information derived from classified sources retains the same level of protection as the original information, maintaining national security and adherence to established protocols. Additionally, it highlights the importance of understanding the foundational sources of classified information in order to ensure that all pertinent details are accurately safeguarded and marked according to classification standards.

In contrast, other choices address different functions, such as creating entirely new classified information without a basis in existing classified material, reviewing for declassification, or misapplying classifications to public information, which do not align with the principles of derivative classification.
