When derivative classifiers incorporate classified information from existing content into a new document without requiring additional interpretation, the classification of that information is considered to be derived from the original source. This means that the new document inherits the classification level of the source material, maintaining the same security controls. The classifier must ensure that all applicable classification markings and guidance from the original document are accurately reflected in the new document. Proper handling is critical to prevent unauthorized disclosure of classified information.
