Which of the following groups is NOT responsible for derivative classifiers?

The assertion that derivative classifiers must have original classification authority is indeed accurate. Original classification authority is a designation given to individuals who are authorized to make classification decisions on information based on its sensitivity and need for protection. Derivative classifiers, on the other hand, are responsible for classifying information derived from already classified sources and materials but do not hold original classification authority themselves.

By definition, derivative classifiers utilize existing classified information and apply that classification to new documents or materials based on their content. They can do so based on established guidelines or instructions set forth by the original classifier. This means that derivative classification is a process that builds on the existing classification framework created by those with original classification authority.

When considering the other groups mentioned, they all have defined roles related to the derivative classification process. Classification authority from federal agencies pertains to the overarching framework under which derivative classifiers operate. Security managers oversee compliance with classification protocols, ensuring that all individuals involved in the classification process follow proper procedures. Supervisors in related fields typically provide guidance and oversight to derivative classifiers, ensuring that their work aligns with classification policies.

Thus, the understanding that derivative classifiers must operate without original classification authority is what makes recognizing option A as the correct choice essential in grasping the roles and responsibilities in the classification hierarchy
