Which step is not part of derivative classification?

• A. Determining protection against unauthorized disclosure
• B. Classifying information based on public records
• C. Utilizing security classification guides
• D. Marking material based on previous classifications

Answer: (B)

The correct response identifies that classifying information based on public records is not part of derivative classification. Derivative classification involves taking already classified information and determining its classification level or how it should be marked based on existing classification guidelines, security policies, and protecting against unauthorized disclosure.

Classifying information that is publicly available does not fall under the derivative classification process because such information is not classified to begin with. Derivative classification is concerned with the treatment of classified material and the assignment of classification markings, whereas public records do not require this consideration since they do not contain sensitive information that needs protection.

In contrast, steps like determining protection against unauthorized disclosure, utilizing security classification guides, and marking material based on previous classifications are all integral to the derivative classification process. These steps ensure that classified information remains secure and is properly handled according to legal and procedural frameworks.
