Short Answer 
Derivative classification involves assessing new documents to determine their security classification based on existing classified information, ensuring sensitive details are not improperly disclosed. This process requires identifying classified information, understanding original classification guidance, and following rules for safeguarding data to prevent unauthorized disclosures.
Step 1: Understanding Derivative Classification
The process of derivative classification involves evaluating new documents to determine their security classification based on existing classified information. This is essential to ensure that specific details are not improperly disclosed. The derivative classifiers must be familiar with the original classification guidance and apply these rules to safeguard sensitive information correctly.
Step 2: Identification of Classified Information
When a new document is created, it may disclose information from classified sources, such as the individuals Barkley and James. Identifying which pieces of information are classified is critical. This involves determining whether the release of this information underlies any existing security classifications. The derivative classifiers must carefully analyze the context to avoid unauthorized disclosures.
Step 3: Following Rules for Safeguarding Data
Derivative classifiers must adhere to established rules to protect classified materials effectively. This requires understanding and training on guidelines about what information can be revealed and under what circumstances. To ensure compliance and safety, classifiers should be well-versed in the following:
- Original classification guidance
- Identification techniques for sensitive information
- Proper marking and handling of classified documents
