What is the classification concept called when new material aggregates information that, while not classified individually, becomes classified together?

• A. Classification by Attribution
• B. Classification by Compilation
• C. Classification by Extrapolation
• D. Classification by Context

Answer: (B)

The classification concept being referred to is known as Classification by Compilation. This concept applies when separate pieces of information, which may not be classified on their own, are combined in a way that the overall aggregation meets the criteria for classification. This means that while individual components could potentially be shared openly, their synthesis into a new compilation reveals sensitive information that warrants protective classification.

In the context of national security and intelligence, understanding this concept is crucial because it emphasizes the importance of safeguarding collective insights or connections that arise when information is synthesized, rather than merely focusing on the classification of pieces in isolation. This approach helps in maintaining the integrity and security of classified information in an interconnected scenario.

The other concepts mentioned, such as classification by attribution or extrapolation, focus on different methods of determining classification, such as the source of the information or predicting implications based on current knowledge. Classification by context refers more to the situational relevance of information rather than the act of combining multiple data points into a classified entity.
