Derivative Classification Training Practice Exam

According to the SCG, what does classification by compilation mean?

1. Classified documents compiled from different sources

2. Classified information revealed when related details are combined

3. Classified information inferred from observation

4. Classified material that is commonly known

The correct answer is: Classified information revealed when related details are combined

Classification by compilation refers to the idea that when sensitive information is gathered or combined from various sources, even if none of the individual pieces of information are classified on their own, the resulting combination can still lead to the revelation of classified information. This is particularly relevant in contexts where the aggregation of seemingly innocuous data points can create a more comprehensive understanding that may be sensitive or classified. The selection aligns with the understanding of how classified information can emerge from the synthesis of various non-classified pieces, emphasizing the need to assess the potential implications of data when compiled rather than evaluated individually. This is critical for maintaining information security, as it highlights that the context and relationships between pieces of information can elevate their sensitivity. The other options do not accurately capture this concept. For instance, classified documents compiled from different sources may not reflect the nuanced concerns that arise from compilation; rather, it describes a tangible act of assembling documents. Inferred information from observation and commonly known material do not pertain to the specific process of classification by compilation, as they address different aspects of information security and classification.
