What is meant by the term "compilation" in the context of classified information?

The term "compilation" in the context of classified information refers to the collection of disparate non-classified items that, when combined, may create a piece of information that is sensitive enough to warrant classification. This concept is important because it acknowledges that individual non-classified items might not pose a risk on their own, but together they can reveal classified information or sensitive national security details.

Understanding this process is crucial for information security as it highlights the need for vigilance in handling and sharing information, since the aggregation of seemingly harmless data can lead to vulnerabilities. Effective security protocols must account for compilations to prevent the unintended exposure of classified information through seemingly benign means.
