What does the term "original classification" refer to?

The term "original classification" specifically refers to the initial determination that information requires protection due to its potential impact on national security. This is a critical step in the classification process, as it establishes which pieces of information need to be marked as classified and at what level, helping to ensure that sensitive information is adequately safeguarded from unauthorized disclosure.

This concept is fundamental in the realm of classified information, as it sets the stage for subsequent handling, management, and protection of that information throughout its lifecycle. Understanding original classification is essential for anyone working with classified materials, as it underscores the importance of making appropriate and informed decisions regarding what needs to be classified right from the beginning.
