What determines the usability of COMSEC material?

The usability of COMSEC (Communications Security) material is primarily determined by the status assigned by the controlling authority. This status outlines whether the material is active, inactive, or has been superseded or declassified. Such classifications provide essential guidance on how the material can be utilized, ensuring compliance with security standards and regulations. The controlling authority's determination takes into account the material's integrity, relevance, and need for protection against unauthorized access, which ultimately ensures that only authorized personnel use COMSEC resources effectively.

Other factors, while important in their own right, do not dictate usability in the same way. The physical condition of the material is important for its functionality but does not override the status assigned by the controlling authority. The length of time since the material was created may indicate its relevance, but it is the status that dictates its usability. Lastly, the location of storage can affect access but does not inherently influence whether the material is approved for use. Therefore, the assigned status is paramount in determining usability.
