What is the process of bringing COMSEC material into accountability called?

The process of bringing COMSEC material into accountability is known as "Receiving." This term specifically refers to the procedures undertaken when COMSEC items are delivered to an organization, ensuring that these sensitive materials are properly counted, verified, and recorded to maintain a secure inventory.

When COMSEC materials are received, it is crucial to document their condition and quantity accurately to verify that the items match the shipping manifests and to confirm that they are intact. This receipt process is foundational to effective COMSEC operations, as it establishes a compliant chain of custody and secures critical communication materials from the point of entry. Properly handling the receiving process helps to uphold national security measures by preventing unauthorized access or misplacement of sensitive information.

While the other options mention aspects related to the handling or recording of COMSEC material, they do not specifically pinpoint the formal process associated with the receipt and initial accountability of COMSEC items like "Receiving" does.
