Which term best describes the role of protecting and transmitting classified material in a secure manner on behalf of a contractor?

• A. Courier
• B. Custodian
• C. Cybersecurity
• D. CNWDI

Answer: (A)

The role described is the courier. A courier is the person authorized to physically move classified materials between locations while maintaining security, chain of custody, and adherence to approved transport procedures. This includes secure packaging, tamper-evident measures, controlled handoffs, and tracking, all focused on in-transit protection. A custodian, by contrast, is typically responsible for safeguarding materials at rest within a facility, not the transport itself. Cybersecurity addresses protecting digital information and systems rather than physical transit. CNWDI is not a standard term for transporting classified material. So the courier best fits the requirement of protecting and transmitting classified material securely on behalf of a contractor.
