Which term describes the process of safeguarding classified information by an individual or organization responsible for such information?

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

Answer: (A)

Custodian refers to the person or organization entrusted with protecting classified information. This role includes implementing proper storage, handling, access controls, and accountability to ensure the material remains secure and in compliance with security rules. The function is about ongoing stewardship, not just movement or system protection. A courier is focused on moving materials, not safeguarding them on an ongoing basis. Cybersecurity covers protecting information systems and networks, which is broader than the custodial protection of the information itself. CPI isn’t about guarding classified information. So, the term for the party responsible for safeguarding is custodian.
