Final answer:
Hand-carrying is authorized when the classified information is not available at the destination. It ensures the security of the information and reduces the risk of security breaches.
Step-by-step explanation:
In the context of handling classified information, hand-carrying refers to physically transporting the information by hand rather than using other means such as electronic transfer or mail. Hand-carrying is authorized when the classified information is not available at the destination, meaning that the information is not accessible through other secure means.
For example, if a government official is traveling to another country and needs access to classified information during their trip, they may be authorized to hand-carry the information to ensure its security.
This practice ensures that the information remains in the possession and control of authorized individuals throughout the transportation process and minimizes the risk of potential security breaches.
