How must classified information be transmitted to foreign entities?

Classified information must be transmitted to foreign entities through secure channels, in compliance with established protocols, to ensure the safeguarding of sensitive data. This requirement is critical because transmitting classified information through insecure methods can lead to unauthorized access, breaches of national security, or compromises of sensitive operations and information.

Using secure channels—such as encrypted communications or designated secure facilities—ensures that only authorized personnel have access to the transmitted information. Compliance with established protocols also ensures that proper handling procedures are followed, minimizing risks associated with miscommunication, accidental disclosure, or interception by unauthorized actors.

In contrast, methods such as open channels or informal email communications do not provide the necessary security safeguards to protect classified information. Similarly, using any available method for delivery could expose sensitive information to risks that dedicated secure transmission protocols are specifically designed to mitigate.
