How should confidential information be transmitted securely?

• A. Posting on unsecured cloud.
• B. Public email.
• C. Unencrypted USB drive.
• D. Encrypted channels, secure portals, or physical handoffs with authorization, following policy.

Answer: (D)

Confidential information must be transmitted using methods that protect confidentiality and ensure proper authorization. The best approach is to use encrypted channels, secure portals, or physical handoffs that are explicitly authorized and documented according to policy. Encryption protects the data in transit so that even if it’s intercepted, it remains unread. Secure portals add authentication, access controls, and audit trails, giving you a controlled environment for transfer. Physical handoffs, when electronic transfer isn’t feasible, rely on established authorization and a documented chain of custody to prevent unauthorized access. Following policy ensures consistent protections and accountability. Posting on unsecured cloud exposes data to unauthorized access and potential leaks. Public email can be intercepted or stored insecurely, compromising confidentiality. An unencrypted USB drive can be lost or stolen, revealing the data without any protection.
