End-to-end encryption provides protection against which risk during transmission?

• A. Eavesdropping by unauthorized parties during transmission
• B. Hardware failure
• C. Physical theft of the device
• D. Insider threats

Answer: (A)

End-to-end encryption protects data by encrypting it from the sender's device and only decrypting it on the recipient's device, so the content remains unreadable as it traverses the network. This means unauthorized parties who intercept the transmission—sniffers or attackers on the path—cannot access the message’s contents. Hardware failure, physical device theft, or insider access concern the device or internal systems rather than the confidentiality of data in transit. So, the risk addressed during transmission is eavesdropping by unauthorized parties.
