Question: 1 / 545

What protocol did Benson implement to secure email messages?

HTTPS

IPsec

S/MIME

Implementing S/MIME (Secure/Multipurpose Internet Mail Extensions) secures email messages by providing end-to-end encryption and digital signatures. This ensures that the content of the messages is protected from unauthorized access during transmission and verifies the identity of the sender. S/MIME uses public key cryptography to encrypt the email message and securely exchange the encryption keys, thus maintaining confidentiality and integrity of the communication.

Other protocols, such as HTTPS and SSL, are more related to securing web traffic rather than specifically securing email. IPsec is a protocol suite designed to secure IP communications but does not directly relate to securing email messages. In contrast, S/MIME is tailored for email and directly addresses the concerns of email security.
