What protocol does SonicWall use for secure email delivery?

• A. HTTP (Hypertext Transfer Protocol)
• B. FTP (File Transfer Protocol)
• C. TLS (Transport Layer Security)
• D. SSH (Secure Shell)

Answer: (C)

SonicWall utilizes TLS (Transport Layer Security) for secure email delivery, which is vital for ensuring confidentiality and integrity during the transmission of emails. TLS encrypts the connection between mail servers, making it significantly more difficult for unauthorized users to intercept or tamper with the information being sent. This protocol effectively protects sensitive data contained within emails from potential breaches. In contrast, HTTP is primarily used for transferring web pages, and FTP is focused on transferring files, neither of which encompasses secure email transmission. SSH is designed to provide a secure channel over an unsecured network for shell access and is not applicable to email delivery. By using TLS, SonicWall ensures that emails are transmitted securely, aligning with best practices for cybersecurity and data protection.
