Which protocols does SonicWall utilize for secure remote management of its firewall?

SonicWall utilizes HTTPS and SSH for secure remote management of its firewalls, making this the correct choice.

HTTPS (Hypertext Transfer Protocol Secure) is essential because it encrypts the data exchanged between a user's browser and the SonicWall device, ensuring that sensitive configuration and management data are protected from eavesdropping or interception. This adds an essential layer of security, which is critical when managing network infrastructure remotely.

SSH (Secure Shell) is another secure protocol that provides a secure channel over an unsecured network. SSH is primarily used for command-line access to devices, allowing administrators to securely log in, execute commands, and manage configurations without exposing the data to potential attacks.

In contrast, other protocols listed have significant security concerns. FTP and HTTP do not provide encryption, leaving data vulnerable during transmission. Telnet, like HTTP, transmits data in plaintext, making it insecure for remote management. SMTP and POP3 are related to email transmission and management rather than secure communication for firewall management.

Thus, HTTPS and SSH are the appropriate and secure options for managing SonicWall firewalls remotely.
