A technician needs to ensure all data communications on all network devices are encrypted when logging in to the console. Which of the following protocols should the technician enable?

Secure Shell (SSH) is a cryptographic network protocol that provides secure, encrypted remote access and command-line interface capabilities for network devices and servers. By enabling SSH, all data, including login credentials and commands, transmitted during a console session is encrypted, protecting against eavesdropping and unauthorized access.

LDAP (Lightweight Directory Access Protocol) is used for accessing and maintaining distributed directory information services, not for encrypted remote console logins.

FTPS (File Transfer Protocol Secure) is a protocol used for secure file transfers, not for remote command-line console access.

SMTP (Simple Mail Transfer Protocol) is an internet standard for sending and receiving email, not for secure console logins to network devices.
