Which remote access protocol provides unsecured remote CLI access?

Console access is direct physical access to a device's console port, not a remote access protocol over a network.

Telnet provides remote command-line interface (CLI) access but is unsecured because it transmits all data, including usernames and passwords, in plain text, making it vulnerable to eavesdropping and interception.

SSH (Secure Shell) provides secure, encrypted remote CLI access, protecting data from interception.

Bash is a command-line shell program, not a remote access protocol itself, though it can be accessed remotely via protocols like SSH.
