Which protocol provides encryption for network services like remote login or remote file transfer?

• A. FTP
• B. SSH
• C. Telnet
• D. HTTP

Answer: (B)

SSH provides encryption for network services like remote login and remote file transfer. It secures the entire session, protecting login credentials and data from eavesdropping and tampering, and supports secure file transfer methods such as SFTP and SCP. FTP and Telnet transmit credentials and traffic in plaintext, making them insecure for remote access or file transfers. HTTP is web traffic and, on its own, not encrypted (though HTTPS adds encryption); the protocol that specifically secures remote login and file transfer is SSH.
