Explanation

SSH (Secure Shell) is the standard protocol for establishing encrypted, authenticated remote command-line sessions with Linux and Unix-based systems. It operates on port 22 and protects credentials and data in transit. SFTP (SSH File Transfer Protocol) is used for secure file transfers, not interactive management sessions. RDP (Remote Desktop Protocol) is a Windows-specific graphical remote access protocol. Telnet provides remote access but transmits all data, including passwords, in plaintext, making it insecure and inappropriate for production use.
