Which Linux command is used for secure remote login?

• A. Ifconfig
• B. Ping
• C. Ps
• D. Ssh

Answer: (D)

Secure remote login is achieved with SSH. SSH creates an encrypted connection between your machine and a remote system, so your login credentials and remote commands are protected from eavesdropping and tampering. It authenticates both ends, typically using passwords or, more securely, public/private key pairs, and it lets you run commands remotely or transfer files securely (via SCP or SFTP). By default, it uses port 22. The other commands listed have different purposes: one configures network interfaces, another checks if a host is reachable, and another shows running processes. SSH is the tool you use for secure remote access.
