SSH is a network protocol designed for secure remote access and secure communication over an insecure network. The statement that SSH stands for Secure Shell is accurate, and that name reflects its purpose: providing a secure channel to run commands remotely and perform other secure services like file transfer. SSH encrypts traffic, authenticates users, and protects data from eavesdropping and tampering, which is why it’s widely used for administering servers and securely transferring files (via SFTP or SCP). It isn’t a hardware protocol, it isn’t the same as FTP, and it isn’t deprecated—SSH remains current, regularly updated, and actively used in everyday networking.
