Secure Shell

Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. It provides a secure channel for remote login, command execution, file transfers, and tunneling of other protocols. SSH is widely used by system administrators, developers, and network engineers to manage servers and network devices.

Also known as: SSH, Secure Shell Protocol, OpenSSH, ssh-client, ssh-server

Why learn Secure Shell?

Developers should learn SSH for securely accessing remote servers, automating deployments, and managing cloud infrastructure. It is essential for tasks like remote debugging, server administration, and secure file transfers using SCP or SFTP. SSH is particularly crucial in DevOps, cloud computing, and any environment requiring secure remote access.
