SSH Client
An SSH client is a software application that enables secure remote access and management of servers, network devices, and other systems over an encrypted SSH (Secure Shell) protocol connection. It allows users to execute commands, transfer files, and tunnel network traffic securely across untrusted networks like the internet. Common functionalities include terminal emulation, key-based authentication, and port forwarding.
Developers should learn and use SSH clients for securely administering remote Linux/Unix servers, cloud instances, and IoT devices, especially in DevOps, system administration, and backend development roles. It is essential for tasks like deploying applications, troubleshooting production issues, and automating scripts via SSH, providing a critical security layer against eavesdropping and tampering compared to insecure protocols like Telnet.
