SSH (Secure Shell)

SSH, or Secure Shell, is a protocol suite used for securely accessing network services over an unsecured network. Primarily, SSH is used for remote management of systems and applications, allowing users to log into another computer over a network, execute commands, and move files from one computer to another.

The key features of SSH include:

SSH is widely used by system administrators for managing servers and networks, and by users who need to securely transfer files using SCP (Secure Copy Protocol) or SFTP (SSH File Transfer Protocol). It is a standard tool included in many operating systems, including all Unix-like systems such as Linux and macOS, and available for Windows.

Overall, SSH is an essential tool for maintaining the confidentiality, integrity, and availability of data and systems in networked environments, making it a cornerstone of secure network administration.
