SSH stands for Secure Shell, which is a cryptographic network protocol used for secure data communication between a client and a server. It provides a secure channel over an unsecured network by using encryption, ensuring that the data transmitted is protected from eavesdropping or interception by unauthorized parties. SSH is commonly used for remote access to servers, allowing users to execute commands and manage systems securely over an insecure network, such as the internet.

The protocol also supports various authentication methods, including password-based and key-based access, enhancing security. SSH can also be used to securely transfer files through associated tools like SCP (Secure Copy Protocol) and SFTP (SSH File Transfer Protocol). Its significance in maintaining confidentiality and integrity in data transmission makes it a foundational protocol in network security practices.
