SSHops is a term that refers to the secure shell (SSH) protocol used for establishing secure connections between devices on an unsecured network. It is commonly employed for remote command-line logins and other secure network services over an insecure network. The primary function of SSH is to provide a secure channel over which client-server applications can communicate. This is achieved through encryption, which protects the data transmitted between the client and the server from eavesdropping and tampering.

SSH operates using a client-server architecture. An SSH client is installed on the user's local machine, and an SSH server is installed on the remote machine the user wishes to connect to. When a connection is initiated, the client and server negotiate security parameters, including encryption algorithms and authentication methods. Authentication can be done using passwords, public-key cryptography, or other methods. Once authenticated, an encrypted tunnel is established, allowing for secure data transfer.

The SSH protocol is widely used in various scenarios, including remote administration of servers, secure file transfer (using SCP or SFTP, which are built on top of SSH), and tunneling other network protocols to enhance their security. Its reliability and robust security features have made it a cornerstone of modern network security practices, particularly in Linux and Unix-like operating systems. Despite its widespread use, understanding the underlying principles of SSH is crucial for maintaining secure network environments.
