SSH (Secure Shell) is a network protocol that provides a secure and encrypted method for accessing and managing remote computers or servers. In simple terms, SSH allows you to securely connect to another computer over an insecure network, such as the internet, and execute commands or transfer files.
To understand SSH, imagine a secure tunnel between your computer and a remote computer. SSH ensures that any communication between the two is encrypted and protected from unauthorized access or interception.
When you use SSH, you establish a connection between your local computer (the client) and a remote computer (the server). This connection allows you to execute commands, transfer files, or perform other operations on the remote system as if you were physically present.
SSH encrypts the data being transmitted between the client and the server, including login credentials, commands, and transferred files. This encryption ensures that sensitive information remains secure and private during transmission.
SSH authentication typically involves the use of cryptographic keys, such as a public key and a private key. These keys verify the identity of the client and server, preventing unauthorized access.
SSH is widely used by system administrators, developers, and IT professionals to remotely manage servers, configure network devices, securely transfer files, and perform other administrative tasks.
SSH can be accessed through command-line interfaces or graphical user interfaces (GUI) using software clients like OpenSSH, PuTTY, or WinSCP. It is supported on various operating systems, including Linux, macOS, and Windows.
