SSH stands for Secure Shell, which allows users to securely access remote computers over an insecure network connection. This means that you can log in to a computer without having to worry about someone else being able to see your password. In this tutorial you will learn about how to install SSH on Linux Mint.
The first thing you have to do after installing an operating system is to activate SSH on your system, because it provides an encrypted network protocol to safeguard client logins and remote server. In this way you can access the device remotely and ensure the security of the operation.
What Is SSH?

For a secure connection, both client and remote server connection should have SSH installed and enabled.
