Secure Hosting is necessary because of the increase of attacks while SSH Client transferring files and other sensitive information. To execute commands on the server from the terminal, we can use Telnet but it is declined because of insecure. It sends the commands to the server side for execution as it is (Plain text). That is without performing any encryption techniques.
In Simple words, Secure Shell is a program which is used to log in to remote computer and can execute some commands on that machine and can also transfer some files over a network. Typically, SSH is the predecessor of Telnet Shell which is one of the important features provided by the web hosting providers for secure hosting along with SSL. With the feature SSH, we can exchange sensitive data using Secure Virtual Channel. So the anonymous person cannot intercept with our data. SSH is designed particularly to send information like passwords, public keys, and some other sensitive datum over an insecure network such as Internet with confidentiality and authentication.
Unlike Telnet, SSH sends the commands and data to be executed in the remote server only after doing some encryption and applying algorithms. With SSH, we can authenticate the remote computer and vice versa. We can also login and administer our account using UNIX/LINUX command line instructions with this secure channel in SSH Hosting. Some of the tasks that we can able to perform with the feature SSH Hosting are file transformation, running programs in the remote computer and so on.
