When you access a remote server through the SSH protocol, the security risks are considerably reduced. In the case of the client and of the system itself, security is improved thanks to encryption; secure shell is responsible for encrypting all sessions. Thus, it is impossible for anyone to access the passwords, the customer's access data, or what the client has written. When a connection is made through the Secure Shell protocol, the remote user is authenticated by the system. Then, we proceed to transfer this information from the host client and return the data to the client.
