What is SSH?

SSH is short for Secure Shell, developed by the Network Working Group of IETF. SSH is a security protocol built on the application layer and transport layer.

Traditional network service programs, such as FTP, POP, and Telnet, are inherently insecure because they transmit data, user accounts, and user passwords in plain text on the network, attackers are vulnerable to man-in-the-middle attacks. There is another person or a machine impersonating a Real Server to receive data from the user to the server, and then impersonating the user to pass the data to the Real Server.

SSH is a reliable protocol designed for remote logon sessions and other network services. The SSH protocol can effectively prevent information leakage during Remote Management. SSH can be used to encrypt all transmitted data and prevent DNS Spoofing and IP spoofing.

Another advantage of SSH is that the data transmitted is compressed, which can speed up transmission. SSH has many functions. It can replace Telnet, provide a secure "channel" for FTP, POP, and even PPP"
