1 Install SSH (Secure Shell) service to provide remote management services
SSH refers to Secure Shell. The SSH protocol family is formulated by the Network Working Group of the IETF (Internet Engineering Task Force). The content of the SSH protocol is a security protocol based on the application layer and the 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, they are vulnerable to man-in-the-middle. Attack by way of attack. It means that there is another person or a machine pretending to be a real server to receive the data sent by the user to the server, and then pretending to be the user to send the data to the real server.
SSH (Secure Shell) is a relatively reliable protocol that provides security for remote login sessions and other network services. Using the SSH protocol can effectively prevent information leakage in the remote management process. Through SSH, all transmitted data can be encrypted, and DNS spoofing and IP spoofing can also be prevented. SSH has an additional advantage that the transmitted data is compressed, so it can speed up the transmission. SSH has many functions. It can not only replace Telnet, but also provide a secure "channel" for FTP, Pop, and even PPP.
