![]() ![]() Under SSH, data is broken down into a series of packets. Intrusion Prevention System: Key Differences and Similarities How Does SSH Work? Files can be transferred using SFTP (Secure File Transfer Protocol), an encrypted version of FTP. SSH can be used to transfer data, commands, text, and files. With SSH, you can talk to remote and your own operating systems. Such shells allow the execution of commands on machines you are connected to. When the client connects to the server, the data communication proceeds through the shells, for example, Linux terminal shell or a Windows command prompt shell. SSH obeys a client-server model where one system is labeled as the SSH client while the other machine is called the SSH server or host. SSH means you can still see that the data is being exchanged between machines, but it is hard to determine what the data is. Thus, SSH emerged as a secure way of communication where encrypted data is transferred through a tunnel to keep the data in transit safe from bad actors. It hides the data and makes it unreadable to attackers. As a result, the data exchange was susceptible to man-in-the-middle attacks, implying anyone with a packet sniffer could listen to the conversation between you and the remote machine.Ī solution to such a problem is achieved through encryption. Telnet typically transfers data without encryption. ![]() It replaced the Telnet (Teletype Network) network protocol used by machines to interact with each other. It allows authorized users to control remote machines via the internet without having physical access. It is a part of the application layer of the OSI model. Secure Shell (SSH) is a networking protocol that enables systems to communicate over an unsecured network. ![]()
