between two networked devices. SSH was designed as a replacement for Telnet and other insecure remote shells,
which send information, notably passwords, in plaintext, leaving them open for interception. The encryption used
by SSH provides confidentiality and integrity of data over an insecure network, such as the Internet. SSH uses
public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the
user, if necessary. SSH is typically used to log into a remote machine and execute commands, but it also supports
tunneling and it can transfer files using the associated SFTP or SCP protocols. See SSH Defined.
What is SFTP? File Transfer Protocol (FTP) is a declining protocol used for transferring data and has in large part
been replaced by World Wide Web (WWW) browsers. FTP is used for uploading (sending) or downloading (fetching)
data and does not provide security or encryption. FTP requires client software, many of which support the use of
proxies. FTP, an older protocol with plain text authentication, has been replaced with Secure File Transfer Protocol
(SFTP) within many organizational networks. SFTP encrypts both commands and data, preventing passwords and
sensitive information from being transmitted in clear text over the network. Basically, SFTP can utilize the inherent
authentication and encryption capabilities of the SSH protocol. See SSH FTP and FTPS.
