<td>'''20'''</td><td>'''FTP'''<td>'''File Transfer Protocol (Data)''' - The File Transfer protocol provides a mechanism for transferring specific files between network connected computer systems (usually a Linux or UNIX based system). Transfer is typically performed using the ''ftp'' client which provides a range of commands used to connect to a remote server for the purpose of uploading or downloading files. Most modern web browsers also have the ability to browse and download files located on a remote FTP server. FTP uses TCP (rather than UDP) to transfer files so is considered to be a highly reliable tranport mechanism.</td>

The use of Secure Copy Protocol (''SCP'') and Secure File Transfer Protocol (''SFTP'') is strongly recommended in place of FTP.</td>

<td>'''22'''</td><td>'''SSH'''<td>'''Secure Shell''' - The Secure Shell is used to provide a secure, encypted, remote logon session to a remote host over a TCP/IP network. The original mechanism for remote access was the Telnet protocol. Because Telnet transmits data in plain text its use is now strongly discouraged in favor of the secure shell, which encrypts all communications, including log-in and password credentials. SSH also provides the mechanism by which files can be security tranfered using the Secure Copy Protocol (''SCP'') and is also the basis for the Secure File Transfer Protocol (''SFTP''). SSH also now replaces both the ''rsh'' and ''rlogin'' clients.</td>
