FTPS is a common method of securing an FTP connection. File Transfer Protocol (FTP) was originally designed to allow users to browse directories and transfer files between computer systems. The problem is that the FTP protocol has no provisions for security, and all information, including usernames, passwords and file data, is transmitted unencrypted. So anyone on the same network can easily examine the data as it is sent between machines.

More Secure than FTP

Available in all versions
FTPS (FTP over SSL/TLS) solves this problem by first securing the connection using SSL or TLS encryption, before any user or file data is exchanged.
What Types of FTPS Exist?
There are generally two modes of secure FTP available:
- FTPS uses implicit SSL/TLS to establish a secure connection before the FTP session begins, very similar to HTTPS. Regular FTP commands are then sent over the secure connection and protected by the TLS/SSL protocol.
- FTPES uses newer FTP commands to explicitily upgrade an unencrypted FTP connection to a secure connection during the initial authentication step. The FTPES protocol is somewhat more firewall friendly that the FTPS protocol, and allows the server and client to negotiate different levels of encryption and integrity protection on the control and data channels.
Is FTPS the Same as SFTP?
Another method of establishing secure connections and exchanging files is called SSH File Transfer Protocol (SFTP), but despite the name similarity, SFTP is an entirely different protocol than FTPS.
