FTP Client - Using SFTP Instead Is Recommended
This page presents an overview of an FTP client and explains how SFTP provides the same functionality but securely and more robustly, and is easier to use and configure.
FTP Client Overview
An FTP client is a software application that allows logging in to a computer that runs FTP server software. Once a user has connected to a server and authenticated using a password, the user can then transfer files and folders to and from the server computer. The client functionality is embedded in most common web browsers, but is also available as a separate, dedicated software application for most common operating systems.
FTP Is Vulnerable to Identity and Data Theft
The FTP protocol is unencrypted and transmits passwords and data in the clear. Tools are widely available for capturing user names and passwords from the network. This is called password sniffing, and was a common attack already in the mid-1990s.
SFTP Is a Secure Alternative to FTP
The SFTP protocol and SSH have replaced FTP in practically all new applications. FTP should only be used with legacy systems that do not support SFTP. It is generally impossible to achieve compliance in regulated industries when using FTP.
The SFTP protocol also works across firewalls and Network Address Translation (NAT) automatically and without any special configuration.
