SFTP for Secure File Transfer

Here are a few excerpts from the article "Transfer files securely with SFTP" that I found over at Linux.com. The same underlying principle that FTP usage is evolving to more secure file transfer protocols such as SFTP certainly holds true for Windows PCs as well....

"File Transfer Protocol (FTP) was once the most widely used protocol for transferring files between computers. However, because FTP sends authentication information and file contents over the wire unencrypted, it's not a secure way to communicate. The more robust SSH File Transfer Protocol (SFTP) address this security concern by providing data transfer over a fully encrypted channel. You can use SFTP to transferring files securely over the Internet or any other untrusted network.

SFTP is a full-fledged file transfer protocol that implements all the operations found in FTP. SFTP runs as an SSH subsystem and works on standard SSH port 22 by default. It alleviates the need to open multiple additional ports on the firewall as in the case of FTP, where ports 20 and 21 need to be opened up for control and data traffic."
