SFTP - OpenSSH FTP Server on Ubuntu 18.04 LTS

SFTP, which stands for SSH (or Secure) File Transfer Protocol, usually runs on port 22 (but any port you want can be assigned), and is a way to transfer files between machines over Secure and Encrypted Connection, unlike FTP. which transmits data over an insecure and unencrypted connection.

SSH-2 is integrated with SFTP, which provides a fully encrypted transport layer over which you can execute SFTP commands as needed, as well as transfer files all over the place, which is its main use.

SFTP also protects against password sniffing and man-in-the-middle attacks. It protects the integrity of the data using encryption and cryptographic hash functions, and authenticates both the server and the user.

With SFTP, files are transferred over the network through the main control connection, instead of opening a new separate connection for transfers such as FTP. As a result, the benefits of this method are a single, efficient, and secure connection passing data through the firewall, resulting in faster transfer speeds.

One of the most overlooked benefits of using SFTP and its underlying protocol is the ability to deliver files with all their attributes if needed, including permissions, time/date, size, and other information not available with FTP.
