FTP is a great protocol for accessing and transferring files, but it has the shortcoming of being a clear text protocol. In other words, it’s not secure to use over an internet connection, since your credentials and data are transmitted without encryption. The ‘S’ in SFTP stands for ‘Secure’ and tunnels the FTP protocol through SSH, providing the encryption needed to establish a secure connection.

  • How to setup an SFTP user account and group
  • How to connect to SFTP server via command line
