Using SFTP instead of FTP
It is much more secure to use sftp than compared to FTP, because ftp sends your passwords in plain text across your networks which can be very dangerous if someone was sniffing your network. sftp encrypts connections, just as easy to use for uploading files, downloading files changing permissions etc. You can also use SSH for connecting to your server and administrate it easily using it.
