6. Secure VSFTPD
It is important to secure your FTP server against unauthorized access. You can easily do that by modifying a few settings in its configuration file. VSFTPD comes with a default configuration file /etc/vsftpd/vsftpd.conf. First, we will take its backup.
$ sudo cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.bkp
Next, open the original configuration file using a text editor
$ sudo vi /etc/vsftpd/vsftpd.conf
Please note, although you can log into FTP server, you will not be able to transfer any files with it.
So change the following line

Further, we create a user list /etc/vsftpd.chroot_list and limit FTP access to only those users listed in that file.
So add the following line in VSFTPD configuration file to specify the location of user list file that we will be creating next.
Save and close the file.
Now create a user list file at /etc/vsftpd.chroot_list
$ sudo vi /etc/vsftpd.chroot_list
Add 1 user per line. Save and close the file
