We have found this solution to be helpful, but it is not a guaranteed fix, and it is not our area of expertise.

We only offer this as a suggestion to help our customers gain a better understanding of their websites security.

PROTECTING YOUR FILES

It is commonly suggested that your .htaccess & wp-config.php file has the following file permissions: 444

SETTING UP YOUR .HTACCESS FILE

You will want to place this .htaccess file in your root web directory, commonly this is the public_html folder. This file should have 444 file permissions. Then you will want to add the following section above the “# BEGIN WORDPRESS” line in your .htaccess file.

Then you will want to add this to the end of your .htaccess file after the “# END WORDPRESS” line.

This last part of the .htaccess file is optional, and is only recommended if you wish to only be able to login to your wordpress website from a specific IP or specific range of IP addresses. If you do not know what your IP address is, you can go to vcn.com/ip or ipchicken.com to learn your Public IP. You would place this section of code right after the “# Custom WordPress Security” line.

Note: Make sure to replace (your.ip.here) with your public IP address

PREVENTING FILE-EDITING FROM THE WORDPRESS DASHBOARD

Please note that doing this step will prevent you from using the EDITOR feature in the wordpress dashboard to edit system files directly. You will still be able to edit pages and settings and the likes, but you cannot use the advanced editor when viewing plugins directly or themes directly. If you find that you lose access to something you used to be able to do in wordpress after enabling this, please go back and remove this code. To better protect against further exploits in your wordpress website, you can add the following code to your wp-config.php file. Do not put this at the end, but instead above the “/* That’s it! You stop editing here */” line which is close to the end but not quite.

PROTECTING YOUR SITE FROM DDOS / BRUTE FORCE LOGIN EXPLOIT

There is a known vulnerability in wordpress where someone can discreetly brute force your logins and get into your wordpress website without setting of alarms. More information on this can be found here. You can add the following code to this very end of this file wp-includes/functions.php :
