Why Do I Need to Worry About WordPress Security?

WordPress Security is one of the major concerns for everyone right now. Each year thousands of WordPress built websites get hacked, lose data, lose access to the website.

Let’s face it. There is no 100% secured system in the world. That is why you need a WordPress Security Guide!

There will always be some risks in your system. However, you must take preventive actions, mitigate risks to make sure your website is not vulnerable to attacks.

Most websites usually get hacked due to poor system administration, not using the latest WordPress version, using weak username/password among many other cases.

Attacks on WordPress Sites Have Risen Significantly in the last few years

Industry renowned security firm Sucuri has published a detailed analysis of the most attacked Content Management Systems. Unsurprisingly WordPress came on top by absorbing about 80% of the total attacks.

So it is wise to concentrate on your WordPress security before it is too late. Nothing is worse than waking up in the morning and discovering that you do not have to access your own website. Our WordPress security guide will help you to stop attacks and fix vulnerabilities on your website.

This post will provide you some of the best WordPress security tips to reduce the vulnerability of your WordPress installation.

Ultimate WordPress Security Guide

We have divided our WordPress Security Guide into a few parts.

Database Security

A database is the single most important thing when building a new website. So when you are creating a new website, you must rethink about the security measures you are taking to secure your database. Many of us prefer the easiest way to install WordPress from cPanel. If you are concerned about security, we will always recommend you to install WordPress manually by creating the database first and adding a database user.


  • Tip: Use a unique database name. For example, if your website name is “myschool.com” then always choose something that is not related to the domain name.
  • Add number with the database name to make it more secured.

Database User Security

While adding your newly created user, it is wise not to allow ‘Drop’ permission for the database user. Even if someone gets access to your database, they will not be able to drop the table. This will ensure tight security for your website.

Preventing Brute Force Attacks on WordPress Website

A small script can be used to run Brute Force attack on your site. Hackers nowadays use different methods such as Socks/Proxy/VPN/Tor to keep attacking websites. Hence, we need to use CAPTCHA to stop these brute force attacks.

  1. If you want to stop plugin updates from admin panel add this code to your wp-config.php file
define('DISALLOW_FILE_MODS', true);

2. If you want to stop any changes from the admin panel, add this code to your wp-config.php file. This is particularly helpful when a site gets hacked.

3. If you want to stop several types of script injections to your website, add this code to your .htaceess file.

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{QUERY_STRING} (\<|%3C).*script.*(\>|%3E) [NC,OR]
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
RewriteRule ^(.*)$ index.php [F,L]

4. Use Strong Username/Password. It is so obvious but still people use WordPress username as “admin” and password as “admin” or “1234456”. Please DO NOT!

If you are using WordPress username admin, then immediately create a new user with a new username, make the new user Administrator and delete the old “admin” account.
