To be able to keep your website up and running, and away from security threats, one must know how to secure a WordPress site.

Importance of Website Security

If your website gets hacked, it can get you into some serious financial trouble. The personal information like credit card numbers of your customers, or your confidential material can get stolen. The website can go down for a significant number of hours, which can hurt your business.

In worst cases, you can also find yourself in a ransom situation, where hackers regain access to your website on a frequent basis.

If your website runs your business and you depend on it financially, then you should pay special attention to your website security. It is the responsibility of the business owner to protect their physical store building and for an online business this responsibility gets even more important..

WordPress Updating

Even a basic WordPress website comes with thousands and thousands of plugins and themes. Every theme you install on your website will come with compatibility with many themes. They usually come from third-party developers, which means that they are regularly updated and released. Keeping your website and its plugins updated will also keep the security of your website updated.

User Permissions and Strong Passwords

One of the most common and popular WordPress hacking attempts that hackers make from around the world are using stolen passwords. One can make things difficult for the hackers by making use of strong passwords, which are unique for your website and is not used on any other accounts of yours. You should keep your cpanel passwords unique from your FTP accounts, WordPress hosting account, database, and other professional accounts like email addresses.

Beginners like to use easy and repetitive passwords, as they don’t find it hard to remember or usually don’t think about the hacking situation that often. You don’t have to remember strong passwords anymore. As there are plenty of professional password managers available that will help make this job easier. You can opt for Keychain Access if you are using iOS operating system, or other paid and reliable versions for other devices.

It is also a good practice to avoid giving people your backend passwords unless you have too. If you have a team or guest authors with access to your website, you can change their user roles and abilities to act on the WordPress backend.

Role of WordPress Hosting

The most important role played by your WordPress site is by its hosting service. You can pick reputed and shared hosting providers like BlueHost or SiteGround. They take special measures to protect their servers against common threats.

If you are opting for shared hosting, you basically share server resources with other customers. This means that you are at risk of cross-site contamination, which indicates that a hacker that hacks a neighboring site can access yours too.

You can opt for managed WordPress hosting providers that are a more secure platform for your website. They also offer automatic backups, WordPress updates, and more advanced configurations for security.

Changing “admin” Username

A WordPress admin username is called “admin” by default and majority of users fail to change this name, as they don’t think it can pose a security threat. A hacker can take this as a sign and make hacking attempts more aggressive.

Disabling PHP File Execution in Directories

This is also another way to harden your WordPress security is to disable PHP file execution in some particular directories.

Paste the following code in the text editor:

<Files *.php>
deny from all
</Files>

Save this file as .htaccess and upload it to wp-content/uploads/folders on your site while using FTP client.

Limiting Login Attempts

WordPress allows users to try and login for a given number of times. This leaves the site vulnerable to several repetitive attacks, where hackers constantly try to crack passwords by logging with different combinations.

This error can be easily fixed by limiting the number of failed login attempts that a user can make. If you are using a firewall, it will automatically consider such attacks.

To limit the number of login attempts, you have to install and activate the Login LockDown plugin. Once activated, you can visit the Settings and then Login LockDown to setup the plugin.

Changing Database Prefix

WordPress uses wp_ as a default prefix for all the tables in a database. If a WordPress site is using the default database as a prefix, then hackers can easily guess the table name and hack their agendas. Changing this is recommended.

WordPress Admin and Login Page Protected by Password

The very common action taken by hackers is that they can request your wp-admin folder and login page without any restrictions. This allows the hackers to run DDoS attacks. Now you can add additional password protections on the server side, which will effectively block such requests.

Disabling Directory Indexing

Directory browsing is a common gateway used by hackers to know more about the files and their vulnerabilities. Other people to take a peep into your files and even copy images can also use it. To avoid this, you need to connect to your website via FTP and locate the .htaccess file in your root directory.

Add the following given line at the end of a .htaccess file.

Options –Indexes

Disabling XML-RPC

When XML-RPC is enabled by default, the connecting WordPress site with web and mobile apps can get connected. It is a powerful feature in WordPress and can also imply that it is a brute-force.

Let’s say a hacker wants to attempt an access to your backend. They will try 500 different passwords, with 500 unique login attempts. At some point the login plugin will lockdown the attempts and block the hacker.

If XML-RPC is enabled, system.multicall function can be used to try 1000s of unique passwords in just 50 requests.

If you are not using XML-RPC, then disabling it is recommended.

Keeping your website’s security fully checked and in the best condition is necessary to keep your business up and running. With these simple hacks, you can easily protect your site from aggressive hacking attempts.
