Protecting a WordPress websites against DDoS attacks is not easy. Most experts believe that minimizing threats of DDoS attacks are the best thing to do in this regard. Fixing vulnerabilities in WordPress websites can help you tackle this issue.
Here are some of the ways you can adopt for the same:
No XML-RPC Functionality
The XML-RPC functionality is enabled by default. It has been in practice since the launch of WordPress 3.5. It is known to offer services such as trackbacks, pingbacks, and many more. However, these are quite vulnerable. The functionality can also be exploited for sending HTTP requests to any target website. There may be times when many thousands of WordPress websites get compromised. Requests may start pouring into a target website autonomously. Under such a situation, a DDoS attack may occur.
The best thing to do is to remove the XML-RPC functionality. Make sure you do this on all of your WordPress websites. This is important to ensure they cannot launch a DDoS attack using trackbacks and pingbacks.
Add the code given below into your .htaccess file:
# START XML RPC BLOCKING
Order Deny, Allow
Deny from all
# FINISH XML RPC BLOCKING
As an alternative, you can also use a plugin such as Disable XML-RPC Pingback for disabling both trackback and pingback functionality. This will keep other XML-RPC functions intact.
Upgrade WordPress Version
It would help if you focused on upgrading the WordPress version very regularly. One of the significant advantages of using WordPress is that it periodically updates security developments by enthusiastic contributors and a thriving community.
Make sure the following is upgraded regularly:
- MySQL version
- WordPress installation
- OS version
- WordPress plugins
- WordPress themes
- PHP version on the server
- Apache version
- Other script or software you use
Apart from updating WordPress, make sure all of the server-side updates are maintained well.

Reach Web Host
This is important. It would help if you got in touch with web hosts to talk about network hardware and servers. These need to be updated very regularly with the latest software versions. Make sure you discuss the type of security measures offered by the web host. For instance, Cloudways ensures several security features to its clients. The best part is that these features are provided without any additional costs. Some of the features offered by Cloudways include access to SFTP & SSH, operating System Firewall, application Level Firewall, Server Cloning, Auto backups, Auto-Healing, Application updates and notifications, Auto-updates, and patches of the OS and services, and Dedicated IP on Cloud Server.
This is a great way to add security to websites. When you configure a security plugin, you add a strong layer of defense to your WordPress website. Freelance front-end & WordPress developers will prefer using WordFence. It can dynamically monitor and prevent DDoS attacks on WordPress websites of all types and sizes.
Undoubtedly, security plugins tend to squeeze out a lot from web servers. This is because the scripts use large numbers of resources to keep tabs on your WordPress website’s various security threats. A Cloudways maintained server could easily handle resources required by security plugins.
Quora is an excellent medium for getting tips and suggestions on WordPress. Recently, one of the information security analysts, Minton Navas, was ask about the best way to protect WordPress websites against DDoS attacks. According to Navas, hardening the security of websites is the best way to ensure protection. Particular attention should given to WordPress websites. This is important for reducing threat levels related to DDoS as it cuts down on the number of susceptible WordPress resources accessible to the attacker.
