WordPress is the foundation of numerous websites globally, making it one of the most popular but also one of the most vulnerable content management systems online. A Web Application Firewall<\/a> (WAF) is one of the most useful solutions for security purposes since it acts as a barrier between the internet and your WordPress website.<\/p>\n\n\n\n

This guide outlines how a WAF can help WordPress websites, describes the main categories of WordPress WAFs, and brings specific step-by-step instructions on how to configure it, regardless of what plugin or WAF provider is used.<\/p>\n\n\n\n

Why Do WordPress Sites Need a WAF?<\/h2>\n\n\n\n

Most attacks against WordPress sites are automated; therefore, a single weak point, such as the use of an outdated plugin or a simple password, bears serious consequences. A properly set-up WAF plays the role of a gatekeeper by blocking known malicious IPs, preventing bot attacks, stopping brute-force logins, guarding against SQL injection and XSS, limiting the amount of threats coming to the server, and filtering out suspicious traffic before it reaches the WordPress installation.<\/p>\n\n\n\n

It is worth noting that two particular endpoints, \/wp-login.php and \/wp-admin\/<\/em><\/strong>, are often targets of various cyber attacks, such as bots attempting brute force attacks, credential stuffing, and username enumeration. However, even failed attempts to breach your website’s security can affect its performance through consumption of server resources; thus, deploying a worm is a fantastic way to block those attacks at the outset.<\/p>\n\n\n\n

Two Types of WordPress WAF<\/h2>\n\n\n\n

a) Cloud-based \/ Network-level WAF<\/h3>\n\n\n\n

The first type is a cloud or network-level WAF, when all incoming traffic is sent through the provider’s server before reaching your hosting company (for example, Cloudflare or Sucuri).<\/p>\n\n\n\n

\n The advantages of this type of WAF are that it protects your server from malicious traffic even before it gets there, is often coupled with a CDN, and does not utilize server resources. However, the downside is that in this case a DNS change is required for routing traffic through the provider.\n <\/p>\n<\/div>\n\n\n\n

b) Application-level \/ Plugin-based WAF<\/h3>\n\n\n\n

The second type is an application WAF or plugin-based WAF that serves as a plugin for WordPress (for example, Wordfence or Sucuri’s WordPress plugin). It is used within WordPress to filter out both the attack patterns and the malicious IP addresses in real time.<\/p>\n\n\n\n

\n The benefit is it does not require any modification of DNS records and offers substantial visibility of the activities happening on WordPress (including user behavior, changes in files, and attempts to log in to a platform). However, the downside is that the traffic is first received by your server before being filtered, which means a potential increase in load times for every webpage (while some plug-ins may have a significant impact on the loading time, it may be reasonable to check them out in advance).\n <\/p>\n<\/div>\n\n\n\n
