How to Protect Your WordPress Site with Header Security

WordPress is a popular content management system that powers millions of websites worldwide. Due to its popularity, WordPress websites are often targeted by hackers and malicious actors. One of the ways to improve the security of your WordPress site is by securing the header section. In this blog post, we will discuss the importance of securing the WordPress header and provide some tips on how to do it.

Why is the WordPress Header Important?

The header section of a website is the first thing that a browser displays when a user visits a website. It contains important information such as the website title, meta data, and links to other pages. The WordPress header is also the entry point for many attacks on WordPress websites. Hackers can use the header to inject malicious code into the website, steal user data, or redirect users to a malicious website.

Securing the WordPress Header

Here are some tips to help you secure the WordPress header:

  1. Remove the WordPress Version Number One of the easiest ways to secure the WordPress header is to remove the version number. The version number can be used by hackers to find vulnerabilities in your WordPress installation. To remove the version number, you can use a plugin or add the following code to your functions.php file:
function remove_wp_version() {
  return '';

add_filter('the_generator', 'remove_wp_version');
  1. Disable the REST API The REST API is a powerful feature in WordPress that allows developers to access data from WordPress sites. However, it can also be used by hackers to launch attacks on your site. To disable the REST API, you can add the following code to your functions.php file:
function disable_rest_api() {
  return new WP_Error('rest_disabled', __('The REST API has been disabled.'));

add_filter('rest_authentication_errors', 'disable_rest_api');
  1. Use HTTPS Using HTTPS is a great way to secure the WordPress header. HTTPS encrypts the data transmitted between the browser and the server, making it harder for hackers to intercept and steal sensitive information. To enable HTTPS, you will need an SSL certificate. Many web hosts offer free SSL certificates, and there are also many plugins that can help you set up HTTPS on your WordPress site.


Securing the WordPress header is an important step in improving the security of your WordPress site. By removing the version number, disabling the REST API, and using HTTPS, you can protect your site from many common attacks. Remember to keep your WordPress installation and plugins up-to-date, use strong passwords, and backup your site regularly to further improve your WordPress site’s security.
