How to Secure the Joomla 4 site with HTTP Headers

Introduction

If you are building up your Joomla 4 website, one of the most effective ways to protect your site is using the HTTP Header plugin. With the help of the plugin, you can easily secure your data against cyber attacks by adding HTTP headers. Now, let’s find out how to secure the Joomla 4 site with HTTP Headers.

Secure the Joomla 4 site with HTTP Headers

Firstly, let’s log in to the administrator dashboard of your Joomla 4 site. After that, on the Toggle Menu, simply open System -> Plugins (in the Manage tab).

On the search bar, you just need to type System – HTTP Headers, then enter and click to edit the plugin.

Now, in the Plugin tab, you can freely configure the System – HTTP Headers.

• X-Frame-Options: In this section, you can decide whether your website can be embedded in other sites or web app by using iframes or not.
• Referrer-Policy: This section will allow you to remove the sensitive content from the referrer. It includes 9 options:

+ Disable

+ No-referrer: There is no referrer information sent.

+ No-referrer-when-downgrade: It will be a full URL unless accessing the HTTP page from the HTTPS one.

+ Same-origin: It is the only origin for the same site.

+ Origin: Only origin.

+ Strict-origin: When the security level is the same, it will be origin only.

+ Origin-when-cross-origin: It is the full URL for the same site, but just origin externally.

+ Strict-origin-when-cross-origin: It will be a full URL within the site. It will just origin if the protocol security level is the same, with no information from the HTTPS to the HTTP.

+ Unsafe-URL: It is the full URL.

• Cross-Origin-Opener-Policy: In order to prevent cross-scripting attacks, it allows to open external documents in a separate browsing group.
• Force HTTP Headers: It permits you to insert custom HTTP headers. Besides, you can use Feature-Policy to block unnecessary browser features.

Next, let’s move on to the second tab: Strict-Transport-Security (HSTS).

When you enable this section, you can configure the max-age value, subdomains, and preload. The HSTS will force the web browsers to just load your website via a secure connection. So, let’s enable it that works with SSL 301 redirects so that it will secure your site against HTTP downgrade attacks.

Finally, we will find out the Content-Security-Policy (CSP) tab. If you want to prevent web browsers from loading anything anything that is not in the header, let’s enable the CSP now.

After finishing the configuration to protect your site, don’t forget to save all your changes.
