In this article, we will dive into the permissions-policy header in WordPress. This new security header provides website owners with a way to define which resources and APIs can be accessed by their website. We will explore how to implement this header in your WordPress site and how it can help improve your website’s security.
Enhance Your Website’s Security with Permissions-Policy Header in WordPress Using .htaccess File
The Permissions-Policy header is a security feature that restricts certain actions on a website, such as the use of the camera or microphone. In WordPress, you can add this header to your website’s htaccess file to enhance its security.
To add the Permissions-Policy header, add the following code to your htaccess file:
Header always set Permissions-Policy "camera=(), microphone=(), geolocation=(), payment=()"
This code will restrict camera, microphone, geolocation and payment actions on your website. You can change the settings based on your website’s needs.
Adding the Permissions-Policy header to your htaccess file is an effective way to protect your website from potential security threats, making it a recommended practice in web development.

What is the header permissions policy in WordPress?
The header permissions policy in WordPress is a security feature that allows site owners to control which resources are allowed to be loaded on their website. This policy is enforced via the HTTP headers sent by the server when a client requests a resource.
By default, WordPress sends a restrictive Content-Security-Policy (CSP) header that only allows resources from the same origin to be loaded on the website. This policy helps mitigate cross-site scripting (XSS) attacks by preventing malicious scripts from being loaded on the page.
However, some plugins and themes may require external resources to function properly, such as fonts, scripts, or stylesheets. To allow these resources, site owners can modify the CSP header by adding allowed domains to the default-src directive. For example, if a plugin requires resources from Google Fonts, the site owner can add ‘fonts.googleapis.com’ to the default-src directive.
It’s important to note that modifying the CSP header should be done carefully, as it can potentially weaken the security of the website. Site owners should only add domains that are trusted and necessary for the website to function as intended.
What is the ‘Permissions-Policy’ header?
The ‘Permissions-Policy’ header is a security-focused HTTP response header that can be used to control which features and APIs are available to web pages. It allows web developers to specify a set of policies that limit the risk of attacks such as cross-site scripting (XSS), clickjacking, and other types of code injection. The Permissions-Policy header is supported by modern browsers and can be set in the htaccess file for web development. This header is useful for managing web permissions and improving the security of web applications.
How can I include a content security policy header in WordPress?
To include a content security policy header in WordPress using the .htaccess file, you can add the following code to your file:
“`
Header set Content-Security-Policy “default-src ‘self’;”
“`
Explanation:
1. The first line checks if the mod_headers module is available.
2. The FilesMatch directive applies the Content-Security-Policy header to all PHP files.
3. The Content-Security-Policy header restricts which resources can be loaded on a web page.
Note: This code sets a basic default-src policy that only allows resources to be loaded from the same domain as the website. You may need to adjust this policy depending on the specific needs of your website.
How do feature policy and permission policy header differ?
Feature Policy and Permission Policy headers are both security measures that can be implemented through the .htaccess file in web development.
Feature Policy allows developers to limit or restrict certain browser features, such as geolocation, camera, microphone, and more. This policy works by sending an HTTP header that specifies which features are allowed, and which are not. By implementing this, website owners can protect user privacy and prevent malicious use of these features.
On the other hand, Permission Policy header is used to control what types of content can be loaded on a webpage, such as scripts, plugins, frames, and more. This policy provides a way to reduce the risk of cross-site scripting (XSS) attacks by blocking certain types of content from being loaded.
While both policies have different functions, they both serve as important security measures that can be implemented through the .htaccess file in web development.
How can I add the permissions-policy header to my WordPress website using htaccess file?
To add the “permissions-policy” header to your WordPress website using the htaccess file, you can follow these steps:
1. Open your .htaccess file located in the root folder of your WordPress installation.
2. Add the following code snippet at the beginning of the file:
“`
Header set permissions-policy “accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=()”
“`
3. Save the changes and upload the file back to your server.
This code adds the necessary header to your website, which defines the policy for permissions like accelerometer, camera, geolocation, etc. You can modify the permissions based on your website’s requirements.
Adding this header helps improve the security of your website by controlling access to sensitive data and features.
What are the default values for permissions-policy header in WordPress and how can I modify them in htaccess file?
The default values for the permissions-policy header in WordPress are:
accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=()
To modify these values in the htaccess file, you can use the following code:
Header always set Permissions-Policy "accelerometer=(self), camera=(self), geolocation=(self), gyroscope=(self), magnetometer=(self), microphone=(self), payment=(self), usb=(self)"
This code will set the permissions-policy header to allow these features only on the same origin. You can modify the values inside the parentheses to allow other origins to access these features as well.
Is it possible to set different permissions-policy headers for different pages or sections of my WordPress website using htaccess file? If yes, how can I achieve that?
Yes, it is possible to set different permissions-policy headers for different pages or sections of a WordPress website using the htaccess file.
To achieve this, you can use conditional statements in your htaccess file based on the requested URL. You can use the %{REQUEST_URI} variable to match the requested URL against a regular expression pattern and apply the relevant permissions-policy header.
For example, if you want to set different permissions-policy headers based on whether the requested URL contains the word “admin” or not, you can use the following code:
“`
# Set permissions-policy header for admin pages
Header set Permissions-Policy “geolocation=(),midi=(),notifications=(),push=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),speaker=(self),vibrate=(),fullscreen=(self),payment=()”
# Set permissions-policy header for non-admin pages
Header set Permissions-Policy “geolocation=(),midi=(),notifications=(),push=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),speaker=(),vibrate=(),fullscreen=(),payment=()”
“`
This code will apply a different Permissions-Policy header depending on whether the requested URL contains the word “admin” or not. Note that the regular expression pattern used in the If statement can be changed to match any part of the requested URL.
By using conditional statements in your htaccess file, you can set different permissions-policy headers for different sections of your WordPress website to enhance its security and protect your visitors’ privacy.
In conclusion, adding the permissions-policy header in WordPress can significantly enhance the security and privacy of your website. By using the htaccess file, you can easily add this header to your website and control the permissions for various resources such as camera, microphone, geolocation, and more. It’s important to keep your website secure and protect user data, and by implementing the permissions-policy header, you can take a step forward in achieving these goals. So, if you haven’t already, make sure to add this header to your WordPress website using the htaccess file.
