Implementing Content Security Policy (CSP) in WordPress

Content Security Policy (CSP) is an added layer of security that helps detect and mitigate certain types of attacks, such as Cross-Site Scripting (XSS) and data injection attacks. Implementing CSP in WordPress can help protect your website and its users from malicious activities.

To implement CSP in WordPress, you can add the CSP header to your website’s HTTP response headers. This can be done by adding the following code snippet to your theme’s functions.php file:

function flashify_add_csp_header() {
    header( 'Content-Security-Policy: default-src 'self'; script-src 'self' https://cdn.example.com;' );
}
add_action( 'send_headers', 'flashify_add_csp_header' );

In the code snippet above, we are setting the default source to ‘self’, which means that resources can only be loaded from the same origin. We are also allowing scripts to be loaded from ‘self’ as well as a specific CDN domain.

It is important to test your CSP policy to ensure that it does not break any functionality on your website. You can use the CSP Evaluator tool to check the validity of your CSP policy.

Remember to regularly review and update your CSP policy as your website evolves and new plugins are added. By implementing CSP in WordPress, you are taking proactive steps to enhance the security of your website and protect your users from potential threats.

For more information on implementing Content Security Policy in WordPress, you can refer to the WP CSP plugin which provides an easy way to manage your CSP policy within WordPress.
