How do I use Content Security Policy (CSP)?

What is Content Security Policy and how do I use it?

Content Security Policy (CSP) is a security feature that helps prevent various attacks like Cross-Site Scripting (XSS). You can use it by adding a CSP header to your web server's response.

How do I implement CSP in my website?

To implement CSP, you need to define a policy in your HTTP headers. For example, you can add a header like Content-Security-Policy: default-src 'self'; to allow resources only from your own domain.

What directives can I use in my CSP?

CSP has several directives like default-src, script-src, style-src, and more. Each directive controls the sources from which content can be loaded.

Can I use CSP with inline scripts?

Yes, but you need to use the unsafe-inline keyword or a nonce/hash for inline scripts to be allowed. However, it's recommended to avoid inline scripts for better security.
