How can I implement security headers in my web application?

Implementing security headers is crucial for protecting your web application. You can start by adding headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options. Would you like to know how to set these headers in your server configuration?

Yes, please explain how to set the Content-Security-Policy header.

To set the Content-Security-Policy header, you can add it to your server configuration. For example, in Apache, you can use: Header set Content-Security-Policy "default-src 'self';". This restricts resources to be loaded only from the same origin. Do you need help with a specific server type?
