Content Security Policy: A Developer's Guide to Blocking XSS Attacks
Content Security Policy (CSP) is an HTTP header that tells browsers which sources are trusted for loading resources like scripts, styles, and images.

Implementing CSP requires careful whitelisting of trusted domains, but offers a powerful security layer against injection attacks.
