Frequently Asked Questions
What is Content Security Policy?
CSP is a security header that prevents XSS attacks by specifying which scripts, styles, and resources can load on your page.
What directives should I use?
Common directives: default-src, script-src, style-src, img-src, connect-src. Start restrictive and loosen as needed.
What does unsafe-inline mean?
unsafe-inline allows inline scripts/styles, which is less secure. Use nonces or hashes instead when possible.
How do I test CSP before deploying?
Use Content-Security-Policy-Report-Only header to log violations without blocking, then review reports.
