Delivering CSP via HTTP response headers (e.g., Content-Security-Policy) is strongly recommended over HTML meta tags for complete coverage.

CSP Best Practices

  • Restrict by Default: Start with strict defaults (`'self'`) and explicitly whitelist trusted external domains as needed for your application architecture.
  • Avoid Unsafe Directives: Minimize or eliminate the use of `'unsafe-inline'` and `'unsafe-eval'` to effectively block injection attacks.
  • Testing Policies: Consider implementing your policy using `Content-Security-Policy-Report-Only` initially to monitor violations without breaking site functionality.
