Quick Reference

CSP: Start with strict policy, relax as needed. Use nonces for inline scripts (not 'unsafe-inline'). Report violations with report-uri/report-to. Separate policies for different pages if needed. Test in report-only mode first. Always include default-src 'self'.

Use When

  • Web applications
  • XSS prevention
  • Security hardening
  • Compliance requirements

Skip When

  • API-only services
  • Internal tools (low risk)
  • Static sites with no scripts
