Recommendations
  • Consider adding 'preload' to HSTS for maximum security
  • Improve CSP by adding more specific directives and removing 'unsafe-inline'
  • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • Consider adding Permissions-Policy to control browser features

CAA Records (Certificate Authority Authorization)

CAA Records
Not Configured (Any CA can issue certificates)
CAA Issues
  • No CAA records configured - any CA can issue certificates
Recommendations
  • Implement CAA records to restrict which CAs can issue certificates for your domain
  • This adds an extra layer of security against unauthorized certificate issuance
  • Example: Add CAA record 'example.com. CAA 0 issue "letsencrypt.org"'
  • Consider adding 'iodef' record to receive security incident reports
