Recommendations
  • • Consider adding 'preload' to HSTS for maximum security
  • • Significantly strengthen CSP directives
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking

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
