Incident Reporting
CAA Issues
  • CRITICAL: Current certificate issuer 'C=US, O=Internet2, CN=InCommon RSA Server CA 2' is NOT authorized by CAA records. Authorized CAs: pki.goog, sectigo.com, amazon.com, digicert.com, letsencrypt.org
Recommendations
  • Consider using critical flag (flags=128) for stricter CAA enforcement
  • You have authorized 5 CAs - consider limiting to only the CAs you actively use
