CAA Records (Certificate Authority Authorization)
CAA Records
Configured
(Restricts certificate issuance)
Current Issuer
Not Authorized
(Potential misconfiguration)
CAA Issues
- • CRITICAL: Current certificate issuer 'C=US, O=Internet2, CN=InCommon RSA Server CA 2' is NOT authorized by CAA records. Authorized CAs: certainly.com, amazontrust.com, amazon.com, pki.goog, digicert.com, hubspot.com, godaddy.com, sectigo.com, letsencrypt.org, awstrust.com, globalsign.com, amazonaws.com
Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • You have authorized 12 CAs - consider limiting to only the CAs you actively use
- • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
