CAA Issues
- • CRITICAL: Current certificate issuer 'C=GR, O=Hellenic Academic and Research Institutions CA, CN=HARICA DV TLS RSA' is NOT authorized by CAA records. Authorized CAs: harica.gr, letsencrypt.org, pki.goog; cansignhttpexchanges=yes, ssl.com, comodoca.com, digicert.com; cansignhttpexchanges=yes
Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • You have authorized 6 CAs - consider limiting to only the CAs you actively use
- • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
