Abstract
Certificate detectors scan a network for certificate resource information and send the information to a certificate database. A correlation engine extracts and correlates this information. A ranker uses the information about the certificates and certificate authorities to generate and provide a security score and/or ranking. A requester may view the certificate ranking and/or and certificate authority ranking after passing a domain validation authorization. An Internet browser may obtain a security score and/or ranking for a certificate authority and, based on this information, may determine to trust or not trust some or all certificates issued by that certificate authority, or to require corroborating evidence before trusting a certificate.
