Certificate Transparency [RFC6962] offers a mechanism to detect misissued certificates, and once detected, administrators and CAs can take the necessary actions to revoke the mis-issued certificates.
When requesting a certificate, the administrator can request the CA to include an embedded Signed Certificate Timestamp (SCT) in the certificate to ensure that their legitimate certificate is logged with one or more Certificate Transparency (CT) log.
In the future, a browser may choose to reject certificates without an SCT, and potentially notify the website administrator or CA when they encounter such a certificate. This reporting will help detect misissuance of certificates and lead to their revocation.
A administrator, or another party acting on behalf of the administrator, is able to monitor one or more CT log to which a pre-certificate or certificate is submitted, and detect the logging of a pre-certificate or certificate that contains their domain name. When such a pre-certificate or certificate is detected, the CA can be contacted to to get the mis-issued certificate revoked.
