Abstract
A digital certificate incorporated within a communication is received from a server associated with a host name. Resource records associated with the host name are caused to be queried for a list of certificate authorities. In response to causing the resource records to be queried, the list of certificate authorities is received. A certificate authority is identified within the received digital certificate. The identified certificate authority is compared to the received list of certificate authorities. A determination is made, based on the comparison, that the identified certificate authority is included in the received list of certificate authorities.
