Abstract

A network security device has at least one Fully Qualified Domain Name (FQDN) access policy that permits traffic to flow to at least one resource associated with at least one FQDN. The network security device receives, from a managed endpoint device, a packet directed to the at least one resource associated with the at least one FQDN. The network security device obtains DNS information associated with the managed endpoint device and, based on the domain name system (DNS) information, substitutes a network address of the at least one resource into the at least one FQDN access policy to open a traffic flow to the at least one resource associated with the at least one FQDN. The network security device then provides the packet to the at least one resource associated with the at least one FQDN.
