Abstract
Systems, methods, and software described herein manage traffic rules in association with fully qualified domain names (FQDNs). In one implementation, a domain name system (DNS) security service obtains a FQDN associated with a DNS request by a computing device. The DNS security service determines a first score for the FQDN based on trust factors associated with the FQDN and determines whether the first score satisfies one or more criteria. When the first score satisfies the one or more criteria, the DNS security service evaluates host posture information associated with an IP address in the DNS response for the FQDN, updates the first score to a second score based on the host posture information, and determines a traffic rule for the FQDN based on the second score.
