Abstract
Systems, methods, and software described herein manage server connection resets based on domain name server (DNS) information. In one implementation, a firewall may receive a reverse DNS request from a computing system and communicate a request to a DNS security service to determine whether a destination associated with the reverse DNS request is malicious. The firewall further receives a response from the DNS security service that indicates that the destination is malicious and, when the response indicates that the destination is malicious, communicates a reset command to the destination to reset a connection between the destination and the computing system.
