Abstract
A firewall rule evaluation service scores firewall rules based on characteristics of logical objects that fall within ranges of Internet Protocol (IP) addresses corresponding to the firewall rules. Firewall rule scoring criteria may cause scores to be assigned to individual firewall rules based on an inverse relationship to quantities of discrete Autonomous Systems as well as aggregate numbers of and/or severity scores for threat intelligence flagged IP addresses granted access by individual firewall rules. The firewall rule evaluation service may further determine firewall rule recommendations for replacing firewall rules spanning multiple IP prefixes for different Autonomous Systems with more narrowly defined firewall rules that precisely encompass IP prefixes corresponding to single autonomous systems or multiple related Autonomous Systems (e.g., Autonomous Systems operated by a single trustworthy entity).
