Abstract
A network intrusion system for a protected network includes a ruleset module configured to receive metadata for rules. The metadata describes, for each of the rules, a set of associated network vulnerabilities. The ruleset module is configured to access vulnerability information describing a set of cumulative vulnerabilities that each is present in at least one network device within the protected network. The network intrusion system includes a rule management module configured to, for each rule of the plurality of rules: identify the set of associated network vulnerabilities described by the metadata for the rule, determine whether there is a match between any of the set of associated network vulnerabilities and the set of cumulative vulnerabilities, and, in response to determining that there is no match, transmit a first command signal to a network security module. The first command signal instructs the network security module to disable the rule.
