摘要
In some embodiments, a method stores a plurality of identifiers for a plurality of rules. The plurality of rules each include a set of patterns, and a rule and a pattern combination is associated with an identifier in the plurality of identifiers. Information being sent on a network is scanned and the method determines when a pattern in the information matches a pattern for a rule. The method identifies an identifier for the pattern where the identifier identifies a rule and a pattern combination. Then, the method identifies the rule and the pattern combination based on the identifier. The set of patterns for the rule is found in the information based on determining that the rule and the pattern combinations for the rule have been found in the information.
