Abstract
Upon receiving malware detection rules that are to be identified with respect to an input traffic stream, a sequence of state definitions are generated for each of the rules. The state definitions for each rule correspond to respective segments of the rule and specify conditions under which a state machine is to transition between search states corresponding to those segments, at least one of the segments corresponding to multiple characters within the input traffic stream. A state machine transitions between search states corresponding to one or more of the rules in accordance with contents of the input traffic stream and the conditions specified by the sequence of state definitions.
