Abstract
Systems and methods for rating of signature patterns are provided. According to one embodiment, a frequency of occurrence is determined by a network security system of each of multiple patterns within a pattern database containing a set of candidate patterns from which a set of patterns or sub-patterns thereof will be selected for inclusion within a pre-match list. For each pattern, the network security device determines whether a length of the pattern exceeds a pre-defined length; and, if so, cuts the pattern to generate multiple sub-patterns having the pre-defined length. A rating for each pattern or, as the case may be, each sub-pattern is then determined by the network device based on any or a combination of the frequency of occurrence of the pattern within the pattern database, the length of the pattern or the sub-pattern and a measure of redundancy within the pattern or sub-pattern.
