In accordance with one embodiment of the present disclosure, a method for determining the similarity between a first data set and a second data set is provided. The method includes performing an entropy analysis on the first and second data sets to produce a first entropy result, wherein the first data set comprises data representative of a first one or more computer files of known content and the second data set comprises data representative of a one or more computer files of unknown content; analyzing the first entropy result; and if the first entropy result is within a predetermined threshold, identifying the second data set as substantially related to the first data set.

System and method for statistical analysis of comparative entropy

A system, method, and computer program product are provided for applying a regular expression to content based on required strings of the regular expression. In use, all required strings included in a regular expression are identified, the required strings including strings required by the regular expression. Additionally, it is determined whether the required strings match content. Furthermore, the regular expression is applied to the content, based on the determination.
