Disclosed is a method of evaluating membership in a membership set. The membership query system receives data to determine membership. A representative pattern is extracted from the data that may be of a predetermined length or of an arbitrary length. A learning mode of the membership query system defines the membership set as a membership signature. The membership query system then determines whether the representative pattern is a member of the membership signature by applying a membership function. In the context of cybersecurity, if the data is a member of a set of known good executable files, then the executable file may be allowed or installed. If the data is not a member of a set of known good executable files, then the file is flagged for further investigation. |
