Abstract
A method of assessing the quality of a network filter rule containing a wildcard includes determine an instantaneous entropy for the network filter rule based on string distances or instantaneous entropy between a plurality of wildcard matches for the network filter rule. The method further includes performing an action if the string distance or instantaneous entropy for the network filter rule crosses a threshold. The action being selected from disabling the network filter rule, flagging the rule as a low quality rule, generating a candidate rule based on a portion of the match having low entropy and a portion of the match having high entropy, or a combination thereof.
