Abstract
A preprocessor used in conjunction with a network firewall is disclosed. The preprocessor creates a first index for identifying a plurality of filters installed in the firewall. The preprocessor maintains statistics including selected criteria and corresponding values for the installed filters. When the value for the selected criteria exceeds a threshold value, the preprocessor creates a second index and moves a subset of filters from the first index to the second index.
