Security 7-15

Design guidelines

Careful thought should go into designing a new filter set. You should consider the following guidelines:

■Be sure the filter set’s overall purpose is clear from the beginning. A vague purpose can lead to a faulty set, and that can actually make your network less secure.

■Be sure each individual filter’s purpose is clear.

■Determine how filter priority will affect the set’s actions. Test the set (on paper) by determining how the filters would respond to a number of different hypothetical packets.

■Consider the combined effect of the filters. If every filter in a set fails to match on a particular packet, the packet is:

■passed if all the filters are configured to discard (not for- ward).

■discarded if all the filters are configured to pass (forward).

■discarded if the set contains a combination of pass and discard filters.

Disadvantages of filters

Although using filter sets can greatly enhance network security, there are disadvantages:

■Filters are complex. Combining them in filter sets introduces subtle interactions, increasing the likelihood of implementation errors.

■Enabling a large number of filters can have a negative impact on performance. Processing of packets will take longer if they have to go through many checkpoints.
