Firewalls White Papers
Network Firewall Policy Tries
Overview Network firewalls remain the forefront defense for most computer systems. These critical devices filter traffic by comparing arriving packets to a list of rules, or security policy, in a sequential manner. Unfortunately packet filtering in this fashion can result in significant traffic delays, which is problematic for applications that require strict Quality of Service (QoS) guarantees. Furthermore, as network speeds and capacities continue to increase, the processing time associated with filtering only compounds these delays. Given this demanding environment, new methods are needed to increase network firewall performance. This paper introduces a new technique for representing a security policy in software that maintains policy integrity and provides more efficient processing.
