Firewalls White Papers
Design and Implementation of Firewall Policy Advisor Tools
Overview Firewalls are core elements in network security. However, managing firewall rules, especially for enterprise networks, has become complex and error-prone. Firewall filtering rules have to be carefully written and organized in order to correctly implement the security policy. In addition, inserting or modifying a filtering rule requires thorough analysis of the relationship between this rule and other rules in order to determine the proper order of this rule and commit the updates. This paper present a set of techniques and algorithms that provide automatic anomaly detection for discovering rule conflicts and potential problems in legacy firewalls, anomaly-free policy editing for rule insertion, modification and removal, and concise translation of filtering rules to high-level textual description for user visualization and verification.
