Detection and Resolution of Firewall Policy Anomalies

Abstract

Firewalls are the most widely deployed security mechanism to ensure the security of private networks in most businesses and institutions. The efficiency of security protection provided by a firewall mainly depends on the quality of policy configured in the firewall. Unfortunately, planning and managing firewall policies are often error prone due to the complex nature of firewall configurations as well as the lack of systematic analysis mechanisms and tools. In this paper, we represent an innovative policy anomaly management framework for firewalls, approving a rule-based segmentation technique to identify policy anomalies and derive effective anomaly resolutions.
