摘要：Firewalls are a widely deployed security mechanism to ensure the security of private networks in most businesses and institutions. The effectiveness of security protection provided by a firewall mainly depends on the quality of policy configured in the firewall. However, designing and managing firewall policies are often errorprone due to the complex nature of firewall configurations as well as the lack of systematic analysis mechanisms and tools. This paper represents an innovative anomaly management framework for firewalls, adopting a rule-based segmentation technique to identify policy anomalies and derive effective anomaly resolutions. PolicyVis presented in this paper provides visual views on firewall policies and rules which gives users a powerful means for inspecting firewall policies.
