摘要：Firewalls are core elements in network security. However, managing firewall rules, particularly, in multi firewall enterprise networks, has become a complex and error-prone task. Firewall filtering rules have to be written, ordered, and distributed carefully in order to avoid firewall policy anomalies that might cause network vulnerability. Therefore, inserting or modifying filtering rules in any firewall requires thorough intrafirewall and interfirewall analysis to determine the proper rule placement and ordering in the firewalls. 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 error-prone 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 rulebased segmentation technique to identify policy anomalies and derive effective anomaly resolutions. Policy is presented in this paper provides visual views on firewall policies and rules which gives users a powerful means for inspecting firewall policies.
