Firewall filtering rules have to be written, ordered distributed carefully order avoid policy anomalies that might cause vulnerability. Therefore, inserting or modifying any requires thorough intra- inter-firewall analysis determine the proper rule placement ordering firewalls. We identify all could exist single- environment. also present set of techniques algorithms automatically discover centralized legacy These implemented software tool called "Firewall Policy Advisor" simplifies management maintains security next-generation
