A New Architecture for Conflict-Free Firewall Policy Provisioning

Overview Firewalls constitute the primary line of network defense. A network may have multiple firewalls - one at the organizational level and another at each of the departmental levels, with each firewall working in accordance with the global organizational security policy. The firewalls are so configured that each department's intranet receives or transmits only the traffic that it needs and the traffic not required is blocked by the respective firewall. Firewall policy addition, deletion and modification becomes a difficult task in such a complex multiple firewall and dynamic environment where the ever changing organizational traffic needs leads to continuous changes in firewall configuration, increasing the chances of policy conflicts among different firewalls in network hierarchy.
