  • System, method and program for managing firewalls
    Patent number: 8640218
    Abstract: Computer system, method and program for managing a firewall. First program instructions identify a first rule of the firewall. The first rule specifies a permitted message flow through the firewall to or from an IP address of a computer. The computer resides on a network. Second program instructions identify a second rule of the firewall. The second rule specifies a permitted message flow through the firewall to or from an IP address corresponding to the network. Message flows through the firewall to all computers on the network are permitted pursuant to the second rule. Third program instructions delete the first rule from the firewall based on the identification of the second rule and the computer residing on the network. Other program instructions identify and delete stale rules which are not needed. Other program instructions automatically identify rules for a new server added to a cluster.
