Firewall Builder GUI and policy compilers
Firewall Builder consists of object-oriented GUI and set of policy compilers for various firewall platforms. In Firewall Builder, firewall policy is a set of rules, each rule consists of abstract objects which represent real network objects and services hosts, routers, firewalls, networks, protocols. Firewall Builder helps user maintain database of objects and allows policy editing using simple drag-and-drop operations.
Preferences and objects databases are stored in XML format. GUI and policy compilers are completely independent. Support for a new firewall platform can be added to GUI without any changes done to the program, although new policy compiler must be written. This provides for consistent abstract model and the same GUI for different firewall platforms. Currently three most popular free firewalls are supported ipchains, iptables and ipfilter. Because of this, Firewall Builder can be used to manage firewalls built on variety of platforms including, but not limited to, Linux running ipchains or iptables and FreeBSD or Solaris running ipfilter.
