Firewall Builder consists of an object-oriented GUI and a set of policy compilers for various firewall platforms. In Firewall Builder, a firewall policy is a set of rules; each rule consists of abstract objects that represent real network objects and services (hosts, routers, firewalls, networks, protocols).

Linux kernel to include IPv6 firewall

Version 2.6.12 of the Linux kernel is likely to include packet filtering that will work with IPv6, the latest version of the Internet Protocol. Netfilter/iptables, the firewall engine that is part of the Linux kernel, already allows stateless packet filtering for versions 4 and 6 of the Internet protocol, but only allows stateful packet filtering for IPv4. Stateful packet filtering is the more secure method, since it analyses whole streams of packets, rather than only checking the headers of individual packets -- as is done in stateless packet filtering.

The latest version of the Virtuozzo server virtualization solution features several new enhancements, including a new Virtuozzo control center, automatic update utility, stateful firewall support and VPN support. The company also announced that Australian firm SMS Central has purchased Virtuozzo for installation in its data center.

Evaluating Your Firewall

Are you an administrator or security analyst who watches over a firewall with a hundred or more rules? Or perhaps a hired gun who must review a firewall with years of crusty buildup? Are you creating a test lab that involves a wide variety of networks, servers, and risks? If you're interested in enterprise-level firewalls, this article will help you make sense of common failures in processes and tools. We'll focus on enterprise-grade business and networking issues that affect firewalls. (Penetration studies and piercing firewalls from the outside will be covered in a later article.)

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one which exists to block traffic, and the other which exists to permit traffic.

A firewall is an organizationally and technical concept for the separation of networks, its correct implementation and constant maintenance. One piece that's often used is a piece of hardware that connects to networks the way as it's allowed in the concept. This piece of hardware is often called firewall-system/computer or in short firewall.
