Introduction The Nature of Today’s Attackers The Firewall to the Rescue Types of Firewalls How a Firewall Works Host-Based Firewalls Network Firewalls Firewalls for Small Offices and Home Offices Firewalls for Enterprises Firewall Products Summary Firewalls are a key part of keeping networked computers safe and secure.All computers deserve the protection of a firewall, whether it’s the thousands of servers and desktops that compose the network of a Fortune 500 company, a traveling salesperson’s laptop connecting to the wireless network of a coffee shop, or your grandmother’s new PC with a dial-up connection to the Internet.Hybrid worms, in particular, have penetrated corporate networks through email systems, and then have spread quickly to unprotected internal systems.Applying host-based firewalls to all systems, including those behind the corporate firewall, should now be standard practice.Traditional firewall architectures protect only the perimeter of a network.

Today, worms and viruses initiate the vast majority of attacks.

Worms and viruses generally find their targets randomly.

As a result, even organizations with little or no confidential information need firewalls to protect their networks from these automated attackers.

If a worm or a virus does find a security vulnerability and compromises your system, it can do one of several things.

This article covers the design, deployment, and use of both network and host-based firewalls (also called personal firewalls).
