WINDOWS FIREWALL
One of the chief ways to prevent attackers from assaulting your computer is to place a firewall between your computer and an Internet connection While you can use a hardware solution, like a Cisco 3825 router, to protect your organizations, you can also use a software solution to protect individual computers In Windows XP, Microsoft introduced its own firewall product: Windows Firewall Like so many other parts of Windows, this application is improved in Vista Vista includes two different versions of the firewall: Windows Firewall and Windows Firewall with Advanced Security In a nutshell, Windows Firewall provides the same sort of support and features that the Windows XP firewall provided Windows Firewall with Advanced Security allows you to be a lot more granular with your firewall functionality Let s take a closer look at these two products and how you can use them in your organization NOTE You don t have to use Windows Firewall, but it s a nice feature in Vista If you prefer to use a third-party product, you can simply deactivate Windows Firewall and use the other product
Firewall Features
As you probably remember from Windows XP or Windows 2003 Server, Windows Firewall is installed and enabled by default It protects the computer by blocking incoming network connections (wired or wireless), allowing only designated exceptions for specific programs, services, and ports Windows Firewall can be accessed by selecting Start | Control Panel | Security | Windows Firewall When the product starts, you see a screen like the one in Figure 10-10
