Microsoft has enabled the Windows Firewall, previously referred to as Internet Connection Firewall, by default in Vista. This was the case starting with Windows XP Service Pack 2.
You probably know the benefits of having a hardware firewall device on the border of your network between your workstations and the Internet. To add another layer of defense, you can also use a firewall on your individual computers. To help you, Microsoft has integrated a Windows Firewall software package into Vista.
Enabling the Windows Firewall is a simple process. You can easily identify whether it is enabled because a red border will surround the Local Area Network icon when this feature is turned on.
To enable Windows Firewall in Vista:
- Click Start and click Control Panel.
- Click the Security option.
- Click Windows Firewall.
- The Windows Firewall should be listed as “on”. If not, click Change Settings.
- Click On (recommended).
- Click OK.
At this point, the software will be active, using the default configuration settings to protect your system from intruders.
