Configuring Security for the Basic Windows Firewall

The basic Windows Firewall provides essential firewall security for your computer. You can use the basic firewall to protect your computer from many types of attacks. In Control Panel, you can configure the basic firewall by clicking System and Security and then clicking Windows Firewall.

As Figure 15-14 shows, the main page in Windows Firewall provides an overview of the firewall configuration and status. You can use this information to tell at a glance whether the firewall is on or off, whether notifications are displayed when a program is blocked, and to which type of network you are currently connected. The network type determines which firewall profile is currently being applied. There are separate profiles for:

• Home or work (private) networks

• Public networks

• Domain networks

In the left pane are links for accessing management settings, including:

• Allow a program or feature through Windows Firewall

• Change notification settings

• Turn Windows Firewall on or off

• Restore defaults

• Advanced settings

Figure 15-14. Viewing the status of Windows Firewall

Clicking either "Change notification settings" or "Turn Windows Firewall on or off" opens the Customize Settings page. You can use the options on the Customize Settings page to turn the firewall on or off (see Figure 15-15) for each profile. To turn the firewall on, click "Turn on Windows Firewall." This setting allows the firewall to block incoming connections. To turn the firewall off, click "Turn off Windows Firewall (not recommended)." This setting turns the firewall off and makes your computer vulnerable to remote attacks through network and Internet connections.

When you are connecting to networks that are less secure, you may want to turn the firewall on and block all incoming connections to your computer. To do this, select the "Turn on Windows Firewall" option and the "Block all incoming connections..." checkbox. This setting ignores all settings in the firewall configuration and blocks every connection to your computer. You can turn off notifications by selecting the "Notify me when Windows Firewall blocks a new program" checkbox.

Back on the Windows Firewall main page, clicking "Allow a program or feature through Windows Firewall" opens the Allowed Programs page. This page, shown in Figure 15-16, allows you to control how programs communicate through Windows Firewall. Many Windows components commonly used for networking have exceptions listed in the Program or Port list. By default, you can view the configured exceptions but cannot make changes. To modify the settings, click Change Settings.
