In this article I am going to talk about how you can use Group Policy to control the firewall that comes out of the box with Windows but first I want to give you a bit of history of the evolution of host based firewall in Windows. Firewalls have long been around for year protecting internal corporate networks from outside attackers see image below. As a result of having the firewall turned off by default in there were a number of computer worms of which most notably were the Blaster worm and Sasser worm that spread like wildfire to pretty much any Windows computer that had not been specifically secured. As a result Microsoft decided to make a major change with how Windows XP was configured with the release of Service Pack 2. When users installed service pack 2 they were now prompted to turn on the firewall thus protecting them from malicious communications. To get around this issues end users would be prompted when an application wanted to open up a incoming port on the network. This was a good first step however creating a set of firewall rules using the native group policy setting under Windows Firewall was challenging at best as there most setting had to be configured manually. IT Admins now have much more granular control over how they can manage the firewall rules and they now have the ability to control both inbound and outbound communication as well as being able to selective enable rules depending on what network the computer is connected. Below I will go though an example of a IT administrator wanting to setup a default set of firewall rules for a Windows 7 laptop computers and with a rule to allow Skype when connected at home and on the Internet but not when connected to the domain. Normally in the real world you would have many more inbound exceptions however you should be able to use this as a guide to get you started to build your firewall rule setup specifically for your environment. First we will setup a reference computer with the firewall rule the way we want and then explore them so we can import them into a group policy. Configuring the firewall rules on the PC first gives us an opportunity to properly test the rules before deploying them to other computers. As you can see Skype has...

How to enable the Windows Firewall, even though Domain Policies are prohibiting you from enabling it Consider the following scenario: In order to avoid having connectivity issues, the Domain Admins decided that it would be best to fully disable the Windows Firewall. They did this by disabling the Windows Firewall in the Domain Policies which are pushed and enforced on your computer. This is of course not a recommended scenario, since it makes your laptop vulnerable for network attacks. Just like a sitting duck, waiting to be shot Even when you have local admin privileges, you cannot just enable the firewall again, since the configuration options are grayed out, as you can see in the following screenshot:. Now when you are connecting to an unsafe network like a hotel network or an airport wireless hotspot, you would want to enable the Windows Firewall to be more secure. Pushed Windows Domain policies are periodically pushed by the Domain Controller to your machine. Typically all these settings are stored in the Windows registry. So in order to remove this unsafe configuration when you are not connected to the domain, it is possible to remove the pushed Windows Firewall configuration from the registry so that you can enable your firewall. After you have rebooted, the Windows Firewall configuration options will no longer be grayed out. You are free to enable your firewall and to not allow any exceptions to the configuration. There is no real risk when you remove the key from the registry. The next time you are connected to the Windows domain, the policies will be updated and the key will be added again to the registry.
