A very advanced security feature which can compete with any popular independent security software is new with Windows Server 2008 - the built-in firewall. It’s a police force for your system’s safety.
Microsoft means it when they call it an “advanced Windows firewall.” The amount of control we have over this firewall really has impressed me. What’s in the advanced firewall? Let’s find out:
1. Bi-Directional Filters
With the advanced firewall, it is now possible to set filters not only for inbound but for outbound traffic, too. For example, a network administrator may want to configure the new Windows Firewall with some set of rules that will block all traffic sent to specific ports/IPs and similarly block all incoming traffic from specified ports/IP.
2. Automatic Configurations
The advanced firewall has the ability to automatically configure rules for new roles that are added to the server, provided these are Microsoft applications. If you wish to run any non-Microsoft application on your server that needs inbound network connectivity, it will need to have rules created for it manually.
3. Firewall and Profiles
There is a domain profile, private profile, and public profile for the firewall. These different profiles allow you to group inbound and outbound rules and then apply this group to your computer (it could be your laptop or other PC). You can choose any combination of inbound & outbound rules and group them together to easily apply on any computer.
With such a groundbreaking firewall, in terms of its policies and rules configuration, it is evident that Microsoft has created WFAS while keeping the features of Microsoft’s ISA Server in mind. The firewall has more default rules than those in earlier versions along with other modern functionalities, indicating that it is surely an advanced firewall as claimed by Microsoft.
