Introduction

The built-in Windows Firewall having Advanced Security caters you the means and mechanisms for a very robust rule-based security mechanism. It is specially designed to operate on the ‘deny before allow’ principle as all good security software does. By using the Windows Firewall with Advanced Security, you can easily block or permit traffic to your servers on particular IP addresses, ports, and to particular programs and the base that on the originating system too.

Many times, when the need arises for more security than only opening or closing a few ports on the computer, you spend so many pennies on third-party firewall software or hardware. You do that without even realizing that there is already much power that is formed into the operating system on your system/computer. It is actually the truth. It might not serve extremely complicated needs, but it can serve various typical needs. Have a look how: Windows Firewall having Advanced Security is a crucial security constituent in Windows operating system. And it is closely combined with the operating system. It is the reason that it is installed and enabled by default. Out of the box, it is available with various pre-written rules that block most of the incoming traffic to a specific system. Since that is the case, there is no need to install anything or enable it, just settings have to be got tightened.

Once you install software that makes use of networking features such as Microsoft SQL Server or even IIS, they might automatically form new firewall rules and open fresh ports in the system. When you receive a prompt asking you if you want to permit or deny some software from opening a firewall port, it is what is happening. It is important that you keep yourself informed about what these programs are and what they are actually doing!

It would be really rare when you would create rules for outgoing traffic. In fact, you might carve out rules to avert outgoing traffic. You should review any type of rules that are established to permit traffic, both inbound and outbound and decide if that is really needed.

You can do it in one of two ways: you can launch it from the Administrative Tools folder of the Start Menu or can even do it from Control Panel. You can also go to the Windows Firewall settings right from”. Make sure that you are an Administrator user because only then you would be able to make changes.

Once you open the window, expand “Monitoring” item and see in “Firewall” for a list of currently applied policies. Irrespective of any other policies defined in the system, these would be the firewall rules that are presently active and affecting traffic to your computer.
