Home Networking - Firewalls

In building construction, a firewall is a physical barrier to help prevent the spread of a fire from one room to another. The home network equivalent is well named. A firewall can be software or hardware based and the main purpose of the firewall is to make life more difficult for dangerous programs or unauthorised users to access your system without your permission.

Firewall protection has two directions. In some cases, you want to prevent data and/or programs from leaving your computer. This helps prevent any virus you contract from spreading to other systems on the network or the Internet. In the more usual case, your firewall is configured to prevent unauthorized programs and visitors from accessing your system from the outside.

That unauthorised access can come from different sources, typically the Internet, but also other machines on your home network. A drive-by hacker with a wireless enabled laptop, for example, can access your network and implant a virus. Blocking certain types of access can make his job harder, even though his system is temporarily inside your network.

But blocking all types of traffic from all possible sources in both directions would defeat the purpose of having a network at all. So, network security always strives for a compromise between locking out and opening up. Where to strike that balance is sometimes a gray area.

However, there is a fairly standard list of items that anyone will want to focus on. Keep in mind, the two most common protocols used: TCP and UDP. TCP is bi-directional, UDP is a broadcast that doesn't require a two way connection. Though, UDP traffic can travel in either direction, such as when you ping. Opening up a port on your firewall often involves specifying both the number and the protocol.

The default idea should be to close anything you don't know you will need. This means only open a port or protocol in the direction you need and only once you're sure you need it. The default should be 'closed in both directions'.

In reality opening ports is seldom conducted by an inexperienced home but should be managed by an experienced engineer.
