A firewall is a wall that sets your computer on fire.
Simply put, the untrusted network (IE: the internet) is on the 'outside' of the Firewall, logically separating it from the trusted network, which you want to keep safe. In this way, you can think of the Firewall as the outer gates of your protected network.
Here are the top security measures. 1. Firewall 2. Antivirus 3.Network security Firewall: Firewall acts as a barrier and protects your system from external threats. Best firewall software would be Comodo personal firewall(personalfirewall.comodo.com). Antivirus : Antivirus software searches for, detects, prevents and remove software viruses, and other malicious software Network security: Network security is a combination of antivirus and firewall created with an aim to give complete protection from every side.
A DMZ or DeMiliterized Zone is something that has to be created on the firewall. If you want to setup a DMZ and only have one PC and one firewall, then it is pointless to have the firewall in the first place. If you are in a corporate environment and do not know how to access the firewall, then you should not be setting up your computer on a DMZ. If you have several PCs on your home network and can access your firewall, then you need to look at the documentation for your firewall and it will tell you how to configure a DMZ. It should be noted however that Steam currently does not support operation through a network DMZ. Quoting a steam tech support email: "If your machine is currently in a network DMZ, you will need to reconfigure your network to play through Steam."Typically, Gaming needs Steam and the only inhibitor is not the outbound, but rather the failure to port forwardSteam-1 27000--27015Steam-2 27020--27050to the gaming system's ip address (obviously it must be a static LAN address)
