Network Security relies heavily on Firewalls that manage network traffic, sometimes called the “Internet security” component. Firewalls are capable of filtering unwanted Internet traffic, and every time you enable network security, there are several settings you need to adjust. Here are the settings you should adjust to protect your network:

Enabling Network Security

Network security must be turned on for Windows computers to function properly. It’s worth noting that Windows 8 recommends having Network security enabled, but if you have your computer connected to the Internet, you don’t actually need to turn it on.

Network security must be enabled for each network adapter and each connection. Windows recommends that all network adapters and each connection are on by default and that no changes be made to the settings. You can easily change network security settings on a per-connection basis from the Control Panel.

Computer Settings

Open your Control Panel and click on Network and Internet. From here, you can see a list of network adapters, the networks they are connected to, and the IP addresses they are associated with. We have listed the IP addresses of each network adapter and the name of each connection here, so that you can easily see what network is connected to which IP address, if you want to protect your IP you can also use a VPN for this, click to find out more here.

If you don’t see your connection in the list, make sure you’ve enabled network security in the same way you would if it were your own computer. If you want to disable it entirely, just open Control Panel and click on your computer’s Network and Sharing Center. Click on the Manage Network Connections icon and you’ll see all network connections you’ve enabled Network security.

Windows Firewall

Windows firewall is available in Windows 8. There are several ways to configure firewall settings. The easiest way to configure Windows Firewall is to open your control panel, click on Internet Options, and then click on the Advanced tab.

As we mentioned above, the firewall should be on by default. If you want to turn it off for a specific connection, you can. You can do this from your Internet settings, though doing so is a bit complicated. If you open your Internet settings, click on the Local Area Connection tab.

Scroll down to the Add Firewall Rules button and select the type of firewall that you want to turn on. For our example, we will turn on Windows Firewall. Click on Next and then Finish. You will see a message stating that Windows Firewall has been turned off, click No to turn it back on.

Software Firewall

If you don’t want to use the Windows Firewall, then you can open your firewall settings and specify the software firewall for each network connection. We’ve already mentioned that Windows 8 is compatible with several different types of firewall, but there are even more. You can check your network adapter hardware and see what kind of firewall it is. If you have a router or switch, you can also check out a hardware firewall. In our example, we’re just using a Microsoft Windows Firewall, so Windows Firewall will work.

Firewall Protocols

The most commonly used firewall protocol is UDP. UDP is not controlled by the firewall directly. However, Windows Firewall also supports TCP. By default, Windows Firewall only allows UDP and TCP. You can change that behavior by right clicking the network connection and selecting Properties.
