Built-in firewall or Windows Firewall allows you to create advanced rules of network connections for powerful protection. You can create rules for Internet access to programs, white lists, restrict traffic to specific ports and IP addresses without installing other programs, firewalls for this. The standard interface allows you to configure the firewall ground rules for public and private networks. In addition, you can configure the advanced versions of the rules, including firewall interface with Advanced Security – this feature is available in Windows 8 (8.1) and Windows 7. Also, if you want to get more details, you can contact with the Windows tech support. And there are several ways to get an expanded version. The simplest of them – go to Control Panel, select Firewall Windows, and then, in the menu on the left click on the item Options.

Setting up a network profile in the firewall

Windows Firewall uses three different network profiles:
• Domain Profile – for the computer connected to a domain;
• Private Profile – Used for connecting to a private network, such in the office or at home;
• Overall profile – used for network connections to the public network (Internet, public access point Wi-Fi).

When you first connect to the network, Windows offers you a choice of public or private network. For different networks may use different profile: that is, when you connect your laptop to Wi-Fi in the cafe can be used overall profile, and at work – the private or the domain profile. Then, to configure profiles, click Firewall Properties Windows. In the dialog box you can set the basic rules for each of the profiles, as well as to configure the network connection, which will be used for one or the other of them. We should note that if you will block outbound connections, you will not see any notification of the firewall.

To fine-tune access, you can choose custom rules that can be applied in the following cases (just a few examples):

• You need to disable all programs, connect to a specific IP address and port to use a specific protocol;
• You must specify a list of addresses that are allowed to connect and deny all others;
• Configure rules for Windows services.

Setting specific rules is not particularly difficult, but it requires an understanding of what is being done. Windows Firewall with Advanced Security also allows you to configure the connection security rules related to authentication, but the average user will not need these features.
