Windows
The firewall function has existed since Windows
XP SP1, but at that time the protection function was simple and the configuration was single. Starting from Windows
Vista, the firewall function has become more and more perfect, and the firewall function has been significantly improved. No matter which third-party firewall is installed, the system comes with The system firewall should not be shut down, but should learn to use and familiar with it, which will be of great benefit to our system information protection.

The firewall that comes with Windows 8 is basically similar in function to Windows 7, and it also adds firewall settings for Metro applications. Here, we first review the related features saved from Windows 7.

Opening the general setting method of the firewall is relatively simple, and then open “computer
”——“control panel”——“Windows Firewall” .

For the underlying user, Windows has set up two sets of firewalls that do not affect each other for the dedicated
network
and public
network and guest accounts. This feature set is similar to Windows 7, allowing users to make settings based on different networks. The other settings are all on the left side of the ribbon, if you need to set up a network connection, you can click on the network and sharing center below the left side.

Looking at several general settings for Windows Firewall:

One, open and close Windows Firewall

Click on the left to enable or disable Windows Firewall .

It can be seen that the configuration of the private network and the public network are completely separate. There are two options in enabling Windows Firewall:

1, “block all incoming connections, This includes the program located in the list of allowed programs, which is the default, otherwise it may affect the use of some programs in the allowed program list.

2,<quo;Notify me when Windows Firewall blocks new programs> This item must be selected for personal daily use, so that you can make judgments at any time.

If you need to close, just select "Close Windows Firewall (not recommended)" in the corresponding network type, and then click OK.

Second, restore default settings

If your firewall configuration is a bit confusing, you can use “ restore default settings & rdquo; one, restore, Windows 8 consumer preview All network firewall configuration items will be deleted and restored to the initial state. For example, if the firewall is turned off, it will be automatically turned on. If the allowed program list is set, all the added rules will be deleted.

Three, allow program rules configuration

On the upper left side, "Allow programs or functions to pass Windows Firewall".

While everyone sees, it is to set the list of allowed programs or basic services. This function is basically the same as Windows 7:

1, there is no port configuration for regular configuration, so there is no need to manually specify the port. TCP, UDP protocol, because for many users do not know what these two things are, these configurations have been transferred to the advanced configuration, for ordinary users generally only use the application permissions to increase the rules.

2, the application's licensing rules can distinguish the network type, and support independent configuration, do not affect each other, which is very useful for users of dual network cards.

However, we may need to click the change settings button on the right side for the first time to operate (administrator privileges). If you need to know the specific content of a feature, you can click on the details below to view it.

If you are adding your own app licensing rules, you can add them via the "Allow another App…" button below, similar to the earlier firewall settings.

Select the name of the program to be added (if there is no list, click the "Browse” button to find the application, then click “Open”), the following network location types are private and public networks Two options, no matter what, we can go back to the previous interface and then set the changes, add.

If you need to delete after adding (such as the original program has been uninstalled, etc.), you only need to click the corresponding program item in the above picture, and then click the "Delete" button below, of course, the system The service item cannot be deleted and can only be disabled.

In addition, we can protect our computer

using the advanced settings of Windows Firewall. Click the Advanced Settings button on the left to enter the Advanced Security Windows Firewall.

The settings of the advanced security Windows firewall are more professional. Here are some simple introductions:

The advanced security firewall mainly has three important functions, namely creating or viewing an existing computer. Between the authentication rules, view and create firewall rules and view current firewall and IPsec policies and activities.

Create or view an authentication rule between existing computers: that is, connect security rules, if you need to create a rule, just right click on the "Connection Security Rule" in the tree on the left and click “New rule”.

View and create firewall rules: Create firewall rules that allow or block connections to specified programs or ports, and also allow connections only if the connection is authenticated, connections are from authorized users, groups Or computer. Includes two rules for inbound rules (rules that manage remotely initiated connections) and outbound rules (rules that manage locally initiated connections). By default, inbound connections are blocked, allowing connections to be made.

View current firewall and IPsec policies and activities: View security association information about the current application's firewall and connection security and active network connections.

In fact, in Windows 8, Windows Firewall can also be controlled and created with the new Windows PowerShell 3.0. I will not give a specific introduction here. Windows Firewall has many advanced features substantial, is free of many third-party firewall software are not available
