Many users have listed the firewall as one of the necessary software, in contrast, the Windows 7 system with the firewall, in the appearance appears concise, in this article will introduce the next Win7 with a firewall use, interested friends can refer to the

In the Internet more and more insecure today, many users have the firewall as one of the necessary software, and the major security vendors in order to attract the attention of users, but also their own firewall to do a pattern times out. By contrast, the Windows 7 system has its own firewall, which appears to be concise in appearance, but after years of development and improvement, it is now fully in the system as a standard personal firewall.

　　A new way to start and repair

The Windows 7 Firewall is no longer required to create an empty MMC and add a snap-in in the startup mode than the previous version. Just click on the advanced settings in the left panel to connect "Start menu/Control Panel/system and secure/windows Firewall" to open the configuration interface of the firewall.

A big difference between firewall and antivirus software is that when users make improper settings, it is very likely that the system will not be able to access the network situation. When the user does not remember what settings have been made to prevent access to the network, or if some of the applications do not work correctly, you can restore the firewall configuration to the default state of Windows 7 by clicking Restore Defaults on the left, almost as a firewall version of "One-click Restore."

　　Customizing security rules for different environments

Users in the process of using the computer, the security requirements are different, such as the habit with notebook friends will often run to the public Wi Fi network such places to go to the Internet, then do not want any external connections to their computers, and in the office or the home LAN, In order to facilitate users on the LAN to transfer files or play together, do not like to have too high security rules, the firewall can be for different network environment to customize the settings:

Click "Turn on or off Windows Firewall" on the left side of the main interface to open the firewall's custom interface. In this tab, users can apply different security rules to the local area network and public network, and the users on both networks have the option of "Enable" and "turn off" two choices, that is, enable or disable Windows Firewall. When a firewall is enabled, there are two more check boxes to choose from. where "block all incoming connections" is very useful in some cases, when the user enters a less secure network environment, you can temporarily select this check box to prohibit all external connections, even if Windows Firewall is set to "exceptions" Services are also blocked, which provides a higher level of protection for computers in less secure environments.

Firewall personalization allows users to independently allow a program to communicate through a firewall, such as playing a network game on a computer that is not fully secure:

Click "Control Panel/system and secure/windows Firewall" in turn, and on the menu on the left clicks "Allow programs or features through Windows Firewall." After opening in the window you can see the common network software is displayed in the list, if you want to add other programs, just click on the lower right corner "allow another program" to set the program need to pass the firewall

Programs in the program list can be added manually to allow programs that are not in the list to select Browse to manually select the address of the program.

For a firewall, the inbound rules for the external network are the most important setting, open the Advanced Settings interface, right-click the inbound rule in a new pop-up window, and select New rule from the pop-up shortcut menu. This is an example of the automatic upgrade procedure for Thunder, if you are ready to prohibit the thunder of the automatic upgrade program to accept any data, in the pop-up "New Inbound Rule Wizard" interface will require users to select the rule type, users can select the application, port, service, select the "Application", select the Thunder folder under the " ThunderLiveUD.exe "file.

When you have finished selecting, continue to choose the connection to the network, Win 7 provides users with 3 ways to connect:

Allow connections: programs or ports can be connected to the network in any case.

Only secure connections are allowed: The program or port is allowed to connect to the network only if IPSec is protected.

Block Connection: Prevents the program or port from connecting to the network in any state.

After choosing "Block Connection", the Thunderbolt's automatic update can not work completely!
