Windows 7 system firewall operation Raiders

Now on the Internet is paying more and more attention to "security" in this regard, for security, the firewall is also the user in the user's installed essential software list. And the major security vendors have made their own firewalls full of tricks for the eyes of genetic users. In contrast, the Windows 7 system comes with a firewall that looks simple in appearance, but after years of development and improvement, it is now completely a standard personal firewall in the system.

New startup method and repair

In the startup mode, the Windows 7 firewall will no longer need to create an empty MMC and add a management unit, compared to the previous version. It's easier. Just click on the Advanced Settings Connection “Start Menu/Control Panel/System and Security/Windows Firewall> in the left panel to open the firewall configuration interface.

A big difference between firewalls and anti-virus software is that when users make inappropriate settings, it is very likely that the system will be unable to access the network. When the user does not remember what settings have been made to make the network inaccessible, or some applications do not work after the change, you can restore the firewall configuration to the default state of Windows 7 by clicking "Restore Default Settings" on the left side. Almost can be called the firewall version of the "one-click restore".

Custom security rules for different environments

Users have different security requirements when using computers. For example, friends who are used to carrying laptops often go to public Wi Fi networks. Such a place to go online, then do not want any external connection to access their own computers; in the office or home LAN, in order to facilitate users on the LAN to transfer files or play games with each other, do not like to have too high security Rules, fortunately, the firewall can be customized for different network environments:

Click on the left side of the main interface to "turn on or off the Windows Firewall"; open the firewall's custom interface, in this tab In the user, the user can use different security rules for the local area network and the public network respectively. The users in both networks have the option of “enable” and “close”, that is, enable or disable the Windows firewall. When the firewall is enabled, there are two checkboxes to choose from, where <;block all incoming connections> in some cases it is very useful when the user enters a less secure network environment Temporarily check this box to disable all external connections, even if the Windows Firewall is set to "Exceptions", the service will be blocked, which provides a higher level for computers in lower security environments. protection.

The firewall's personalized settings allow users to individually allow a program to communicate through a firewall, such as playing a network game on a computer that cannot be completely safe:

Click “ /System and Security/Windows Firewall", on the left menu click "Allow Programs or Features via Windows Firewall". After opening, you can see that the commonly used network software is displayed in the list. If you want to add other programs, just click on the bottom right corner and “Allow another program to run” to set the program that needs to pass the firewall

Programs in the program list can be manually added as allowed. Programs not in the list can be selected by selecting “Browse” to manually select the address of the program.

For a firewall, the inbound rules of the external network are the most important settings. Open the “Advanced Settings” interface and right-click on the “Inbound Rules” in the new window that pops up. In the shortcut menu that pops up, select the “New Rule” command. Here, the automatic update program of Thunder is taken as an example. If you want to prohibit the automatic upgrade program of Thunder from accepting any data, the user will be asked to select the rule type in the pop-up "New Inbound Rules Wizard" interface, the user can target the application and port. , service selection, after selecting “ application & rdquo;, select the "ThunderLiveUD.exe" file under the Thunder folder.

After the selection is completed, continue to select the connection method to connect to the network. Win 7 provides users with three connection methods:

●Allow connection: Program or port can be used under any circumstances. Is connected to the network.

● Only secure connections are allowed: Programs or ports are allowed to connect to the network only if they are protected by IPSec.

● Block Connections: Prevents this program or port from connecting to the network in any state.

After selecting "Block Connections", Thunder's automatic updates will not work at all!
