Firewalls help improve the security of your computer. Windows Firewall limits the information that is sent from other computers to users' computers, which gives users more control over the data on their computers and for users or programs (including viruses and worms) that attempt to connect to their computers without an invitation. ) provides a defensive front.
If you are struggling to strike a balance between the increased security of enabling fire protection and the efficiency of maintaining the system, then I recommend reading an article by Master Michael Howard for some specific details. Michael showed us how any of your local configuration and settings of the group policy affects the firewall, and how the "netsh" command is used to accurately reveal the internal mechanics of the firewall.
Netsh is a command line script utility that allows users to display or modify the network configuration of a currently running computer locally or remotely. Netsh also provides scripting capabilities that allow users to run a set of commands on a given computer using batch mode. The Netsh utility can also save configuration scripts as text files for archiving or to help configure other servers.
The Netsh utility has been greatly enhanced in Windows XP Service Pack 2 and includes all the way to run new options. It can be seen from the results of the commands on the author's computer that the Netsh command is quite friendly.
How to start this command, you don't have to say it.
C:> netsh firewall show?
The following commands can be used to view the configuration of the firewall:
show allowedprogram –display the allowed program configuration
show config - show firewall Configuration
show currentprofile - displays the current configuration file of the Windows Firewall.
show icmpsetting - displays the ICMP configuration in the Windows Firewall
show logging - displays the logging configuration in the Windows Firewall
show multicastbroadcastresponse – Displaying the multicast/broadcast response configuration of the firewall
show notifications -Displaying the notification configuration in the Windows Firewall
show opmode -Displaying the operation configuration in the Windows Firewall
show portopening -Displaying the port configuration in the Windows Firewall
>show service - Display service configuration in Windows Firewall
show state - Display current status of Windows Firewall
Of course, if you want to configure the firewall precisely, use the following command:
netsh firewall set allowedprogram Edit Windows Firewall Allowed program configuration in
netsh firewall set icmpsettings ICMP configuration in Windows Firewall
netsh firewall set logging Edit logging configuration in Windows Firewall
netsh firewall set notifications Edit notifications in Windows Firewall
netsh firewall set opmode Edit operation configuration in Windows Firewall< Br>netsh firewall set portopening Edit port configuration in Windows Firewall
netsh firewall set service Edit service configuration in Windows Firewall
Master these powerful tools, we can configure the firewall to be much easier.
