How Windows Firewall protects client Security

Windows XP, Vista, and Windows 7 all belong to the workstation operating system, which is the computer operating system installed in the user's work or entertainment. For ordinary users, it is best to enable Windows Firewall if you want to secure your computer from the network level. Windows firewall only blocks all incoming unsolicited traffic and ignores outgoing traffic from unsolicited requests.

If the network layer does not do any protection, the intruder will only know your computer administrator account and password, you can actively invade your system.

Now we introduce a software "Dameware mini Remote Control" that can actively invade the computer and can monitor and control the computer remotely to verify the role of Windows Firewall. The software can search dameware and download on the http://down.51cto.com website.
