Network Profiles
Network profiles are important because you can use them to apply different collections of firewall rules based
on which network profile is active. A significant difference between Windows Vista and Windows 7 is that in
Windows 7, profiles apply on a per-network interface basis. This means that if you have one network adapter
connected to the Internet and another connected to your office LAN, different sets of rules apply for each
connection. The firewall in Windows Vista chooses the most restrictive network profile when a computerhas
connections to different network types and applies the
most restrictive set of rules to all interfaces.
Allowing Programs Through Windows Firewall
Windows Firewall allows you to configure exceptionsbased on programs. This differs from Windows Vista
where Windows Firewall would allow you to configureexceptions based on port address. You can still create
rules based on port address; you just have to do itusing WFAS, covered later in this lesson. You can also allow
specific Windows 7 features, such as Windows Virtual PC, through Windows Firewall. Feature rules become
available when you enable the feature using the Programs And Features item in Control Panel. To add a rule
for a feature or program, click Allow A Program Or Feature Through Windows Firewall item in the Windows
Firewall section of Control Panel. The figure showsa list of currently installed features and any programs for
which rules have been created as well as the profiles for which rules concerning those programs and features
are enabled.
File and Printer Sharing
This feature is used for sharing local files and printers with other users on the network. (Uses NetBIOS,
LLMNR, SMB and RPC)
