Windows Security System Components Overview
Among the new security features, the Windows Security Center automatically sets 
up a Windows Firewall on your Tablet PC to block unwanted access to your system 
over the internet and from other networks. The Windows Security Center system 
provides security alerts during startup and messages while running Internet 
Explorer. These messages are a normal part of the operating system. Microsoft 
provides information with these alerts to help you decide what action to take.
In addition, you can set up the firewall to block all outside sources from connecting 
to your system (recommended) or can make exceptions to allow communications 
with a certain program. Within these settings, you can change the scope to specify 
a set of computers for which this port or program is unblocked.
