Click Stop to
stop the service and change the Startup type to Disabled to prevent it
from loading the next time Windows starts. Click OK and then do the
same for the UPnP Device Host. Close the Services window when
you??™re done.
Remote Desktop good, but only when you need it. The Remote Desktop
feature, described in ???Control Your PC Remotely,??? earlier in this chapter,
is enabled by default in the Windows Vista Business and Ultimate
editions. Unless you specifically need this feature, it should be disabled.
In Control Panel, open System and then click the Remote settings link
on the left. In the Remote tab of the System Properties window, turn off
the Allow Remote Assistance connections to this computer option, and
select the Don??™t allow connections to this computer option, beneath it.
Passwords good. Make sure each and every user account on your system
has a unique password. Even though you may not be concerned about
security among users, unprotected accounts can be exploited by an
attack over a network. See Chapter 8 for details.

Networking and
Internet
Firewall good, sometimes. Set up a firewall, as described in the next section,
to further protect your computer by strictly controlling network
traffic into and out of your computer.
Open ports bad. Finally, look for vulnerabilities in your system by scanning
for open ports, as discussed later in this chapter.
The Security Center and the Firewall
The Windows Security Center, shown in Figure 7-28, is a central page in
Control Panel used to keep tabs on the Windows Firewall, Windows
Defender, User Account Control, and automatic updating.
