Chapter 16 McAfee Total Protection 75
Optimizing Firewall security
The security of your computer can be compromised in many
ways. For example, some programs can attempt to connect to the
Internet as Windows® starts up. Also, sophisticated computer
users can trace (or ping) your computer to determine whether it
is connected to a network. As well, they can send information to
your computer, using the UDP protocol, in the form of message
units (datagrams). Firewall defends your computer against these
types of intrusion by allowing you to block programs from
accessing the Internet as Windows starts, allowing you to block
ping requests that help other users detect your computer on a
network, and allowing you to disable other users from sending
information to your computer in the form of message units
(datagrams).
Standard installation settings include automatic detection for the
most common intrusion attempts, such as Denial of Service
attacks or exploits. Using the standard installation settings
ensures that you are protected against these attacks and scans;
however, you can disable automatic detection for one or more
attacks or scans on the Intrusion Detection pane.
Protect your computer during startup
You can protect your computer as Windows starts up to block
new programs that did not have, and now need, Internet access
during startup. Firewall displays relevant alerts for programs that
had requested Internet access, which you can allow or block.
