Internet Connection Firewall
Today's always-on cable modem and DSL Internet access connections offer
unprecedented bandwidth to the home, but also leave the connected
computer or home network vulnerable to hacker attacks. The nature of
these attacks varies, but the goal is to gain access to individual computers
attached to the Internet. With this access, a hacker can browse the hard
drive and add or delete files, discover passwords and credit card numbers,
and set the system up to launch attacks on other systems or websites. As a
result, firewall protection from these attacks is increasingly required on
computers. Recognizing this need, Microsoft provides an integrated firewall
in Windows XP to provide immediate protection from outside access
attempts. When enabled, the Internet Connection Firewall provides basic
protection suitable for most home and small office users.
NOTE: Enabling the Internet Connection Firewall does not reduce the need
for virus-checking software.
The firewall is automatically enabled when you run the Network Setup
Wizard. When the firewall is enabled for a network connection, its icon
appears with a red background in the Network Connections portion of the
Control Panel. The Internet Connection Firewall can be applied to each
Internet connection on the computer. The firewall also provides basic
logging capabilities. Not all events that appear in the log are hacker attacks.
Many different types of harmless events can appear in the log, such as
routine checks by an Internet Service Provider to verify the presence of your
computer (pings).
