Thanks for your help
Unless you're an exceedingly cautious and paranoid expert user, and no
one else ever uses your computer, you really should have better protection.
WinXP's built-in firewall is adequate at stopping incoming attacks,
and hiding your ports from probes. What WinXP SP2's firewall does not
do, is provide an important additional layer of protection by informing
you about any Trojans or spyware that you (or someone else using your
computer) might download and install inadvertently. It doesn't monitor
out-going network traffic at all, other than to check for IP-spoofing,
much less block (or at even ask you about) the bad or the questionable
out-going signals. It assumes that any application you have on your
hard drive is there because you want it there, and therefore has your
"permission" to access the Internet. Further, because the Windows
Firewall is a "stateful" firewall, it will also assume that any incoming
traffic that's a direct response to a Trojan's or spyware's out-going
signal is also authorized.
ZoneAlarm or Kerio are much better than WinXP's built-in firewall,
in that they do provide that extra layer of protection, are much more
easily configured, and have free versions readily available for
downloading. Even the commercially available Symantec's Norton Personal
Firewall provides superior protection, although it does take a heavier
toll of system performance then do ZoneAlarm or Kerio.
Firewalls and anti-virus applications, which should always be used
and should always be running, are important components of "safe hex,"
but they cannot, and should not be expected to, protect the computer
user from him/herself. Ultimately, it is incumbent upon each and every
computer user to learn how to secure his/her own computer.
