Is it true that the SP2 Firewall only checks incoming, but not
outgoing? I recently uninstalled Norton Firewall and planning to
contiue with just the built in XP SP2 firewall. Am I in greater
danger now?
Please help in these issues, thanx in advance!
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 protect you from any Trojans or spyware that you (or
someone else using your computer) might download and install
inadvertently. It doesn't monitor out-going 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, Kerio, or Sygate are all much better than WinXP's
built-in firewall, and are much more easily configured, and there are
free versions of each readily available. Even the commercially
available Symantec's Norton Personal Firewall is superior by far,
although it does take a heavier toll of system performance then do
ZoneAlarm or Sygate.
