- Can a Firewall Protect Against Worm Viruses?
- Posted by Jeremy on August 14th, 2003
Hello. After being infected by and then liberated from two worms in one week
including the LuvSan worm, I was wondering if a personal firewall is able to
protect my computer from future worm attacks? Considering that worm viruses
can infect your computer JUST BY BEING CONNECTED TO THE INTERNET and NOT
even downloading anything, this poses a great risk to those of us who have
cable modems, satellite modems and DSLs, which provide a constant connection
to the internet as long as the computer is on. I know about several free
firewalls (Kerio, Zone Alarm, Sygate and Outpost) and that Comcast
high-speed internet users (like myself) get a one year free subscription to
McAfee firewall. So are firewalls a good protection from worms?
Having a cable modem, myself, I know that I can create an internet
connection icon in my system tray by going to (this is for Win XP Pro, by
the way) Control Panel > Network Connections > Open "Local Area Connection"
my connection through my modem APPEARS to get severed (and to reconnect I
simply open my internet browser and tell it to connect). Now, so that I can
protect myself while NOT using the internet, will disabling my connection
using that icon actually sever my connection to the internet (because I've
heard that sometimes you can still be connected to the internet and not know
it, like when you don't even have a browser window open you are still
connected) and therefore protect me from worms? If not, I suppose I can
always physically sever my connection by disconnecting my ethernet cord from
my computer.
Thank you.

possibly, but you need to keep around other protection aswell (like
keeping your os patched) since your software firewall can shut down for
any number of reasons... it could certainly provide you some breathing
room, though...
there isn't really anything new about the threat posed by internet
worms... getting the worm just by being connected isn't new...
not all by themselves, no... they have to be installed, configured,
patched, maintained, etc... a firewall is only as good as the person
maintaining it...
it *should* break the connection...
being connected definitely has nothing to do with the browser window
being open... it has to do with that connection...
that could work too... but if you disconnect using your 'icon' method,
you should no longer be logged on to your isp and should therefore not
be receiving any traffic... i'm pretty sure your isp authenticates it's
users to avoid providing service to those who haven't paid them any
money - i bet you even told the connection wizard to remember your
password for you to facilitate automagical logons and thus make
connecting simpler... if you're worried about becoming reconnected
automagically by accident, you could unplug your network cable or you
could just tell the connection not to remember your password so that
the connection can't authenticate at the isp side without you
explicitly entering the password...

Undoutedly, a good firewall will help you.
Seek "ZoneAlarm" in Google. It's free, and works pretty well. Just in this
moment I am seeing the Port 135 W32Blast attacks to my system being
rejected by my firewall. Dozens by hour.
Honest. ZoneAlarm is a quite good firewall.
