Does it hurt/help to have 2 firewalls running?

[Johnbear007]

Would it hurt to have the zone alarm and norton internet security firewall running at the same time?

For maximum security, unplug the CAT-5 cable from your computer and pull the power plug from your wall. Now you're secure. Go outside and read a book.

I'm not being paranoid, it's just that I am testing out the evaluation version of norton internet security, but don't want to take down my zonealarm, so I just want to know if it would hurt anything to run them together. So far it seems fine.

I'd say that both products hook into the operating system at a low level, hence the presence of one will affect the other in some way.

Of course, I may be totally wrong

 

[Johnbear007]

It doesnt seem like they are affecting each other at all, beyond asking each other for permission to access the internet

Yes, the practice can be detrimental. A firewall apliance as the gateway and a software firewall on your pc and u will be fine tho.

It's not a very good idea. If you have a properly configured firewall, there should be no need for a second one. Not to mention the resources two firewall's would take up.

How so?

As I said I dont need these two I am just testing Inet security and don't want to get rid of zonealarm well I do it

I've heard of and seen many people run software and hardware but never software and software.

Well for anyone that may care:

I've been running it for a day now with no ill consequences. Norton is picking up some tcp header attacks that zonealarm wasn't getting.

Are they both picking up the other things though? I would think that if one of them picked up an 'attack' and denied it, the other wouldn't see it since it would have already been dropped.

they should both pickup a outbound attempt to connect to the internet, but I would assume you are right for inbound blocked traffic.

Sure, but I can only assume that zonealarm wasnt detecting the scans... either that or it just wasnt alerting me of it which is very possible

the norton firewall has a neat tracker though that opens a java applet and pinpoints on a worldmap where scnas and attacks originate pretty cool
