RE: Firewall Basics

I think it is prudent to have firewalls from 2 different vendors.  In my
opinion having different vendor's makes it harder for your network to be
penetrated because the attacker has to find out about the holes in two
vendor firewalls to successfully exploit your network.

If you have just one vendor, vulnerabilities in the first firewall will also
be present in the second and once you successfully penetrate the first, the
same holes can be exploited on the second.

Hi all:

I am designing a "service" network that is separate from our
"production" network.  Our web sites, email server, etc will be
utilizing this network; whereas, internet traffic and vpn traffic will
utilize the other.  My question is in regards to firewalls.  Currently,
I am using a PIX for my production network.  From what I have been
hearing, it is recommended to use two different firewall vendors in this
situation.  Is this a general consensus with all of you?  Or do you
think having another pix would be ok?  Thanks for any info!


Kind Regards,

Jennifer
