I am designing a network for a small company and was wondering if using mixed
protocols helps provide any extra layers of security. I will be using a
wireless router to connect with two different computers and one of these will
have an additional network card (reference 1) through a switch to communicate
to a backup server. Would using the netbeui or ipx/spx protocol on the
network card mentioned above, called reference 1, give me any extra security
in this environment. Thanks for your time. My appreciation in advance.

I'm no expert, but I can't see how that would provide additional
non-physical security.

Eko,

Using additional protocols (IPX/SPX and / or NetBEUI) in addition to TCP/IP will
increase the complexity of your LAN, and of the computers there. Using IPX/SPX
or NetBEUI is frequently prescribed by some folks here, when they can't take the
time to figure out a TCP/IP problem. It's not a solution, it's a workaround.

If you use only IPX/SPX or NetBEUI to connect the two servers, you will be
protecting the backup server (only) from TCP/IP based (only) threats. All the
other computers will still be vulnerable to TCP/IP based threats, and the backup
server will still be vulnerable to non-TCP/IP based threats.

You'll still have to have security on the backup server, and with a custom setup
like that, you'll have a limited peer group for advice and support if you have
problems.

IMHO, using a custom setup like your idea may be a good idea when avoiding
specific, known threats, and only if you're prepared to work on your own when
you have problems.
