Whatever happened to 10gb IPS? Jul 15 2010 07:16AM

There are lots of boxes now which can, or claim they can, perform
10Gbps or more inspection.

Some of that is marketing fluff, some of it is the real McCoy.

If you have a need for 10Gbps inspection or higher then you really
need to do your homework because the boxes you pay for go for lots of
money.  If you spend all that money on a solution which doesn't do IPS
properly or only do IPS properly well below the expected / rated /
claimed throughput - and I accept there are various approaches which
do work, and there are those which don't - then you're stuck with it
for the foreseeable future.

You need to do your homework seriously - check reviews, NSS reports,
anything you can lay your hands on.  Then, get your hands on a unit to
evaluate them.  And when you test these devices, make sure you put
them in a production environment (passively - I'm not that stupid) to
get them to inspect YOUR traffic.  Don't rely on sending a PCAP to
someone and getting results, because you don't know how they've tested
your traffic, or if indeed they have tested it at all, just run basic
traffic distribution analysis on it and chucked the resulting figures
into a program to see the theoretical throughput.

And don't just test for raw IPS throughput - although it's important -
make sure the stuff you throw at it is caught - make sure it's proper
attempts to exploit vulnerabilities not just Nessus / NMAP scans, make
sure your testing rig replays traffic properly and doesn't provide an
approximation of TCP traffic, and lots of other things which need to
be done properly to test the solution effectively.

Raw throughput is only one element.  If you don't get proper
inspection, then the things are essentially expensive doorstops.
