VT,
My suggestion would be a compromise, test products on a dev network and
whittle down the contenders you will find showstoppers for certain products

Subject: Re: Intrusion Prevention requirements document
Another question for everyone,
When you brought in each vendor for evaluation, did you configure a test
network for them or did you use your production network? My 1st concern
is keeping my job :o) If I test in production, I could impact production
traffic. If I don't test in production, how can I best ensure that I
won't have problems with custom applictions, older IP stacks which could
be an issue if RFC compliance checks are done, etc.
The vendor answer is always, "don't turn on blocking and just monitor."
Is that a reality? I'd like some testimonials to this and some real life
instances of what has been done from unbiased sources.
Thanks,
VT
All,
I work on a team that manages signature and behavioral based intrusion
detection
systems today. We have been tasked with reviewing IPS (or whatever
vendor name
acronym you prefer) in '06. Our normal process is to put together a
base
requirements document to weed out vendors in the first round through a
paper
excercise and then bring in the best we can identify. My question is,
has
anyone developed a matrix that identifies key qualifiers in an IPS
solution
(e.g. in-line, fails open/closed, reporting features, etc.). If so,
could you
provide links or the documents?
If not, what categories are most significant to consider in your expert
opinions? What reasons did you choose the solution you have? What
would you
consider if you had to choose over again, etc?
Thanks in advance for your responses.
VT
