I've noticed something lately and I wonder if anybody else has
experienced this. At a meeting recently, I was told by a number of
people that IDS/IPS is a "worthless waste of IT resources" and
"providing no real value to an organization." The speaker at this
particular meeting challenged me to say "what business goals did the
implementation of an IDS/IPS achieve?" I responded that an IDS gives
insight to what is happening on a network and provides critical data to
more effectively focus resources on real problems. An IPS builds a level
of trust and protection from intrusions as well as insight into the
function and behavior of a network. (Okay, it was a vanilla answer, I
admit.)

So this speaker then challenged me to come up with verifiable metrics. I
replied that he would have to define what metrics he wants? What does he
consider a "viable metric" for performance. He said "did they sell more
products, make more money?" I replied "why is that the only metric that
businesses can understand? A lot of complex things go into 'making
money' and IT operations is a small part of that. Marketing, strategic
vision, and many other factors have a much more profound impact on
'making money' than a single IT security solution. However, insight into
operations and security is a critical component of IT. How do you know
you have been broken into if you don't have any mechanisms to detect
those intrusions? There is clear value in investment in locks and
security cameras, why not have similar investments into the digital
equivalents."

This shut him up, for a while, but it highlighted a growing trend I am
noticing. It seems like there are a lot of people with an agenda right
now to shoot down the value of IPS/IDS technologies. IPS in particular
seems to be painted as a "marketing ploy." I also hear the story "they
bought and IDS and it just sat in a rack and did nothing" a lot
(usually from people who don't even know what an IDS does.)

What is happening here? Anybody have any idea why there is a growing
"anti-IDS" attitude. Is it the failure of IDS to produce value in an
organization? Is the Gartner "IDS is dead" report having THAT much
affect on the industry? Are the IDS vendors victims of their own
over-marketing? Am I a paranoid moron?

I am curious to hear other people's ideas on and strategies for dealing
with these objections.
