Chris Hoff's response on his blog Rational Survivability makes me happy on two fronts. The primary reason I started this blog was to use this medium as an outlet for my ungrounded ego. The other was to participate in the Security Blogging community which was then catching up when I started  this blog 2 years ago. To get a response for my musings from brilliant minds such as Mike Rothman, Alan Shimel, Chris Hoff and others, gives me immense joy. May be this a good therapy for my undiagnosed attention deficit.

It does not matter if Chris is right or I am right. The outcome of IDS/IPS is all determined by random drift of market forces. There is no conspiracy to make IDS/IPS this way or that way. I would like to wrap up with a quote from Arthur Chandler : "We can tell when a technology has truly arrived when the new problems it gives rise  to approach in magnitude the problem it was designed to solve".

Alan Shimel's post on  "IDS - the beast that just won't die" triggered my hidden thoughts about IDS.

Rather than thinking about IDS as a piece of device/software that provides fancy features. Let me try to summarize some assertions about IDS: 

IDS can capture tons of intrusion events, there is so much of don't care events it is difficult to single out event such as zero day event in the midst of such noise.

It requires tremendous effort to sift through the log and derive meaningful actions out of the log entries.

IDS needs a dedicated administrator to manage. An administrator who won't get bored of looking at all the packets and patterns, a truly boring job for a security engineer. Probably this job would interest a geekier person and geeks tend to their own interesting research!

There are companies that do without IDS, and they do just fine. I agree with Alan's assessment that IDS is like a Checkbox in most cases.  Business can run without IDS just fine, why invest in such a technology?

Firewalls and other devices have built in features of IDS, so why invest in a separate product.

IDS is like Vitamins, nice to have, not having won't kill you in most cases. Customers are willing to pay for Pain Killers because they have to address their pain right away. For Vitamins, they can wait. Stop and think for moment, without Anti-virus product, businesses can't run for few days. But, without IDS, most businesses can run just fine and I base it out of my own experience.

Probably, I would have offended folks from the IDS camp. I have a good friend who is a founder of an IDS company, I am sure he will react differently if he reads my narratives about IDS.  Once businesses start realizing that IDS is a Checkbox, they will scale down their investments in this area. In the current economic climate, financial institutions are not doing well. Financial institutions are big customers in terms of security products, with the current scenario of financial meltdown, they would scale down heavily on their spending on Vitamins.

Running IDS software on VMware sounds fancy.  Technology does not matter unless you can address real world pain and prove the utilitarian value of such a technology. I am really surprised that IDS continues to exist. Proof of existence does not forebode great future. Running IDS on VMware does not make it any more utilitarian. I see a bleak future for IDS.
