Spotting That DAM(n) FakeBy Adrian Lane
I awoke at 2:30am to a 90-degree bedroom. Getting up to discover why the air conditioning was not working, I found a dog pooped on my couch. Neatly in the corner – perhaps hoping I would not notice. Depositing the aforementioned ‘present’ in the garbage can, I almost stepped on both a bark scorpion and a millipede – eyeing one another suspiciously – just outside the garage door. After a while, air conditioning on and couch thoroughly scrubbed, I returned to bed only to find my wife had laid claim to all the covers and pillows. Since I was up, what the heck – I made coffee, ran the laundry, and baked muffins while the sun came up. I must admit I started work today with a jaundiced eye, and a strong desire to share some of my annoyance publicly.
As part of some research work I am doing, I was looking at the breadth of functions from a couple different vendors in different security markets. In the process, I noticed many firms have decided Database Activity Monitoring (DAM) is sexy as hell, and are advertising that capability as a core part of their various value propositions. The only problem is that many of the vendors I reviewed don’t actually offer DAM. I went back to my briefing notes and, sure enough, what’s advertised does not match actual functionality. Imagine that! A vendor jumping on a hot market with some vapor. Today I thought at least someone should benefit from my sour mood, so I want to share my quick and dirty tips on how to spot fake DAM.
First, as a reminder, here is the definition of DAM that Rich came up with 5 years ago:
Database Activity Monitors capture and record, at a minimum, all Structured Query Language (SQL) activity in real time or near real time, including database administrator activity, across multiple database platforms; and can generate alerts on policy violations.
So how do you spot a fake?
- If the product does not have the option of a kernel agent, memory scanner, or some equivalent way to collect all SQL activity – either on the server or inside the database – the product is not DAM.
- If the product does not store queries – along with their response codes – for a minimum of 30 days – the product is not DAM.
- If the product is blocking activity without understanding the
WHEREclause, or several query and metadata specific attributes, the product is not DAM.
- If the vendor claims ‘deep packet inspection’ is equivalent to DAM, they are wrong. That’s not DAM either. Do us a favor and call them on it. They probably aren’t even doing deep packet inspection, but that’s a different problem.
IDS, IPS, DLP, Netflow analysis, and other technologies can provide a subset of the DAM analysis capabilities, but they are not DAM. Use these four checks to see who is telling you the truth. Remember, we are just talking about the basics here – not the more advanced and esoteric features that real DAM vendors have included over the years.
Now I am off to the DMV – I figure that’s just the place for my current demeanor to fit right in.
