Big data doesn’t help us to create security intelligence! Big data is like your relational database. It’s a technology that helps us manage data. We still need the analytical intelligence on top of the storage and processing tier to make sense of everything. Visual analytics anyone?

A couple of weeks ago I hung out around the RSA conference and walked the show floor. Hundreds of companies exhibited their products. The big topics this year? Big data and security intelligence. Seems like this was MY conference. Well, not so fast. Marketing does unfortunately not equal actual solutions. Here is an example out of the press. Unfortunately, these kinds of things shine the light on very specific things; in this case, the use of hadoop for security intelligence. What does that even mean? How does it work? People seem to not really care, but only hear the big words.

Here is a quick side-note or anecdote. After the big data panel, a friend of mine comes up to me and tells me that the audience asked the panel a question about how analytics played into the big data environment. The panel huddled, discussed, and said: “Ask Raffy about that“.

Back to the problem. I have been reading a bunch lately about SIEM being replaced or superseded by big data infrastructure. That’s completely and utterly stupid. These are not competing technologies. They are complementary. If anything, SIEM will be replaced by some other analytical capabilities that are leveraging big data infrastructures. Big data is like RDBMS. New analytical capabilities are like the SIEMs (correlation rules, parsed data, etc.) For example, using big data, who is going to write your parsers for you. SIEMs have spent a lot of time and resources on things like parsers, big data solutions will need to do the same! Yes, there are a couple of things that you can do with big data approaches and unparsed data. However, most discussions out there do not discuss those uses.

In the context of big data, people also talk about leveraging multiple data sources and new data sources. What’s the big deal? We have been talking about that for 6 years (or longer). Yes, we want video feeds, but how do you correlate a video with a firewall log? Well, you process the video and generate events from it. We have been doing that all along. Nothing new there.

What HAS changed is that we now have the means to store and process the data; any data. However, nobody really knows how to process it.

Let’s start focusing on analytics!
