Illustrated guide to AES

Jess Moser posted the most awesome and entertaining illustrated guide to AES.

ZACON09

Looks like we finally have a conference for the people by the people.

ISSA 09

I spoke this morning about secuirty non innovation at the ISSA 2009 conference. The purpose of the presentation was to position security architecture as a support for business innovation. You know that SOA and BPM initiatived didn't ship with security included in the box, right? For those interested in the introduction video you can grab it from here.

DiscussIT Podcast

Stephan Buys and myself were recently invited to come and chat about Splunk on the DiscussIT Security Pubcast. Stephan has some really solid delivery experience and works for Exponant, the local Splunk partner in South Africa. I got to share a little about our forth coming SAP application. The podcast can be found here.

I noticed that they posted the wrong link for the mp3, you can grab the mp3 from here.

See you at Splunk live in Johannesburg.

Virtualization CIO round table

I see the CIO round table for April is now online. The usual fun was had, just a pity that there's not enough space to capture all good talking points.

Risk CIO round table

I participated in a CIO risk round table last year, I see the article is now online. Hat tip to Maverick for hosting yet another fun event.

Where's the Intelligence?

One of the most crucial and overlooked areas in information security is intelligence gathering. Let’s face it the guys who do this well are physical security practitioners. They know if they get this wrong someone could end up dead.

Intelligence informs us to make better risk management decisions. It buys us time and gives us an opportunity to react. Without it we end up making bad and potentially harmful decisions not to mention mistakes.

We've gotten better at identifying our assets and modeling threats, however we've made little head way in dealing with threat agents and the threats that they pose. They become vague and generalized assumptions.

In some sense rather than dealing with them, we've tried to outsource the problem with technology i.e. IDS, IPS, DLP, SIEM, etc. At best we now known when something bad happened but only if we were looking and if we knew what to look for. Problem is we can’t see much anyway because we’ve been encrypting anything that moves, oops! At least we'll be getting fewer alerts to action and the management reports are all green now.
But can we collect intelligence about threat agents and threats within the organization? Yes and we’ve been doing a good job in the application space for ages with behavioral systems i.e. fraud detection. But what about the rest of the stack? This has proven to be very problematic as anyone who’s ever tried to build an all encompassing log management system will tell you.

Indexing log events across the stack is a promising new paradigm. Although not a security vendor, Splunk have developed a technology that does just that. If you could index your landscape you could now ask it very interesting questions for example “show me all the users who accessed the network but didn’t log on via RAS or the access network”. We're literally sitting on volumes of useful intelligence that end up on tape.

We've been having a lot of fun with Splunk recently, we've developed a connector for SAP NetWeaver. It's going to be interesting to see how this new paradigm is exploited by security vendors and pracitioners.

Drop me an email at if you are interested in playing with the SAP NetWeaver application.
