Eric Byres suggested we take our back and forth from the blogs to the stage at S4x14. I had 5 minutes to explain why SCADA Apologist, as I claim Eric is, are a major impediment to progress in ICS security. Then Eric had 5 minutes to respond why he was a SCADA Realist and I’m the ICS tooth fairy (watch the video). We each had two more short back and forth chances to rebut and then extended the argument/discussion to the audience.

In the interest of fairness to Eric I won’t expand on my position in the blog. Just watch the video. I think both sides made their cases clearly; you can decide which is correct.
