DEF CON 29 was the first year of Adversary Village, and I have opened it with the village kick-off talk.
I introduced what the village is about, adversary simulation, emulation and purple teaming, and why I started it: to give that community a place of its own at DEF CON. I used martial arts as an analogy for the idea behind the village, which I later wrote up on the blog: What is adversary simulation?
