All presentations at CAC are speeches followed by question and answer sessions.
I held one on Blackhat a year or two ago and I didn’t get very far beyond definitions and examples, once you are talking time is a lot shorter than you may think .
I was bombed with questions about how it hurts us, how to find out whether we are being hurt and what to do about it for many months afterward.
That is why I suggest it, people are not interested in theory but in how they are affected and how to protect themselves, practical advice for their lives.
