Not that specific, but security was definitely part of the process.
My advise: study any specific systems or technologies in the job posting... but otherwise, just relax and be yourself... If you're qualified, just be confident that you are. (But don't be a cocky jerk)
I used this technique on my first interview in >20 years... and I have an offer letter pending.
I just wasn't stressed, and looked at the whole 3- interview process as a way to get to know each other, not as a test. As it turned out, I liked what I saw and so did they.
And, Good luck!
