As I've mentioned a few times before, this year I'm working on getting my OT security chops up to speed, and that means getting a lot more familiar with the way SCADA and ICS systems work when they're functioning properly, to better appreciate how they can be exploited when reached by those with impure thoughts and nefarious motives.

To that end I reach out to folks who seem to know more about this part of the world than I do (sadly, a group that must number in the hundreds of millions). I'm not always successful, but when I am, am happy to share my success so you can advance your own understanding, if necessar, as well.
