An informal meetup of information security professionals in Chicago. Unlike other meetups, you will not be expected to pay dues, "join up", or present a zero-day exploit to attend.
Haymarket Pub, near downtown. Halsted & Randolph. Go grab someone and ask for "Chisec".
Here's a map
ChiSec is Wednesday, April 10th at 7PM. We stay until people get tired of hanging out. That seems to be about 3 hours.
It fills a gap. In other cities, there are regular professional meetups. Chicago has ISSA and 2621. We're less formal than ISSA. Nobody takes minutes. We just try to get to know the locals in our field.
