This talk covers a distributed Wireless Intrusion Detection System using multiple Raspberry Pi boards. While there are more polished solutions on there, this solution works as a good proof of concept, or in house solution for small to medium businesses. This talk covers why scanning is needed, cost comparisons, a quick overview of setting up the Raspberry Pi, and the problems I've seen and had to adjust for since the original Proof of Concept. With luck and time permitting, we'll have a small version set up in the room, and we can show how the system works in real time.
