Scouting report
Wrote Snort in 1998 as a lightweight packet sniffer, and it became the intrusion detection system that put IDS within reach of organisations that could never have bought one. Founded Sourcefire around it, which Cisco acquired in 2013. The Snort rule syntax outlived the product and is still how a large part of the industry writes network detections.
Curator’s note
A weekend tool that became the de facto standard for network detection.
