Suricata — barnyard2/sguil-sensor — snortsam — cisco route
The Open Information Security Foundation (OISF) will provide support to Ian Firns (aka “firnsy”), one of the official Barnyard2 maintainers at SecurixLive, to help get a few milestones completed within the Barnyard2 roadmap. Most significantly a Snortsam Output Plugin will be completed to allow both Snort and Suricata users to more easily plug in to Snortsam for distributed blocking and response using Frank Knobbe’s Snortsam project. This will make using Snortsam much easier as it will no longer require patching Snort or Suricata on each upgrade.
Barnyard is a critical piece of Suricata as well as Snort, so this support is beneficial to the community as a whole!
