I'm currently working on building the next version of the Security Onion LiveCD. It will be based on a fully-updated Xubuntu 10.04 and will have all the tools that were in previous versions with one exception: Snort 3.0 (SnortSP) currently does not compile on Ubuntu 10.04. However, the new Suricata IDS/IPS engine does compile so it will be taking the place of SnortSP. You'll be able to choose between the current production version of Snort (2.8.6.1) or Suricata. Regardless of which IDS engine you choose, your alerts will be available for analysis in Sguil.
We've been nearing the limit of a 700MB CD image for some time, so we will be switching to a DVD image to allow for more software. What suggestions do you have for the new version of the Security Onion LiveCD? Please leave a comment here or add your suggestion at the
Security Onion Issue Tracker. Thanks!
