Security Onion 2.1 (Release Candidate 2) Available for Testing!

In 2018, Security Onion Solutions started working on the next major version of Security Onion, code-named Hybrid Hunter:

We recently dropped the Hybrid Hunter code name and announced 2.0 (RC1).  Today, we are proud to release Security Onion 2.1 (Release Candidate 2)! It has some amazing new features and improvements!

One new feature in this release is that the installer now includes a new option for a dedicated import node. An import node is a single standalone box that runs just enough components to be able to import a pcap using so-import-pcap. When you run so-import-pcap, it analyzes the pcap using Suricata and Zeek and the resulting logs are picked up by Filebeat and sent to Elasticsearch where they are parsed and indexed. You can then view those logs in Security Onion Console (SOC). All this can be done in a minimal virtual machine with only 4GB RAM! For screenshots of the new import node, see the Screenshot Tour at the bottom of this blog post.

Another new feature that you'll see in the Screenshot Tour is that our new Hunt interface is better than ever! It now dynamically updates the columns in the bottom data table based on the actual data type that you're looking at. For example, if you're looking at DNS logs, Hunt will show columns that are relevant to DNS logs like the DNS query, type, and response code.  Additionally, you'll notice that where field values used to have two magnifying glass icons (one to include the value in the search and the other to exclude the value from the search), there is now a third magnifying glass icon. This new icon starts a new search for just the value itself.

Release Candidate

This is our second Release Candidate for the new 2.x platform, so we're getting closer to a final release, but we're not quite there yet. Please be reminded of the usual pre-release warnings and disclaimers:

  • If this breaks your system, you get to keep both pieces!
  • This is a work in progress and is in constant flux.
  • This configuration may change drastically over time leading up to the final release.
  • Do NOT run this on a system that you care about!
  • Do NOT run this on a system that has data that you care about!
  • This script should only be run on a TEST box with TEST data!
  • Use of this script may result in nausea, vomiting, or a burning sensation.


We've started migrating our documentation to 2.1:
