Security Onion 2.4.90 now available including improvements for Detections and much more!

Security Onion 2.4.90 is now available! 


Security Onion is a cybersecurity platform built by defenders for defenders. Recently, we released Security Onion 2.4.70 which was the culmination of several MONTHS of thinking through the defender workflow specifically around detection engineering. This resulted in a new interface called Detections that makes it super simple to tune your NIDS rules for Suricata, Sigma rules for ElastAlert, and YARA rules for Strelka. In 2.4.80, we listened to your feedback about Detections and made lots of improvements including syntax highlighting and much more. In this 2.4.90 release, we continued to iterate on Detections with regex support, massive performance increases, and history diff highlighting!


In addition to Detections improvements, we've also added a new action to the SOC Actions menu that makes it easier for you to add your own custom actions!


Clicking this new action will take you directly to the configuration screen for actions:


In that last screenshot, you'll notice a new icon in the upper right corner of the config section. Clicking this new icon will expand the config section to full width to make it easier to read and customize larger config settings.


There are many more features and fixes included in this release! For a complete list of all changes, please see the Release Notes:

About Security Onion


Security Onion is a free and open platform built by defenders for defenders. It includes network visibility, host visibility, intrusion detection honeypots, log management, and case management. 


For network visibility, we offer signature based detection via Suricata, rich protocol metadata and file extraction using your choice of either Zeek or Suricata, full packet capture, and file analysis. For host visibility, we offer the Elastic Agent which provides data collection, live queries via osquery, and centralized management using Elastic Fleet. Intrusion detection honeypots based on OpenCanary can be added to your deployment for even more enterprise visibility. All of these logs flow into Elasticsearch and we’ve built our own user interfaces for alerts, dashboards, threat hunting, case management, and grid management. 


Security Onion has been downloaded over 2 million times and is being used by security teams around the world to monitor and defend their enterprises. Our easy-to-use Setup wizard allows you to build a distributed grid for your enterprise in minutes!

New Installations


If this is your first time installing Security Onion 2.4, then we highly recommend starting with an IMPORT installation as shown at:


https://docs.securityonion.net/en/2.4/first-time-users.html


Once you’re comfortable with your IMPORT installation, then you can move on to more advanced installations as shown at:


https://docs.securityonion.net/en/2.4/architecture.html


Existing 2.4 Installations


If you have an existing Security Onion 2.4 installation, you can update to the latest version using soup:


https://docs.securityonion.net/en/2.4/soup.html


Before updating your production deployment, we highly recommend testing the upgrade process on a test deployment that closely matches your production deployment if possible.


If you haven't already upgraded to 2.4.70 then, in preparation for the new Detections module, the following will be completed during soup:

  • Playbook Plays will be backed up to /nsm/backup/detections-migration/ and any active Elastalert rules will be backed up and removed.
  • Suricata tuning configurations will be backed to /nsm/backup/detections-migration/ and any thresholds will be migrated over to the new Detections module.


2.3 EOL


As a reminder, Security Onion 2.3 reached End Of Life (EOL) on April 6, 2024:
