Finally, this release also updates many components including:

  • Elastic 7.16.3
  • FleetDM 4.8.0
  • Grafana 8.3.2
  • Zeek 4.0.5
  • CyberChef 9.32.3
TheHive

In September 2021, StrangeBee announced a change to TheHive’s licensing model and ended support for TheHive version 3 effective December 31, 2021 (see https://medium.com/strangebee-announcements/faq-for-thehive-5s-upcoming-distribution-model-af0ccb95d18). The new licensing model for TheHive version 5 is not compatible with our project so we must say goodbye to TheHive. Starting in Security Onion 2.3.100, we are transitioning from TheHive to Cases. Existing installations with TheHive enabled will still be able to use TheHive and access their existing TheHive data for a very short time. However, new installations will not be able to enable TheHive. We will stop including TheHive container images starting in Security Onion 2.3.120, currently scheduled for release in March 2022. From that point forward, users running the current version of Security Onion will no longer be able to natively run TheHive on the platform and our support for TheHive on Security Onion will end. Users wishing to continue using TheHive on Security Onion should plan to migrate to an external instance of TheHive. For now, users will still be able to escalate events from Security Onion Console to external instances of TheHive version 3.

Documentation is always a work in progress and some documentation may be missing or incorrect. Please let us know if you notice any issues.

New Installations

If you want to perform a new installation, please review the documentation and then you can find instructions here:

Existing 2.3 Installations

If you have an existing Security Onion 2.3 installation, please be aware that custom settings in Kibana may be overwritten during upgrade. Also note that this version upgrades to salt 3004 and that process can be complicated. If possible, we recommend that you test the upgrade process on a test deployment before deploying to production. If you have a distributed deployment, then we recommend monitoring SOC Grid while your update is running to verify that all nodes update properly. If there are issues, you can review logs, services, and containers for any additional clues. If you need help, please see our support information below.

For more information about the update process, please see:
https://docs.securityonion.net/en/2.3/soup.html

About Security Onion

Security Onion is a versatile and scalable platform that can run on small virtual machines and can also scale up to the opposite end of the hardware spectrum to take advantage of extremely powerful server-class machines.  Security Onion can also scale horizontally, growing from a standalone single-machine deployment to a full distributed deployment with tens or hundreds of machines as dictated by your enterprise visibility needs.
