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.

Known Issues
Please be aware of the following known issue:

TheHive
As a reminder, 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 April 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.

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. 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.
