We recently released the first Beta version of Security Onion 2.4:
https://blog.securityonion.net/2023/03/security-onion-24-beta-release-now.html

Today, we are excited to release the second Beta version of Security Onion 2.4!

Release Notes

Please review the Release Notes for changes in this release:
https://docs.securityonion.net/en/2.4/release-notes.html#beta-2-20230424-changes

Known Issues

Here are some known issues that should be resolved in later releases:

  • You cannot do an in-place upgrade from 2.3 to 2.4. We are still investigating data migration.
  • You must perform a new installation of Rocky Linux 9 Minimal and have full Internet access. We hope to have a 2.4 ISO image in a future release.
  • Upgrades from this 2.4 Beta release to anything else will not be supported. Starting in RC2 we will support soup to upgrade 2.4 grids.
  • Airgap mode is not supported at this time. This is due to a 3rd party dependency but will be supported in RC1. 
  • Ubuntu 20.04 support is not available until RC1. This has to do with a 3rd party dependency. 
  • ATT&CK Navigator doesn’t work correctly yet.
  • so-import-evtx imports logs but they don't get parsed correctly.
  • The following installation modes are NOT supported at this time:
    • Heavy Node
    • Receiver Node
    • Analyst Workstation

Transition from 2.3 to 2.4

When we release the final version of Security Onion 2.4, we will announce an End Of Life (EOL) date for Security Onion 2.3. Security Onion 2.3 will continue to receive security patches and priority bug fixes until it reaches EOL.

Warnings and Disclaimers

  • Beta software is not officially supported for production usage.
  • Ask your doctor if Beta software is right for you.
  • Using Beta software can cause a disruption in the space time continuum.

Enough warnings and disclaimers? Let’s go!

Installation

Our Security Onion 2.4 ISO image is not quite ready yet so for now you'll need to download Rocky Linux 9 Minimal:
https://download.rockylinux.org/pub/rocky/9/isos/x86_64/Rocky-9.1-x86_64-minimal.iso

Then check the checksum:
https://download.rockylinux.org/pub/rocky/9/isos/x86_64/CHECKSUM

Next, install Rocky Linux 9 and start our Security Onion installation as shown here:
https://docs.securityonion.net/en/2.4/installation.html#installation-on-rocky-linux-or-ubuntu

Once you've installed Rocky Linux 9 Minimal and started our Setup wizard, we highly recommend that you start with a simple IMPORT installation as shown here:
https://docs.securityonion.net/en/2.4/first-time-users.html

Once you have verified proper IMPORT installation, you can then try EVAL, STANDALONE, and DISTRIBUTED deployments as described here:
https://docs.securityonion.net/en/2.4/configuration.html
