Security Onion 2.3.50 Hotfix available!

Security Onion Solutions recently announced the release of Security Onion 2.3.50 which brings a ton of great fixes and features to the community. There have been many occasions where we have wanted to deploy small updates to Security Onion 2 but due to how the platform is built this was difficult to do… until now! Today we are announcing the introduction of hotfixes in Security Onion 2. This hotfix (GRIDFIX) addresses the following issues: 

  • Mixed or capital cased grid members will show up properly in the Grid view.
  • SOC will need to be restarted to remove the duplicate entries - so-soc-restart.
  • Raid status for Security Onion Solutions appliances should now properly update.

For those of you who have grids with capabilities to connect to the Internet for updates you can simply run “soup” on the manager and it will automatically apply the latest hotfix. Hotfixes will typically include updates to the salt code and small configuration changes that we want to get out to you without having to do a full release update. Any changes to docker containers will follow our normal release process and the version number will change. You will notice that the version numbers after a hotfix has been applied stays the same. The application of the hotfix is tracked on the manager in the /etc/sohotfix file. For more information, please see our soup documentation:
https://securityonion.net/docs/soup

If you are an airgap user we want you to know we have not forgotten about you. You too will be able to apply hotfixes starting in Security Onion 2.3.60. Users will see a couple of new commands for applying hotfixes. The first command so-airgap-hotfixdownload will be run from a computer with Internet access. This will download the hotfix and drop it into a tarball that you will then need to sneakernet over to your airgapped manager. Once you have copied that sohotfix.tar to a location on the manager you will run so-airgap-hotfixapply /path/to/sohotfix.tar and it will apply the hotfix. For more information, please see our airgap documentation:
https://securityonion.net/docs/airgap

We hope you are as excited as we are for this new functionality and look forward to continuing to bring cool and innovative features to the Security Onion Platform.
