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.

Security Onion 2.3.40 now available!

Last October, we released Security Onion 2.3:
https://blog.securityonion.net/2020/10/security-onion-2-has-reached-general.html

Today, we are releasing Security Onion 2.3.40, which adds new features and resolves a few issues:

https://docs.securityonion.net/en/2.3/release-notes.html#changes


Elastic 7.11.2

Elastic recently changed their licensing:
https://securityonion.net/elastic-license

Elastic 7.11.2 is available under the Elastic License. You will be prompted to accept the Elastic License for new installations or upgrades.

Accept the Elastic License

Our Elastic integration now uses Elastic Security for encryption. All Elastic communication will be encrypted with TLS/SSL. Enabling HTTPS encryption in Elastic automatically turns on Elastic authentication as well. To maintain the current functionality, we will enable anonymous access to Elasticsearch and Kibana. This anonymous access mimics the access controls of previous versions of Security Onion where access is controlled via the firewall for these services. If you are using any external services that are connecting directly to Elasticsearch on port 9200, then you will need to change those to use HTTPS when you upgrade to Security Onion 2.3.40.

You will also notice changes in Kibana. First, you will see several new menu options that come with the new Elastic License. You will also see in the upper right corner that you are logged in as the user "anonymous". In previous OSS versions of Kibana, you were logged in as anonymous by default, it just didn't display the user in the upper right corner.

Documentation

We've started migrating our documentation to 2.3:

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

AWS Marketplace

For new Security Onion 2 installations, version 2.3.40 is now also available on AWS Marketplace via the official Security Onion 2 AMI:
https://securityonion.net/aws/?ref=_ptnr_soc_blog_210323

UPDATE 2021/03/23 2:06 PM Eastern
We've identified an issue with the 2.3.40 AMI that would prevent ssh access after reboot and so we have requested removal from the AWS Marketplace. This issue only affects the AWS AMI and should not affect any other installation method. You can use the 2.3.30 AMI and update via soup.

AMI Documentation:
https://securityonion.net/docs/cloud-ami

Existing Security Onion 2 AMI users should use the "soup" command to upgrade.

Security Onion 16.04 EOL

Ubuntu 16.04 reaches EOL in April 2021 and so therefore Security Onion 16.04 does as well. Please make plans to replace or upgrade any existing Security Onion 16.04 deployments before then:
