securityonion-setup - 20120912-0ubuntu0securityonion296 now available for Security Onion!

securityonion-setup - 20120912-0ubuntu0securityonion296 is now available and should resolve the following issues:

so-allow: add OSSEC/Wazuh registration service option #1506
https://github.com/Security-Onion-Solutions/security-onion/issues/1506

Setup: /etc/network/interfaces ethtool rx setting should be commented out by default #1508
https://github.com/Security-Onion-Solutions/security-onion/issues/1508

Discussion
Richard Bejtlich recently blogged about an issue with Virtualbox and /etc/network/interfaces:
https://taosecurity.blogspot.com/2019/04/troubleshooting-nsm-virtualization.html

We were able to duplicate the issue and determine that it had to do with the ethtool -G rx setting.  Traditionally, our Setup script has used ethtool -g to determine the maximum rx setting and then ethtool -G to enforce that maximum rx setting.  It seems as if VirtualBox 6.0.4 may have an issue whereby its virtual network interfaces report a maximum rx setting of 4096 but are unable to reliably be set to that value.  Therefore, the safest option for widest compatibility is to keep the rx setting at its default value.  Additionally, some folks are recommending lower rx values for better performance:
https://github.com/pevma/SEPTun/blob/master/SEPTun.rst

Our new Setup script continues to write the ethtool -G rx setting into /etc/network/interfaces but it is now commented out by default.  If you need to modify this, you can certainly do so.

For more information, please see the Network Configuration page on our Documentation site:
https://securityonion.readthedocs.io/en/latest/network-configuration.html

Thanks
Thanks to Richard Bejtlich for reporting the /etc/network/interfaces issue!

Security Onion Docker Images NOT Affected by Recent Docker Hub Data Exposure

In Security Onion 16.04, our Elastic components are delivered via Docker images stored on Docker Hub.  Docker recently announced unauthorized access to a single Docker Hub database:
https://success.docker.com/article/docker-hub-user-notification

From the article:
Q: How do I know if I was impacted by this unauthorized access?
If you directly received an email from Docker about this incident, you may have been impacted. If you have received a password reset link, your password hash was potentially exposed. We have invalidated it and sent you a password reset link as a precaution. If you are using autobuilds and your GitHub or Bitbucket repositories have been unlinked from Docker Hub, you will need to relink those repositories for autobuilds to work correctly.
Security Onion does NOT use autobuilds and did NOT receive an email from Docker, so we don't have any reason to believe that our Docker accounts or images were impacted.  However, to err on the side of caution, we have verified our Docker images and reset our passwords.  Finally, please note that our images are digitally signed using Docker Content Trust:
https://docs.docker.com/engine/security/trust/content_trust/
