Release Notes
For more information about this release, please see:

Security Onion 14.04 EOL Reminder
As a reminder, all new development is now on Security Onion 16.04 and Security Onion 14.04 will reach EOL on November 30, 2018:

After that date, we will not provide any support for Security Onion 14.04.  Please plan to upgrade or replace any existing 14.04 systems before that date.

Installation Guide
We've updated the Installation guide to reflect the download locations for the new ISO image:

Existing Deployments
If you have existing 16.04 installations, there is no need to download the new ISO image.  You can simply continue using our standard update process to install updated packages as they are made available:

If you have existing installations of Security Onion 14.04, you can upgrade from 14.04 to 16.04:

Thanks to Wes Lambert for testing this new ISO image!

Our next public 4-day Basic Course will be in San Antonio in February 2019!  We also offer private classes and online training!  For more information, please see:
