Security Onion 12.04.4 ISO image now available

We have a new Security Onion 12.04.4 ISO image now available that contains all the latest Ubuntu and Security Onion updates as of February 21, 2014!

Changes since 12.04.3 ISO

The new 12.04.4 ISO image has all Ubuntu and Security Onion updates as of 2/21 including:

  • Linux kernel 3.2.0-59
  • Snort 2.9.5.6
  • Suricata 1.4.7
  • Bro 2.2
  • ELSA 1.5
  • Squert 1.2.0
  • CapMe
  • securityonion-web-page (ELSA query page at https://onion/elsa)
  • Setup
  • sostat
  • NSM scripts
  • ET ruleset (/etc/nsm/rules/downloaded.rules)

Changes in the ISO Image Itself

The new 12.04.4 ISO image resolves a few issues in the ISO image itself:

  • boot menu: the Install option never really worked right and has now been removed so that folks will choose one of the Live options that allow them to Install but also allow them to check hardware and read the README
  • boot menu: added "nomodeset" option since some folks needed that to boot on certain video chipsets
  • after choosing an option on the boot menu, the Xubuntu boot progress indicator has been replaced with a Security Onion boot progress indicator
  • unnecessary shortcuts have been removed from the Live desktop so that users don't try to run Setup before running the Installer
  • previously, if you ran "sudo service nsm status" before running Setup, you'd get an error message.  This has been resolved.
  • salt-master and salt-minion were previously enabled on ISO boot, which resulted in lots of DNS lookups for "salt".  They are now disabled by default (you can still enable them during Setup of course).
  • byobu is now included by default:
    https://help.ubuntu.com/community/Byobu

In short, it's the best release ever!

Existing Deployments
If you have existing installations based on our original 12.04 ISO image, there is no need to download the new 12.04.4 ISO image.  You can simply continue using our standard update process to install updated packages as they are made available:

Release Notes

  • When you update the package, it will copy new files into place and then display "Updating database".  Please do not cancel or interrupt this process.
  • You no longer have to hardcode your Sguil credentials in config.php.
  • You may need to Shift-Reload in your browser and/or empty browser cache to ensure you're running the latest Squert javascript.
  • Timestamps are displayed in UTC by default, but you can change this by clicking the arrows to the right of the timeline.  De-select UTC, then specify your local timezone offset.  Then click the "save TZ" button to save your preference into the database and click "Update" to refresh the page with the new timestamps.

New securityonion-elsa-extras package properly randomizes apikey on master server

Scott Runnels has updated the securityonion-elsa-extras package to properly randomize the ELSA apikey on the master server.  Thanks, Scott!

The updated package version is securityonion-elsa-extras - 20131117-1ubuntu0securityonion36 and it has been tested by the following (thanks!):
Michal Purzynski
David Zawdie

Issues Resolved
Issue 478: securityonion-elsa-extras: randomize API key in master's elsa_web.conf
https://code.google.com/p/security-onion/issues/detail?id=478

Release Notes
When the new package installs, it will check /etc/elsa_web.conf to see if you have an apikey set to the default of "1".  If so, it will automatically replace that default apikey with a properly randomized apikey.  You'll then need to restart Apache to make the change take effect:
sudo service apache2 restart

Please be reminded that the management interface of your master server (where the ELSA web interface runs) should be connected to a dedicated management network or locked down via firewall rules to only accept connections from analyst IP addresses:
https://code.google.com/p/security-onion/wiki/Firewall
