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:
