QuickISOImage

If you just want to quickly evaluate Security Onion using our ISO image (based on Xubuntu 12.04 64-bit):

1. First, review the Hardware Requirements page.
2. Download the ISO image from Sourceforge or via Torrent.
3. Once the ISO image download has completed, verify the checksums as shown here: http://blog.securityonion.net/2015/09/security-onion-120453-iso-image-now.html
4. Boot the ISO image into the Live Desktop environment and then double-click the Install icon on the desktop.
5. Follow the prompts in the Xubuntu installer. If prompted with an encrypt home folder option, DO NOT enable this feature. If asked about automatic updates, DO NOT enable automatic updates. Reboot into your new installation. Login using the username/password you specified during installation.
6. Verify that you have Internet connectivity. If necessary, configure your proxy settings.
7. Install updates and reboot.
8. Double-click the Setup icon. The Setup wizard will walk you through configuring /etc/network/interfaces and will then reboot.
9. After rebooting, log back in and start the Setup wizard again. It will detect that you have already configured /etc/network/interfaces and will walk you through the rest of the configuration.
10. Once you've completed the Setup wizard, use the Desktop icons to login to Sguil, Squert, Snorby or ELSA.
11. Finally, review the Post Installation page.
