12.10 orginally shipped with Nautilus 3.2 however I have found this somewhat buggy. I used this article to update Nautilus to 3.6. A small note, the odd number realeases like 3.5 are considered unstable so my advice would be to keep a even number release for the most compatability. Since the upgrade. Nautilus hasn't crashed. I have a 12.10 64 bit. I will leave the link for those who wish to look into it

Why SANS for Computer and Information Security Training?

As the leading organization in computer security training, the SANS Institute is known for providing intensive, immersion training designed to help you and your staff master the practical steps necessary for defending systems and networks.

We also develop, maintain, and make available at no cost the largest collection of information security research documents and whitepapers about various aspects of information security and operate the Internet's early warning system - the Internet Storm Center.

At the heart of SANS are the many security practitioners in government agencies, corporations, and universities around the world who invest hundreds of hours each year in research and teaching to help the entire information security community.
What makes SANS courses the best investment for information security training:

I'm going to start by saying that if you didn't make it to SCaLE this year you missed quite an event. Everything about this event was top notch. The Westin has the most comfortable beds in the world. I am qualified to make that statement if you need to know my qualifications, feel free to contact me by any means you have at your disposal. Oh, before I go any further, I want to thank Nate Hutchins (hutchnate) because if it hadn't been for his proactive nature I wouldn't have been able to go. Ya see, it was his idea in the first place and he drove.
