In about an hour, I have the distinct honor to address a room full of federal sector security researchers and scientists at the US Department of Energy's Oak Ridge National Labs, within the Cyber and Information Security Research Conference.
I'm delighted to share with you the slide deck I have prepared for this presentation. You can download a PDF here.
To a great extent, I have simply reformatted the excellent Ubuntu Security Features wiki page our esteemed Ubuntu Security Team maintains, into a format by which I can deliver as a presentation.
Hopefully you'll learn something! I certainly did, as I researched and built this presentation ;-)
On a related security note, it's probably worth mentioning that Canonical's IS team have updated all SSL services with patched OpenSSL from the Ubuntu security archive, and have restarted all relevant services (using Landscape, for the win), against the Heartbleed vulnerability. I will release an updated pollinate package in a few minutes, to ship the new public key for entropy.ubuntu.com.
