From Linux kernel livepatches to encryption to ASLR to compiler optimizations and configuration hardening, we strive to ensure that Ubuntu 16.04 LTS is the most secure Linux distribution out of the box.

The slides above try to briefly explain:

  • what we do to secure Ubuntu
  • how the underlying technology works
  • when the features took effect in Ubuntu

I hope you find this slide deck informative and useful!  The information herein is largely collected from the Ubuntu Security Features wiki page, where you can always find up to date information.
