Tools 04 – Operating System Hardening

Your Challenge

  • Investigate hardening of operating systems.
  • Choose Linux, Windows or you could look in both. We would rather some depth than breadth here so only choose both if you choose to go deep on both.
  • Note that you could choose a different OS if you like (say FreeBSD)
  • You should actually implement some/most of this in your own installation. Perhaps use a virtual machine for that.
  • Document on your blog and use the hashtag #tools04
