I have setup an Ubuntu Server for my university project. Aside from full disk encryption I also intend to use Dafturn Ofris (a Linux deepfreeze) to make file recovery difficult or for any forensics carried out.
Is there a way I could change system settings so that whenever any file is deleted shred is used? I am sure the OS often deletes files during its operations (such as temporary files), which along with the software I am running on my server (which shreds files) should hopefully make a complete mess for any adversaries.
I am sure this will slow down the server, however if I keep the iteration at 1 pass then hopefully the speed difference should not be too noticeable?
Thank you!
