Does the work I do with a Live USB Drive or Live DVD leave any trail (eg: tmp files) on my machine?

1

I want to know how Live DVD and USB drive work.

  • Do they use the disk of my PC at all?
  • If so, do they delete everything after I shut down the PC?
  • If so, are the tmp files deleted securely? Or they can be recovered?

I'm thinking of a Live DVD like BackTrack, which is used for security tests, etc.

They usually mount tmpfs to /tmp, which is an in-memory filesystem (like a ramdisk on steroids). So, it is as secure as your memory is.

1Might want to check that your live CD isn't automatically mounting any Swap partitions or a persistence files (called "casper-rw" on Ubuntu) though. – gmatht – 2016-08-13T03:10:59.403
