(since the underlying OS has no clue what permissions are) your only hope really is to only boot securable OSes, for the windows side use NT or W2K and not 9x or ME, and be sure to configure it to be secure (don't login to users in the administrators group, fix the broken filesystem permissions etc) > You're not paranoid.
