(More) Specifics:
- Undoing the protection should include filling in a password.
- The password should be different from the one used with
sudo
or any other passwords that are used for acquiring elevated privileges.
All (possible) solutions and suggestions are welcome! Thanks in advance!
Edit: Perhaps additional specifications:
- With 'displace‘, I mean anything involving that resembles the result of
mv
,cp
(move, cut, copy) or whatsoever. The files should remain in their previously assigned locations/places and should not be able to ‘pop up’ anywhere. - I require for the files to be unreadable.
- I don’t care if it’s modifiable or not.
- I don’t require this for my whole system! Only for a specific set of files.
I’ll straight up pose the question I asked someone else:
It seems I wasn’t clear as most people misunderstood me.
But, to give a very precise example; say
~/some/folder
.chattr
,chmod
orchown
or similar utilities that remove access as long as one doesn’t have elevated privileges.Then, what prevents whosoever, to copy that file through cloning the complete disk?
Even if they’re not able to get past the password, it will be found on the cloned disk. SO, basically, I ask for some method that prevents the file to even be copied through a disk clone. I don’t care that it has three passwords protecting it. What I want is for the disk clone (or whatever sophisticated copy/mv/cut or whatsoever utility exists) to somehow fail while trying to attempt the action on the protected files.
Nothing can stop anyone anywhere from cloning a storage device. You can encrypt it however many times you want, but it can still be read at the block level.
I’m not sure where the paranoia lands or is focused towards, but there is no storage device that exists that can’t be copied, so if that’s your hangup, you should just accept that and move on. If someone has physical access to your drives, then can copy it, but whether they can decrypt it is up for debate.
As the saying goes: given enough time and effort, anything can be brute-forced.
Clear. Thank you!
