Someone without the password but with permission to modify the file will be capable of corrupting it (which would prevent you from accessing every protected file), but unless they somehow got access to the password they wouldn’t be able to view or modify the protected files.
Is it possible to force a corruption if a disk clone is attempted?
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
- I had a folder called
~/some/folder
. - It was on an encrypted drive.
- And I had done additional work to encrypt the folder again.
- And say, I used
chattr
,chmod
orchown
or similar utilities that remove access as long as one doesn’t have elevated privileges. - And say, I had done whatever (additional thing) mentioned in your comment.
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.
If you could be a bit more specific about your threat model people may have better ideas to help.
Threat model is me protecting myself from myself.
Incoming XY problem.
I want to prevent myself from reinstalling my system. The trick I came up with involved the use of files that couldn’t be disk cloned. However, if it’s far far easier to accomplish it through other means, then please feel free to enlighten me on this.
