Docker as an alternative to Qubes OS?

Question

Information Security

Hey!
There is QubesOS designed to secure work with software by isolating processes from each other. May I prefer to use Docker instead of the whole OS? Naturally, we are talking about software without a GUI, because the graphical shell should also be isolated . The
question concerns the security of this preference. The cubes itself, as far as I know, is very unstable, and, in my opinion, is quite redundant in some moments.

Answer 1

Nothing is isolated there. This is conditional isolation and overhead. All this is in the Linux kernel. Docker is just an add-on, just like LXD.
