You know what happened at Google after Operation Aurora and they went full bore on security (BeyondCorp and all that)? They started phasing out Windows laptops for employees immediately.

I'm honestly having trouble taking you seriously, Windows has always been at the butt of security jokes, I guess you maybe didn't grow up with winnuke etc? But maybe you could elaborate a bit more concretely about what kind of intra-host security boundaries are missing, and why they would be required on single-user computers in this scenario?

I worked at Google on post-Aurora endpoints security. Windows laptops are alive and well at Google. Linux laptops have had one foot in the grave for a while now (it's a bummer). Google historically made gLinux work only with enormous investments in customised distros and D&R.

> But maybe you could elaborate a bit more concretely about what kind of intra-host security boundaries are missing

- no boundaries between applications, everything runs as $USER which can read your browser creds

- no boundary between user and root, everything can trivially escalate privs (maybe we will fix this post Glasswing, let's see)

- no boundary between boots, root can trivially persist a compromise (probably non-root too)

The tech exists to solve all these problems on Linux, but there isn't a distro that strings it all together. (Unless you count ChromeOS/Android which are not really OSS).

Wouldn't ChromiumOS and AOSP count? Though I read a lot of people generally complaining about secure boot on desktop (for reasons I honestly don't understand: secure boot seems to be part of the Android security model, and it seems valuable to me).

It's a good technical artifact yeah but it would need to be forked and degoogled, today it is only really useful with Google services as a backend.

Also it's coupled to the device ecosystem which is organised by Google. This coupling with the HW is one of its major technical strengths though, including for the security things I'm yapping about.

So yeah I think the two options for a EuroOS are:

- Fork and degoogle ChromiumOS/AOSP

- Invest in a Silverblue/bootc/Flatpak style system and just keep filling the gaps there

Hard to say which would be the better option. Both require at least tens of millions in investment over 5+ years.

D&R == detection and response

>why they would be required on single-user computers in this scenario?

Because the single user does not write all the software running on the system. The proprietary software the user downloads could have its own agenda contrary to the user. The open-source software has security holes so that for example if the OSS is being used to inspect a repo downloaded from the net, the repo might contain files specially crafted to exploit the open-source inspection software. Of if the OSS is a file viewer, a file downloaded from the net might be able to exploit the file viewer.
