As a Home Assistant user, how do you ensure security? Most advice on the internet talks about the network.Make a VLAN.Enforce a firewall.
But the official sources tell a different story.One about what happens once something malicious is already running inside the hub.That's a problem you'd rather want to solve using Qubes OS.
Home Assistant trusts everything running on it, and that's the problem The flat permission model you should be aware of Too much flexibility isn't always nice.In fact, Home Assistant's own security documentation admits that every logged-in user is seen as fully trusted.That means there's no separation between accounts.
Now, if only every automation running in Home Assistant came from a single source, that wouldn't be a big issue.But the reality is different.A good number of things Home Assistant is useful for come from the Home Assistant Community Store (HACS) and custom integrations, code written by hobbyists.
These are not approved like core integrations.If you do some research, you'll find many security disclosures that Home Assistant has published regarding file theft using custom integrations without even logging in.Security audits, including a prominent code review by the GitHub Security Lab, have routinely uncovered serious vulnerabilities in the ecosystem.
Researchers have found everything from flaws that allow malicious links to silently trigger internal smart home actions, to critical path-traversal vulnerabilities in the backup system that allow an attacker to write files anywhere on the container's filesystem.The point is, the software you're integrating with the HA ecosystem deserves an extra wall of security to make it safer.Related I Found the Best Way to Install Home Assistant Sometimes, I forget I even have Home Assistant running because it's so reliable now.
Posts 18 By Patrick Campanale Qubes OS treats every piece of software like it's guilty until proven innocent A paradigm shift in how you deal with untrusted sources Here's the interesting part about Qubes OS.Instead of running one operating system, it runs several.Each is isolated from the other using the Xen hypervisor.
On top of that, there's a lightweight admin layer called dom0 tying everything together.Each of these isolated environments is a "qube." What's fascinating is that each qube can handle different tasks.One might handle your browsing while another handles something riskier.
What makes this even more ingenious is that not every qube has direct access to your hardware.There are dedicated networking qubes for routing traffic.So suppose you're running Home Assistant on one qube.
It only has access to what you give it.In case something is compromised, it won't affect the other qubes.Close This strict architecture introduces so many features that make Qubes safer and better than other Linux distros for Home Assistant.
You can test shady HACS integration in an isolated qube and completely wipe it later.You also have template-based qubes, which allow you to have isolated sections without a full OS installation each time.Moreover, you have control over what Home Assistant can talk to by configuring per-qube firewalls.
VLANs and Proxmox get you close, but not all the way there Where network isolation stops and app isolation begins A lot of Home Assistant guides push you toward setting up VLANs.That's commendable.If you can put your IoT devices on separate network segments, then a compromise on one section won't infect your whole network.
However, VLANs are only limited to the network layer.In other words, if there is something malicious inside Home Assistant itself, there's nothing you can potentially do with a VLAN.So what fix can you apply? Proxmox is one option.
A lot of people like to run Home Assistant inside Proxmox instead of spinning a Docker instance for it.It's pretty useful for virtualizing your homelab.However, consider this.
Proxmox is a phenomenal Type-1 hypervisor.Running Home Assistant inside a Proxmox VM isolates it perfectly from your other server applications.But it's built for headless server consolidation.
It expects your apps to live statically in a server closet.This is exactly where Qubes OS leaves it in the dust.Qubes isn't a server OS.
It’s a desktop operating system built around compartmentalization.It brings hypervisor-level security right to your desktop workflow, making the administration of a complex, untrusted smart home environment much less of a headache.Qubes OS is genuinely more work Home Assistant doesn't make it any easier either Now's the time to come out honestly.
This setup isn't everyone's cup of tea.If you ever scrolled through the Qubes or Home Assistant community forums, you'll find people who managed to get Home Assistant running fine inside a qube, but then hit a wall getting it to actually talk to the rest of their network.Qubes also requires good hardware.
You'll need IOMMU support and enough RAM to keep several qubes running without problems.USB passthrough for a Zigbee or Z-Wave dongle adds another step, which, unfortunately, a lot of homelabbers coming from simpler setups forget about.If you already have a working setup, you don't have to throw it away for this.
However, if it's something about Qubes OS that is holding you back from trying this out, it's worth knowing some of the myths about Qubes OS that scare people off before leaving it untouched.Related 6 self-hosted apps that are better with Proxmox The "just use Docker" crowd isn't going to like this one.Posts 2 By Umair Khurshid Your smart home deserves better walls Running Home Assistant on Qubes OS isn’t the easiest path, but it is undeniably a safer one.
If privacy and security are non-negotiable for you as a homelabber, you could give this setup a try without full commitment.If you think Qubes is not for you, then a dedicated Proxmox VM is still viable.
