Most companies I’ve worked at where employees had a Microsoft work computers. They were under heavy control, even with admin privileges. I was wondering, for a corporate environment, how employees’Linux desktops could be kept under control in a similar way. What would be an open source or Linux based alternative to the following:
- policy control
- Software Center with software allow lists
- controlled OS updates
- zscaler
- software detection tool to detect what’s been installed and determine if any unallowed software is present
- antivirus
- VPN
I can think of a few things, like a company having it’s own software repos, or using an atomic distribution. There’s already open source VPN solutions if course. But for everything else I don’t really know what could be used or what setup we could have.

To get rid of Viruses, simply clean out all executable attachments in mails, mailcow and other solutions support that.
You can also mount /home nonexecutable, which means everything you can run needs to be on the system. Without that, “control over what is installed” is worthless. You could literally download any package, export the binary and run it from anywhere.
To run untrusted software, you can use a server that uses something like KASM. It is image-based, accessed through the browser, suppports uploading files and viewing lots of stuff. You can also run antivirus there, but as shown in this video antivirus is often simply tricked by encoding and re-encoding the scripts into something like Base64.
Antivirus really is flawed. You need to control the origins of code, and run all untrusted code in immutable VMs.

The correct way to call bash scripts is through bash, e.g.
bash badware.shExcel sheets can be used without macros, i.e. executable code. Macros can be disabled in Libreoffice afaik, and this is likely possible via some sort of policy.
These are great things to try out and I want to experiment with it when I have time. For example not sure if policies work with flatpak, as users could be able to change them.
Antivirus is a joke, for sure you could run it, but it just doesnt work. It would be just there for the compliance, while you simply dont run any code, not even trusted code, that doesnt come from trusted repos like Fedora, Ubuntu or flathub-verified
You know, it only now occurs to me that - in 20 years of setting up fairly complicated spreadsheets (for everything from finance to asset management) - I’ve never used a macro.
I honestly don’t know why you would, since per-cell functions update automatically. I certainly can’t imagine why it would need to make system calls. Whole thing seems like a massive security issue with no benefit.
