Europe built sovereign clouds to escape US control. Then forgot about the processors (www.theregister.com)

Intel ME and AMD PSP: The silicon layer nobody certifies

About cloud sovereignty and the often-ignored and unknown on-CPU management engine running below the OS and BIOS.

The article is quite long; it explains how CPUs run firmware that can include remote management over the network, and can be running even when the OS is not. They can be vulnerable to supply chain attacks and firmware replacements. Because it's on hardware, the firmware with open security vulnerabilities is often not updated.

Regarding cloud, the French SecNumCloud is a framework for cloud infrastructure security requirements. It doesn't cover these hardware attack vectors specifically but may mitigate risks through surrounding practices and isolation.

In conclusion, even a cloud provider that meets SecNumCloud must be asked whether and how they manage CPU management engine attack vectors.

Good luck in trying to make a non-AMD or non-Intel x86 CPU. Maybe the chinese will find success in 10 years.

I dunno man, ARM and RISC-V are pretty dope.

It'd be nice if, say, ST would shit out a EU market RISC-V linux SoC akin to the CV1800B or SG2002 or BL808. But like, europe fabs.

Does Europe have fabs? Or are they purely reliant on Asia and the US fabs?

Would need a ton of investment but at least ASML is also a European company.
