Microsoft looking to restrict kernel level access after CrowdStrike incident might help us with our current Anti-Cheat dilemma (www.theverge.com)

CrowdStrike’s Falcon software uses a special driver that allows it to run at a lower level than most apps so it can detect threats across a Windows system. Microsoft tried to restrict third parties from accessing the kernel in Windows Vista in 2006 but was met with pushback from cybersecurity vendors and EU regulators. However, Apple was able to lock down its macOS operating system in 2020 so that developers could no longer get access to the kernel.

Now, it looks like Microsoft wants to reopen the conversations around restricting kernel-level access inside Windows.

Please, get this garbage out of the kernel. If it isn't there to talk to hardware, third party code has no place in the kernel. The same shit that Crowdstrike did could easily happen with any of these useless anticheats.

In b4 msft creates a level between kernel and user level for this stuff to sit at. It will have read-only access to all of kernel memory, and will otherwise function the same, but when it crashes it won't take the OS down, just certain programs that rely on it.

What will they call it? "Observer" level? "Big Brother" level? "Overseer" level? Probably just something to do with "Verifying Trust/Integrity". Google will also want to quietly stick something for "Web Integrity" there.

Is it just me, or does this seem like a reasonable solution? Assuming it's technically feasible.

It's still giving third party software kernel level control over your device, so you're still giving up any possibility of privacy and probably leaving yourself wide open to a backdoor attack, but that has been normalized. So to the degree that what people accept as reasonable these days is unreasonable, yeah, that's why I think MSFT will try it.
