Apple Announces ‘Memory Integrity Enforcement’

Apple Security Engineering and Architecture (SEAR):

Memory Integrity Enforcement (MIE) is the culmination of an unprecedented design and engineering effort, spanning half a decade, that combines the unique strengths of Apple silicon hardware with our advanced operating system security to provide industry-first, always-on memory safety protection across our devices — without compromising our best-in-class device performance. We believe Memory Integrity Enforcement represents the most significant upgrade to memory safety in the history of consumer operating systems.

That is, to say the least, an incredibly bold statement. But I think it’s true. This is a fascinating post, cogently written.
