Apple designed the iOS platform with security at its core. When we set out to create the best possible mobile platform, we drew from decades of experience to build an entirely new architecture. We thought about the security hazards of the desktop environment, and established a new approach to security in the design of iOS. We developed and incorporated innovative features that tighten mobile security and protect the entire system by default. As a result, iOS is a major leap forward in security for mobile devices.
This document provides details about how security technology and features areimplemented within the iOS platform. It will also help organizations combine iOSplatform security technology and features with their own policies and procedures to meet their specific security needs.
Some light reading over the weekend.
But not sure how well publicized. It seems the secure enclave runs a “customized version of the L4 microkernel”.
Microkernel may represent an interesting approach to lessening the impact of Spectre and Meltdown: https://sourceforge.net/p/genode/mailman/message/36178974/
