The discussion centers around Apple's innovative use of exclaves in their system on chips (SoCs) to enhance security through hardware-based virtualization techniques, particularly utilizing ARM's TrustZone technology. There is a significant emphasis on the hardware support for nested virtualization and how this could potentially mitigate security vulnerabilities. The community is eager for updates in Apple's Platform Security guide to understand better how these features are implemented. There is also a comparison made to Google's pKVM implementation on Pixel devices, highlighting a competitive landscape in hardware-driven security features across major tech players. The development of exclaves appears to be a defensive measure that sets Apple apart from other end-user device manufacturers, addressing concerns over system priviledge escalation and closer integration of security measures within the hardware design.
