Apple Secretly Bolsters iOS and macOS Security with 'Exclaves'

Apple is secretly developing a security feature called "exclaves" within its XNU kernel to enhance the security of iOS and macOS. This technology, resembling a microkernel approach, isolates critical functions, protecting the system even if the kernel is compromised. Leveraging new architecture and the Secure Page Table Monitor hardware security, sensitive services are compartmentalized, preventing a single vulnerability from compromising the entire kernel address space. This enhances security for growing on-device AI workloads and cloud interactions.
