Apple Platform Security, May 2022

[David Brooks]

Introduction to Apple platform security

Apple designs security into the core of its platforms. Building on the
experience of creating the world’s most advanced mobile operating
system, Apple has created security architectures that address the unique
requirements of mobile, watch, desktop, and home.

Every Apple device combines hardware, software, and services designed to
work together for maximum security and a transparent user experience in
service of the ultimate goal of keeping personal information safe. For
example, Apple-designed silicon and security hardware powers critical
security features. And software protections work to keep the operating
system and third-party apps protected. Finally, services provide a
mechanism for secure and timely software updates, power a protected app
ecosystem, and facilitate secure communications and payments. As a
result, Apple devices protect not only the device and its data but the
entire ecosystem, including everything users do locally, on networks,
and with key internet services.
