Research: HPI Finds Apple Is Reworking iOS Security Architecture
Research: HPI Finds Apple Is Reworking iOS Security Architecture New research from Moritz Steffin and Jiska Classen at the Hasso‑Plattner‑Institut (University of Potsdam) provides the first deep look into modern iOS security mechanisms. Their analysis shows Apple has significantly changed iOS's internal architecture, introducing separated security domains and other structural changes intended to raise the bar for attackers. The paper highlights several key shifts in iOS design: Segmentation of security domains to limit the blast radius of compromises. Changes to process isolation and privilege boundaries within the OS. New or reworked central components that enforce security policies more strictly. These architectural moves suggest Apple is evolving iOS beyond incremental hardening toward a more structural approach to security. That can make exploitation harder for attackers, but may also change how researchers…
