In this talk, two of the leading iOS experts will take you though the iOS security architecture. They will outline the way iOS protects itself from malware and exploitation, including memory protections, sandboxing, address randomization, privilege separation and code signing. They will walk through the attacks that have occurred against iOS since its inception as well as how the architecture withstood (or didn't) these attacks and why. In addition, the session will discuss how the security posture of iOS has changed over time.
