iPhone Security Model

The video tutorial explains the iOS security model, focusing on features like reduced attack surface, stripped down iOS, privilege separation, code signing, data execution prevention (DEP), address space layout randomization (ASLR), and sandboxing. These features collectively enhance the security of iOS devices by minimizing vulnerabilities, controlling application permissions, and preventing unauthorized code execution.

What is Data Execution Prevention (DEP) and how does it enhance security?

Describe how Address Space Layout Randomization (ASLR) contributes to iOS security.

What is the purpose of sandboxing in iOS applications?
