Demystifying Android's Security Underpinings - Karim Yaghmour, Opersys

Android has relied from its early days on the Linux kernel for sandboxing the processes it runs. Yet, the permission model presented to app developers is significantly different from the Unix permission model. What's the relationship between those two models? How is Android's app security framework tied to the Linux kernel's security model? More recently, Android has started using SELinux and has been extended by SEAndroid to support similar functionality. How is SELinux used by Android and what is SEAndroid about? Furtheremore, how does Android provide support for multiple users?
