Azure Sphere: Fitting Linux Security in 4 MiB of RAM – Ryan Fairfax, Microsoft
Azure Sphere: Fitting Linux Security in 4 MiB of RAM – Ryan Fairfax, Microsoft
Azure Sphere is a new solution for building highly secured, connected microcontroller-powered devices. It includes a customized version of the Linux kernel and work to fit the OS within a highly constrained memory footprint. In this talk we will cover the security components of the system, including a custom Linux Security Module, modifications and extensions to existing kernel components, and user space components that form the security backbone of the OS. Along the way we’ll discuss false starts, failed attempts, and the challenges of taking modern security techniques and fitting them in resource constrained devices.
