Device security with the Arm platform security Architecture

Course Convenor: Trevor Martin

Course Duration: 2 day

Course Overview


In this one-day course, we will introduce the skills and techniques required to defend your IoT devices against software attacks. This course starts by demonstrating the potential risks and how attackers can seize control of devices and systems. We'll delve into the world of Threat Modelling, a crucial technique for identifying and countering possible attack vectors.

Our focus then shifts to the PSA Security Model, a cornerstone in IoT device security. A highlight of this model is its system partitioning approach, a method that distinctly separates application firmware from secure services and data. You'll gain an in-depth understanding of how this is accomplished using Arm TrustZone for Cortex-M, paired with the practical application of the CMSIS Zone Utility for configuring complex memory maps.

Diving deeper, we'll explore the architecture of the Arm PSA Trusted Firmware for Cortex-M software, learning how to leverage its security services, including cryptography, secure storage, event logging, and attestation. Understanding the necessity of firmware updates in any IoT system, we'll examine the integration of the mcuBoot bootloader in the TF-M firmware, guiding you through the process of preparing and signing update images.

Join us in this comprehensive course to master the art of securing IoT devices, where practical knowledge meets theoretical foundations, setting the stage for a future-proofed understanding of IoT security.
