Building Secure Devices on the Intelligent Edge with Azure Sphere

Building secure devices on the intelligent edge with Azure Sphere Paul Foster, Microsoft Dr Hassan Harb, E.On Microcontrollers (MCUs) low-cost, single chip computers 9 BILLION new MCU devices built and deployed every year Radio 2.4GHz WiFi MCU 192Mhz Cortex-M4 256KB SRAM 1MB NOR FLASH GPIO, I2C, I2S, etc. RTOS (no kernel) Connected devices create profoundly better customer experiences. How does a consumer know the compressor in their fridge needs to be replaced? Option 1 Option 2 Melted ice cream Predictive maintenance Mirai Botnet attack Everyday devices are used to launch an attack that takes down the internet for a day SECURITY IS FOUNDATIONAL It must be built in from the beginning. The 7 properties of highly secured devices Hardware Defense Small Trusted Root of Trust in Depth Computing Base Dynamic Certificate-Based Failure Renewable Compartments Authentication Reporting Security Some properties depend only on hardware support Hardware Root of Trust Hardware Root of Trust Unforgeable cryptographic keys generated and protected by hardware • Hardware to protect Device Identity • Hardware to Secure Boot • Hardware to attest System Integrity Some properties depend on hardware and software Defense in Dynamic Small Trusted Depth Compartments Computing Base Dynamic Compartments Internal barriers limit the reach of any single failure • Hardware to Create Barriers • Software to Create Compartments Some properties depend on hardware, software and cloud Certificate-Based Failure Renewable Authentication Reporting Security Renewable Security Device security renewed to overcome evolving threats • Cloud to Provide Updates • Software to Apply Updates • Hardware to Prevent Rollbacks Azure Sphere is an end-to-end solution for securing MCU powered devices The Azure Sphere OS with ongoing updates creates a Microsoft-secured software platform Azure Sphere certified MCUs, from our silicon partners, with built-in Microsoft hardware root of trust. The Azure Sphere Security Service guards every Azure Sphere device. It brokers trust, detects emerging threats, and renews device security. Azure Sphere certified MCUs create a secured root of trust for connected, intelligence edge devices C O N N E C T E D with built-in networking Microsoft Network Pluton FLASH Connection Security ≥ 4MB WiFi in first chips SECURED with built-in Microsoft silicon Subsystem security technology including the Pluton Security Subsystem Firewall Firewall Firewall ARM ARM CROSSOVER Cortex-A processing power Cortex-A SRAM Cortex-M optimized for ≥ 4MB for real time brought to MCUs for the first time low power processing CROSSOVER Cortex-A processing power Firewall Firewall Firewall brought to MCUs for the first time Multiplexed I/O GPIO PWM TDM I2S UART I2C SPI ADC Azure Sphere MCUs create a secured root of trust for connected, intelligence edge devices Pluton features implemented in silicon include A hardware root of trust that -accelerates common cryptographic operations (ECC and AES) -generates public/private keypairs -implements secure boot (via ECDSA) A dedicated core and memory (TCM) that -resists side-channel attacks that focus on a single core A true random number generator that -defends against low-entropy attacks Measured boot and remote attestation that -uses a digest accumulator register and nonce register Our Silicon Partners The Azure Sphere OS is optimized for IoT, security, and agility Azure Sphere OS Architecture Secure Application Containers Compartmentalize code for agility, robustness & security OS App Containers for App Containers for Layer 4 POSIX (on Cortex-A) I/O (on Cortex-Ms) On-chip Cloud Services Provide update, authentication, and connectivity OS On-chip Cloud Services Layer 3 Custom Linux kernel Empowers agile silicon evolution and reuse of code OS HLOS Kernel Layer 2 Security Monitor Guards integrity and access to critical resources OS Security Monitor Layer 1 Hardware Azure Sphere MCUs Application platform • Cortex-A • App runs in Normal World user mode • GPIO, UART and other interfaces • Communicate with Azure IoT Hub or other clouds • Microsoft provides all but app SIDE BAR SIDE • All signed by the Microsoft CA • App updates delivered by Microsoft secure pipeline • Sideloading during development • Manifest file defines capabilities The Azure Sphere Security Service connects and protects every Azure Sphere device OS updates Your app from Microsoft updates Protects your devices and your customers with certificate-based authentication of all communicationAzure Azure Sphere Other cloud or Detects emerging security threats through Security Service on-prem automated processing of on-device failures infrastructure Responds to threats with fully automated Online app and App data and telemetry OS failure reports on-device updates of OS App and App data and telemetry Allows for easy deployment of softwareOS updates updates to Azure Sphere powered devices Remote attestation & cert based authentication Azure Sphere scenario Azure DPS SIDE BAR SIDE Modernize MCU development with Azure Sphere and Visual Studio Simplify development Focus your device development effort on the value you want to create Streamline debugging Experience interactive, context-aware debugging across device and cloud Collaborate across your team Apply tool-assisted collaboration across your entire development organization Demo Deployment basics • SKUs • Components and applications • Image and Image sets SIDE BAR SIDE • Feeds • Device groups Three components.
