Architecting Secure IoT applications with Azure Sphere
Azure Sphere is a secured, high-level application platform with built-in communication and security features for internet-connected devices. It comprises an Azure Sphere microcontroller unit (MCU), tools and an SDK for developing applications, and the Azure Sphere Security Service, through which applications can securely connect to the cloud and web. As we continually see more and more consumer-grade internet devices, known as the Internet of Things (IoT) Devices we need a more robust way to manage these devices in a secure way.
This course will help you learn how to plan your application and various components of your application for designing your IoT applications based on the requirements like features, scale, etc. You’ll learn how to think from the aspects of fault tolerance, robust and secure communication and data integrity over cloud platforms. You will also cover how to secure your IoT applications with the help of Azure Sphere’s built-in communication and security features for internet-connected devices.
In this course, you will learn about a newer IoT offering called Microsoft Azure Sphere. As these consumer-grade devices grow exponentially, the problem is that some of these devices are not built in a secure way, making them easily susceptible to hacking. There have been plenty of news stories about devices that have been hacked and then used for malicious purposes.
Microsoft is not alone in recognizing this issue, but they jumped on this in 2015 and began to develop an approach to securing these devices and created Microsoft Azure Sphere. This is a solution for creating highly secure internet connected microcontroller devices with 3 main components:
1) Azure Sphere Certified MCUs – They’ve got manufacturers that architect a solution that combines real-time and application processors built onto this MCU, using built-in Microsoft security technology and connectivity capabilities. They used the experience, processes, and lessons learned from looking at the Xbox consoles that have been built over the past 15 years and put that into the design of these chips. So, third-party companies can build these chips by using these processes and be certified. 2) Azure Sphere Operating System – Once an MCU is certified, you can install this operating system which is intended to be super secure and agile to serve those MCU purposes, including layers of security from Windows, Linux, and specific security monitoring software all built into that operating system.
3) Azure Sphere Security Service – This allows you to protect each device, but also allows secure communication from device to device or device to the cloud.
Similar to what we talk about with IoT and IoT Hub, but there is a certified way of doing it to ensure you’re using the architecture that will remain secure and supported by Microsoft for years to come. And this will apply to hundreds and thousands of companies that are going to build devices for all the areas mentioned above and more, giving them that secure platform to build them.
In this course, we will explore the first development kit provided by Seeed Studio along with the starter kit also provided by Seeed. This kit includes some additional modules that help provide more capability for your base kits like sensors, LCD screen, buzzers, temp/humidity sensors, and button/led for output/input capabilities. As part of this, you will explore some common use cases in manufacturing and elsewhere with some touches of personal experience the instructor had using IoT devices in production.
What you'll learn-and how you can apply it
- What makes Azure Sphere different from deploying non-certified IoT devices
- An architectural overview of the Azure Sphere ecosystem components – Devices, OS and Sphere Service
- Where to get supported devices for Azure Sphere
- The 7 properties of a secure device
- How Azure Sphere fits in with the Azure Data Platform for data aggregation
- How to deploy configurations directly and over the air (OTA)
- Setting up and configuring the Azure Sphere service
- Building your first Sphere application with the Visual Studio SDK
This training course is for you because...
You are a security professional, engineer, hobbyist or IoT architect who wish to enhance their skill set in the field of IoT, and learn how to design and deliver an IoT platform you know will be secure and supported by a trusted source.

About your instructor
Chris Seferlis is a Practice Manager with Pragmatic Works, a leader in Microsoft data analytics and cloud solutions. He has 20+ years’ experience working in IT and solving technical challenges from a business perspective. Chris is a former CIO with an MBA from UMass, bringing a mix of business acumen with practical technology solutions, primarily focusing on Business Intelligence within the Microsoft SQL stack, including MCSA and P-CSA designations. Chris is a US Army Veteran having served as the Battalion Liaison for the Directorate of Information Management while deployed in support of Operation Enduring Freedom. Using early iterations of IoT devices like Raspberry PIs, Chris was able to implement solutions that captured data from the manufacturing floor using scales for capturing weights and card readers for capturing transactions. This data captured was then transformed and used for disseminating information about operational productivity and plant-floor operations. With this previous experience, Chris is able to translate business needs to technology implementations with IoT solutions; Azure Sphere is one of the newer and more secure platforms and other Azure Data Platform components required to build a complete solution.
