In the world of connected devices, securely updating firmware Over-the-Air (OTA) is a critical capability for IoT and embedded systems. However, ensuring the safety, integrity, and efficiency of OTA firmware updates remains a complex and technical challenge. 

 Without robust security measures, firmware updates are vulnerable to unauthorized access, data corruption, and potential breaches—problems that can lead to compromised devices and reputational damage.

AWS offers a robust and reliable cloud platform for firmware storage and distribution. With AWS S3, IAM permissions, and CloudFront’s global CDN, you can ensure your firmware is not only securely stored but efficiently delivered worldwide. AWS simplifies device management and scalability, giving you confidence that your OTA update system can grow alongside your deployments.

Security is paramount for OTA updates, and this is where SSL/TLS shines. SSL/TLS, provides encryption and authentication, ensuring that firmware data transferred over WiFi remains protected from unauthorized access and tampering. In this course, you’ll understand and implement SSL/TLS on your ESP32, making each firmware update secure and resilient.

This course is perfect for embedded systems engineers, IoT developers, and firmware designers who want to build or improve OTA update systems with high security and reliability.

If you’re an intermediate to advanced developer looking to enhance your skills with a practical, cloud-based OTA solution, this course will provide you with the knowledge and techniques necessary to implement a fully functional, secure OTA system.

This course bridges the gap between cloud technologies and embedded systems by providing hands-on experience with AWS’s powerful tools. With this knowledge, you’ll be equipped to build secure, reliable OTA update solutions that protect devices from threats while improving user experience through efficient, seamless updates.

With the growing demand for IoT devices, the ability to securely update firmware over the air is no longer optional—it’s essential. By mastering OTA updates with AWS and SSL/TLS, you position yourself at the forefront of the embedded systems field. Whether your focus is on industrial devices, consumer electronics, or smart home solutions, Secure Firmware OTA Update with AWS: SSL/TLS Connection will ensure you have the skills to secure the future of connected devices.

A little about me : Israel Ninsaw Gbati

This is my private channel. 

I have been writing embedded firmware for years, I have built embedded devices like consumer products and robotic arms.

 firmware development online till date

...including third year undergraduate university students in-person.

If you have taken any of our courses before you will know I start from the absolute basics, I do not assume that the student has any prior knowledge of the topic under discussion. You will also know that by the end of the course you understand the functions of every register used in developing the particular firmware or driver.

This method is the same for all of my published embedded systems courses.
