Internet of Things (IoT) devices/sensors/endpoints (collectively and generally IoT devices) are becoming part and parcel of many establishments. With the inbuilt support for Wi-Fi 6, also known as “AX Wi-Fi" or "802.11ax Wi-Fi,” in many IoT devices, the number of deployed IoT devices will continue grow. Wi-Fi® is trademark of the Wi-Fi Alliance. These IoT devices come from various manufacturers and will require network/Internet access for firmware upgrades. As such, there is a need to create a secure and tested firmware upgrade environment for such devices. Presented herein are techniques to track the firmware of IoT devices and use Manufacturer Usage Descriptions (MUD) to recognize the recommended firmware and settings. Further, the techniques presented herein include a mechanism to optimize firmware upgrades using Target Wake Time (TWT) scheduling.
