Abstract: In one embodiment, a request may be received to load firmware on a microcontroller of a device. A firmware transfer may be initiated to load the firmware on the microcontroller. Data traffic may be monitored at one or more locations on a communication path associated with the firmware transfer. It may be determined whether the data traffic matches a digital fingerprint associated with the firmware.

Abstract: In one embodiment, a request may be received to load firmware from an external component to a microcontroller of a device. The external component may be authenticated, and the firmware may be loaded from the external component to the microcontroller using a firmware loading controller of the device, wherein the firmware is loaded using direct memory access without accessing system memory associated with the device.
