VALIDATING OPERATING FIRMWARE OF A PERIPERHAL DEVICE

Various examples described herein provide for firmware verification on a peripheral device that can couple to a computing device. Before operating firmware is executed on the peripheral device, boot firmware can execute on the peripheral device and cause the peripheral device to generate a hash of the operating firmware. The peripheral device can transmit the hash to a validator external to the peripheral device, such as a management processor. The peripheral device can receive, from the validator, a validation decision based on the transmitted hash. In response to the validation decision indicating invalidity of the operating firmware, the peripheral device can execute recovery firmware to cause the peripheral device to retrieve replacement firmware. Depending on the example, the retrieved replacement firmware may replace the operating firmware or the operating firmware may be updated based on the retrieved replacement firmware.
