Abstract
This invention includes apparatus, systems, and methods for repairing a corrupted device still in the field by sending the corrupted device a known-good configuration derived from the majority group of devices in the field. First, an initial inventory and content scan of the device's hardware and software stack is taken. The attestation server uses the collection of results to determine a statistically known-good configuration for each type of device. The attestation server groups the known good devices by devices and ideally all of the devices of the same type are configured mostly the same. The attestation server sends an alert to the device that the device is configured differently than the plurality of existing devices. Finally, the attestation server will request a known-good configuration from one of the devices in the plurality of existing devices to repair the corrupted device in the field.
