Abstract
According to one embodiment, an apparatus may store: a hard token representing identification information of the device, a network token representing the status of a network, and a resource token representing information associated with a resource. The apparatus may further store secured copies of the hard token, network token, and resource token. The apparatus may receive a suspect token indicating a risk that at least one of the device, the network, and the resource has been tampered, and in response, determine to inspect at least one of the hard token, network token, and resource token. The apparatus may then compare the at least one of the hard token, network token, and resource token with its corresponding secured copy. If at least one of those tokens does not match its corresponding secured copy, the apparatus may communicate a revalidation token indicating at least one token has been tampered.
