Abstract
Systems, methods, and articles of manufacture comprising processor-readable storage media are provided for implementing security mechanisms for network environments. For example, a method includes collecting power consumption data of a plurality of devices operating within a network and determining trust scores for the plurality of devices based, at least in part, on the collected power consumption data. The trust score for a device provides a measure of trustworthiness of the device exhibiting normal operating behavior within the network. Each device is assigned to one of a plurality of trust tiers based on the determined trust scores, wherein each trust tier specifies an authentication level for devices assigned to the trust tier. One or more authentication procedures are applied to authenticate a given device operating within the network based on the authentication level specified by the trust tier to which the given device is assigned.
