Abstract
Embodiments provide methods and systems for detecting rogue endpoints on a device management bus. A communications controller configured as a bus owner initiates discovery of managed devices coupled to the bus and generate a unique identifier for each managed device. The communications controller transmits a bus configuration message to the managed devices, including the respective unique identifiers. The managed devices are configured as bus endpoints based on the bus configuration message. The managed devices also capture the bus address of the communications controller from the received bus configuration message. Messages received by a managed device are authenticated as originating from the communications controller if the messages include the unique identifier provided to that managed device. The messages may be further authenticated by comparing the bus address of the message sender against the captured bus address of the communications controller.
