Abstract: A cloud management system and methods for operating the same provide for management of large deployments of networked devices and Internet of Things devices. The system provides multi-factor authentication of devices by the use of both permanent digital certificates installed in devices at time of manufacture and temporary cryptographic keys that may be revoked or changed as needed.

Abstract: A method is for generating a graphic interface for monitoring a plurality of network nodes in a network. The network nodes include a plurality of master nodes and a plurality of non-master nodes each being managed by one of the master nodes. In the method, an electronic device executes the steps of: establishing a connection with one of the master nodes that serves as a root node; obtaining a first packet, from each of the network nodes, and obtaining a second packet from each o f the non-master nodes within a management hierarchy of the root node; generating synthesized status data associated with each of the network nodes based on the corresponding one of the packets; and generating the graphic interface containing the synthesized status data.
