1. An apparatus, comprising:
- a processor configured to control one or more functions of a network device having a network interface, wherein the network device is configured to receive data requests and an encrypted form of management requests via the network interface, wherein the management requests are from a remote administrator;
a first bus; and
a bus controller coupled to the processor via the first bus, wherein the bus controller is also coupled to a second bus of the network device that is distinct from the first bus, wherein the bus controller is configured to receive the encrypted form of the management requests from the second bus, and to convey the encrypted form of the management requests to the processor via the first bus;
wherein the processor is configured to decrypt the encrypted form of the management requests, wherein the network device includes a processor configured to facilitate operation of the network device, and wherein the processor of the apparatus is distinct from the processor included in the network device.

12. A method, comprising:
-
receiving, by a bus controller of a management device, an encrypted form of management requests via a first bus of a network device having a network interface, wherein the network device received the encrypted form of the management requests and data requests via the network interface, wherein the management requests are from a remote administrator; conveying the encrypted form of management requests from the bus controller to a processor of management device via a second bus of the management device, wherein the network device includes a processor configured to facilitate operation of the network device, and wherein the processor of the management device is distinct from the processor included in the network device; decrypting, by the processor, the encrypted form of the management requests; and controlling, by the processor, one or more functions of the network device according to the management requests. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
