Abstract

See full text

A network device is provided and operative to secure remote access to an internal component including a processor and/or a register. The network device includes an Ethernet interface, an access port, and a controller. The Ethernet interface receives, from a host device, frames transmitted over an Ethernet network. The access port is physically connected to the internal component and physically inaccessible to the host device. The controller is physically connected to the access port. The controller: accesses the internal component via the access port; based on the frames, determines whether the host device is authorized; if the host device is not authorized, prevent the host device from accessing the processor or the register; and if the host device is authorized, permit the host device, via the Ethernet interface and the access port, to control operation of the processor or change the contents of the register.
