Abstract:

A network system includes a central processing unit and a peripheral device in electrical communication with the central processing unit. The peripheral device has at least one power input and a data input. The network system also includes an out of band controller in electrical communication with the central processing unit, the peripheral device, and an external management interface. Responsive to an identified threat, the out of band controller is configured to disable the at least one power input and the data input to the peripheral device, where the disablement indicates to the central processing unit that a hot plug event has occurred with respect to the peripheral device. The out of band controller is also configured to enable auxiliary power to the peripheral device such that the out of band controller remains in communication with the peripheral device during remediation of the identified threat.
