Abstract: A standalone security device comprises a first removable interface for connecting the standalone security device to a network. A second removable interface connects the standalone security device to at least one hardware device. The first removable interface and the second removable interface provide an electrical connection between the network and the at least one hardware device. A first reconfigurable microcontroller and a second reconfigurable microcontroller are electrically connected to each other between the first and second removable interfaces. A reconfigurable computer-on-module (COM) is electrically connected to the first reconfigurable microcontroller and the second reconfigurable microcontroller. The reconfigurable COM implements security protocols for communications between the network and the at least one hardware device.
