1. A computing device, comprising: a trusted environment comprising: a trusted hardware processor; and a trusted memory for storing executable instructions, the trusted hardware processor executing the executable instructions to provide a trusted computing environment; a legacy environment comprising: a legacy hardware processor that is physically separated from the trusted hardware processor; and a legacy memory for storing executable instructions, the legacy hardware processor executing the executable instructions to provide a legacy computing environment; a network hardware interface that is dedicated for the trusted environment, the network hardware interface being inaccessible to the legacy environment; and input/output (I/O) devices, wherein each of the I/O devices comprises dedicated connections for the trusted environment, each of the I/O devices being inaccessible to the legacy environment; wherein the trusted environment receives input from the I/O devices and the network hardware interface and monitors, compares, evaluates, blocks, processes or modifies the received input for transmitting to the legacy environment; wherein the trusted environment monitors, compares, evaluates, blocks, processes or modifies input received from the legacy environment for transmitting to the I/O devices and the network hardware interface; wherein the trusted hardware processor utilizes a hardware gated channel to control computing functions of the legacy environment; and wherein the legacy environment executes safe applications to generate output in a structured form.
