Abstract: A secure control system includes a network of multiplexers that control end/field devices of an infrastructure system, such as an electric power grid. The multiplexers have a default secure lockdown state that prevents remote access to data on the multiplexers and prevents modification of software or firmware of the multiplexer. One or more of the multiplexers include a physical authentication device that confirms the physical proximity of a trusted individual when remote access is requested. A user accesses the network and one of the multiplexers remotely by way of login credentials. The trusted individual confirms the identity of the remote user and operates the physical authentication device connected with and in proximity to that multiplexer, thereby confirming that the remote user can be trusted to access data and reconfigure the multiplexers. The multiplexer connected with the physical authentication device generates a token that is passed to each of the multiplexers that the remote user needs access to. The token may specify a time period, after which, the multiplexers will reenter secure lockdown mode.
