Abstract:

A method for controlling an operation of an industrial machine that includes authenticating control commands remotely issued by command issuers through a network. The control commands each describe a modifying action to the operation of the industrial machine. The method includes: providing a jump host as a communication buffer between a unit controller of the industrial machine and the network; maintaining within a memory of the jump host whitelisted commands, the whitelisted commands including a list of the approved control commands; receiving, at the jump host, a first control command via the network; determining, at the jump host, whether the first control command is contained within the whitelisted commands; in response to an affirmative determination that the first control command is contained within the whitelisted commands, deeming the first control command as being authenticated; and transmitting the first control command to the unit controller of the industrial machine.
