SECURE END-TO-END PERMITTING SYSTEM FOR DEVICE OPERATIONS

摘要

A permitting system for controlling devices in a system includes a permit issuing agent that receives a command to be sent to a device. Based upon at least one attribute of the command, the permit issuing agent identifies one or more business logic modules that is pertinent to the command. Each business logic module has a respectively different set of business rules associated with it. Each identified business logic module determines whether the command complies with the business rules associated with that module. If the command is determined to comply with the business rules of all of the identified business logic modules, the agent issues a permit for the command, and the permit is sent to the device for execution of the command.
