SYSTEM AND METHOD FOR REDUCING CYBER CRIME IN INDUSTRIAL CONTROL SYSTEMS

摘要

User permissions for an industrial control system are stored in a unified permissions database connected to a network in common with the industrial control system. The permissions database stores user permissions for logical assets on or attached to the network. Physical devices used for industrial control are connected to the network via virtual control devices that convert messages from protocols used by the physical devices into the suite of internet protocols, and vice versa. Control of the physical devices is via a remote computer that permits control according to permissions stored in the database.
