First Claim
Patent Images
1. A system for suspension of processes in an industrial control system, comprising:
- the industrial control system network comprising at least one first controller and at least one zone, said at least one zone in communication with at least one input/output device;
a protector comprising at least one firewall; and
a switch in communication with at least one of the at least one first controller, the at least one input/output device, or the at least one firewall,wherein the switch comprises an anomaly detector, a second controller, and a database comprising emergency procedures having read-only memory.

5. A computer program product for suspension of processes in an industrial control system, comprising:
-
a non-transitory computer readable storage medium; first program instructions to detect at least one anomaly in an industrial control system network via a switch in communication with at least one firewall, wherein the switch comprises an anomaly detector, a controller, and a database comprising emergency procedures in read-only memory; second program instructions to notify the controller of the at least one anomaly; third program instructions for the controller to access the database comprising emergency procedures in read-only memory; fourth program instructions for the controller to send a stream comprising at least one emergency command through at least one firewall to at least one downstream zone; and fifth program instructions to suspend or terminate a process in the at least one zone, wherein said first, second, third, fourth, and fifth program instructions are stored on said non-transitory computer readable storage medium. - View Dependent Claims (7)
