Abstract

An industrial control systems to control industrial processes and production, there is provided a monitoring assembly for such an industrial control system. The monitoring assembly comprises an industrial control system that includes a communications device which is connectable to a communications network and which is configured to attempt to send a request via the communications network to an internet address. The monitoring assembly also includes a monitoring apparatus that is configured to detect communication of the communications device with the internet address and following such detection provide an alarm notification including an indication that the industrial control system is connected to the Internet.

Claims

1. A monitoring assembly for an industrial control system comprising:

an industrial control system including a communications device connectable to a communications network and configured to attempt to send a request via the communications network to an internet address; and

a monitoring apparatus configured to detect communication of the communications device with the internet address and following such detection provide an alarm notification including an indication that the industrial control system is connected to the Internet.

2. A monitoring assembly according to claim 1 wherein the monitoring apparatus includes a first monitoring submodule configured to detect communication of the communications device with the internet by detecting receipt of a response from the internet address to the request.

3. A monitoring assembly according to claim 2 wherein the first monitoring submodule is located within the industrial control system.

4. A monitoring assembly according to claim 2 wherein the first monitoring submodule is configured to provide an alarm notification within the industrial control system.

5. A monitoring assembly according to claim 1 wherein the monitoring apparatus includes a second monitoring submodule configured to detect communication of the communications device with the internet address by detecting receipt of the request.

6. A monitoring assembly according to claim 1 further including a fixed internet server which defines the internet address.

7. A monitoring assembly according to claim 6 wherein the second monitoring submodule is located within the fixed internet server.

8. A monitoring assembly according to claim 6 when dependent on claim 2 or any other claim dependent thereon, wherein the first monitoring submodule is configured to communicate the alarm notification to the fixed internee server.

9. A monitoring assembly according to claim 6 wherein the fixed internet server is configured to identify the owner of the industrial control system indicated as being connected to the Internet and to notify the owner of the said industrial control system that the said industrial control system is so connected.

10. A monitoring assembly according to claim 9 wherein the fixed internet server is configured to identify the owner of the industrial control system indicated as being connected to the Internet based on information provided to it by the communications device of the said industrial control system.

11. A monitoring assembly according to claim 1 wherein the communications device is configured to attempt to send a first request via the communications network to a first internet address and a second request via the communications network to a second internet address, and the monitoring apparatus is configured to detect communication of the communications device with either of the first and second internet addresses and following such detection provide the alarm notification.
