Diagnosing a device in an automation and control system

摘要

A method of diagnosing a device (12) in an automation and control system (10) comprises the steps of: instantiating a first and a second virtual machine (30a, 30b) managed by a hypervisor (28), the first and second virtual machine sharing hardware resources (26) of the device (12); enabling, by the hypervisor (28), a read-only access from the first virtual machine (30a) to the second virtual machine (30b); running an industrial automation and control system application (38) in the second virtual machine (30b); and running a diagnosing application (34) in the first virtual machine (30a) configured to analyze the second virtual machine (30b) and to identify threats to the industrial automation and control system application (38).
