A state machine management component that executes on an edge device within an industrial facility is capable of discovering state machines defined on industrial controllers and translating the state machine definitions to information models that allow the state machines to be discovered and utilized by remote client applications. The edge-level information models allow the client applications to render or consume the state machine data generated by the controller, graphically render the state machines, submit commands, or set values, to the controller as state machine commands via the edge device. The edge-level system thus allows client applications with no prior knowledge of the control-level state machines to discover, retrieve, and interact with state machines defined on the industrial controllers.

An industrial control system hardened against malicious activity monitors highly dynamic control data to develop a dynamic thumbprint that can be evaluated to detect deviations from normal behavior of a type that suggest tampering or other attacks. Evaluation of the dynamic thumbprint may employ a set of ranges defining normal operation and reflecting known patterns of interrelationship between dynamic variables.

Security system for industrial control infrastructure using dynamic signatures

An industrial controller resistant to malicious attacks may provide a graduated response employing the elements of the control system to reduce access to the control system, log data, and announce intrusion based on a dynamically evolving assessment of the severity of any detected security issues.

Active response security system for industrial control infrastructure

An industrial control system providing security against tampering or modification generates periodic state thumbprints defining a state of control elements that may be forwarded to a security or safety appliance for comparison to a benchmark thumbprint indicating no tampering. The transmitted state thumbprint may capture not only programs but also configuration and environmental states of the control element.
