An image capture device for a secure industrial control system is disclosed. In an embodiment, the image capture device includes: an image sensor; a signal processor coupled to the image sensor; and a controller for managing the signal processor and transmitting data associated with processed image signals to at least one of an input/output module or a communications/control module via a communications interface that couples the controller to the at least one of the input/output module or the communications/control module, wherein the controller is configured to establish an encrypted tunnel between the controller and the at least one of the input/output module or the communications/control module based upon at least one respective security credential of the image capture device and at least one respective security credential of the at least one of the input/output module or the communications/control module.

Operator actions and/or other commands or requests are secured via an authentication path from an action originator to a communications/control module or any other industrial element/controller. In implementations, an industrial control system includes an action authenticator configured to sign an action request generated by the action originator. The destination communications/control module or any other industrial element/controller is configured to receive the signed action request, verify the authenticity of the signed action request, and perform a requested action when the authenticity of the signed action request is verified.
