Abstract
A method of tamper attempt reporting includes receiving a write attempt to configuration data stored within a field device in an industrial plant configured to run a process involving a plurality of physical process parameters including a network server, a plurality of processing units, and a plurality of field devices. The plurality of field devices include (i) a sensor for measuring at least one of the plurality of physical process parameters or (ii) an instrument for performing control output actions for at least one of the plurality of processing units. The plurality of field devices are in communication with at least one remote host system or device. The write attempt is automatically detected. An alert of the write attempt is automatically sent to at least the remote host system or device.
