Field device having tamper attempt reporting

摘要

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.

1. A method of tamper attempt reporting, comprising:
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 said field devices, said plurality of field devices including (i) a sensor for measuring at least one of said plurality of physical process parameters or (ii) an instrument for performing control output actions for at least one of said plurality of processing units, said plurality of field devices each being in communication with at least one remote host system or device; said field device automatically detecting said write attempt, and said field device automatically sending an alert of said write attempt to at least said remote host system or device; wherein said plurality of field devices further include a memory, wherein an Automatic Tamper Attempt Reporting (ATAR) algorithm is stored in said memory, said ATAR algorithm having executable code for said automatically detecting said write attempt and said automatically sending said alert, and wherein disabling of said ATAR algorithm results in automatically sending an alert to said remote host system or device.
