A robot controller is configured to control operation of at least one industrial robot. The robot controller includes: a processor; a memory configured to store a current system configuration of the robot controller, and an editing interface configured to enable modification of the current system configuration. It further includes a stored fingerprint corresponding to the system configuration according to original manufacturer settings; and a fingerprinting interface configured to facilitate computation of a fingerprint based on the current system configuration. The stored and computed fingerprints may be compared to determine whether any modification has occurred.
