Claim Text:
1. A method to identify a degradation of integrity of a process control system, the method comprising: monitoring, with a processor, a file on a file system of the process control system; verifying, with the processor, if the file is identified in a system profile, the system profile identifying files expected to be present on the file system; identifying, with the processor, a degradation of integrity of the process control system when the file is not identified in the system profile; alerting a process control system provider when the degradation of integrity is identified to indicate that a process control system administrator has attempted to modify the process control system, the process control system provider to supply the process control system to the process control system administrator; and terminating an illegitimate process associated with the file identified in the system profile when the degradation of integrity is identified.
