Embedded data protection and forensics for physically unsecure remote terminal unit (rtu)

Abstract

Systems and methods include a method for protecting data for a remote terminal unit (RTU) and providing audit trail information for forensics procedures. Monitoring is performed for conditions detected at an RTU that warrant a data protection operation at the RTU. The monitoring is performed by an instrumented security function (ISF) chip communicating with the RTU in a supervisory control and data acquisition system (SCADA) network. Upon determining that conditions are warranted, the data protection operation is initiated by the ISF chip. The system also provides audit trail information for forensics procedures upon detecting a threat in the vicinity of the RTU. The system invokes the forensics procedure by initiating the localization services (HBL) embedded as part of the RTU's disk apparatus triggered by a change to the disk apparatus such as a power disconnect or by receiving a security signal from the NAC or local occupancy sensors.
