METHODS, SYSTEMS AND DEVICES FOR SECURING SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) COMMUNICATIONS

摘要

A secure supervisory control and data acquisition (SCADA) system is presented. The inventive system includes a SCADA control host system configured to process SCADA information, and at least one remote device configured to communicate SCADA information with the control host system. The inventive system further includes a modem coupled between the at least one remote device and a communication line, wherein the modem is configured to allow for communication between the remote device and the communication line. The system further includes a security module coupled between the modem and the remote device. The security module is configured to control access to the remote device by a user seeking access thereto from the communication line through the modem.
