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 configured to process SCADA information, and at least one remote device configured to communicate with the control host. The remote device includes at least a first port and a second port wherein the first port is configured for communicating the SCADA information with said control host. The system further includes at least one modem coupled between the remote device and at least one communication line, wherein the modem is configured to allow for communication between the remote device and the at least one communication line. The inventive system still further includes a security module coupled between the modem and the second port of 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.
