Fault-Tolerant SCADA Systems Using ECC for Enhanced Cybersecurity and Data Integrity

This study focuses on the implementation of Error Correction Code (ECC) in Supervisory Control and Data Acquisition (SCADA) systems for a better performance of error controls and the system as well. Since the SCADA systems are fundamental in supervising industrial processes, the study focuses on the issue of error control to avoid interferences. The study proposes the Integrated Control Flow Checking or ICS-CFC methodology, which increases the reliability of SCADA systems to neutralize errors with considerably minimal overhead costs. In the critical trials performed on various simulated IT infrastructures and real ICS of industrial organizations, the proposed ICS-CFC achieved a fault coverage of 96.32% and fairly reasonable memory and performance overheads as well. The lack of additional hardware needed to implement the methodology makes it inexpensive besides enhancing already existing SCADA systems. Therefore, the analysis finds out that ICS-CFC enhances the error handling capability and reliability of SCADA and can be considered a workable solution for industries with stringent and consistent and occasional error requirements. Thus, for further ECC methods application for more variants of SCADA systems, as well as to improve operational and security features, future work is suggested.
