Security Development with an Industrial Device for SCADA System

It is not a normal occurrence that Supervisory Control and Data Acquisition (SCADA) system encountered cyberattacks. However, there has been an increase in the number of security threats as the world is progressing into Industry 4.0. As such, cyber security becomes more prominent and it is paramount to safeguard valuable information from cybercriminals as well as preventing disruptive events that can lead to devastating outcomes. This paper addresses the integration of an industrial Single Board Computer (SBC) with firewall implemented, enhancing the security of SCADA systems overall. The paper presents the details to design and implement using various software and methods to overcome the challenges/issues during the implementation. A series of performance tests have been conducted, and the results obtained have shown the good functionality and reliability of the installed firewall with SBC.
