Towards A Secured SCADA Architecture: A DNP3 Test Case

The foundation of a country's critical infrastructures (CI), which provide crucial services, is its security, healthcare, and economic systems. By lowering CI's operational costs and associated expenses and enhancing its effectiveness and safety, appropriately functional CI infrastructure plays an essential role in the prosperity of the nations. To do so, businesses that manage CIs frequently combine the Internet of Things (IoT) with Cyber-Physical Systems (CPS), such as SCADA systems. SCADA systems were not initially built with web security in mind, exposing CIs open to security risks. National security issues can arise when these technologies are connected to power plants and water treatment facilities. This study aims to demonstrate how security features can be implemented in DNP3-based SCADA infrastructures. By creating a functional configuration and consensus amongst the communicating devices, the DNP3 protocol will support digital signatures. The team proposed a SCADA architecture to accomplish this, making it possible for these systems more secure manner.

The foundation of a country's critical infrastructures, including security, healthcare, and economic systems, plays a crucial role in national prosperity. Combining the Internet of Things (IoT) with Cyber-Physical Systems (CPS), such as SCADA systems, can enhance the effectiveness, safety, and cost efficiency of critical infrastructures. However, the connection of these technologies to power plants and water treatment facilities can pose security risks. This study focuses on implementing security features in DNP3-based SCADA infrastructures to ensure a more secure environment.
