Abstract

This culminating experience sought to lay the foundation for a miniaturized physical SCADA testbed to be built at California State University San Bernardino to enable students to apply the cybersecurity knowledge, skills and abilities in a fun and engaging environment while learning about what SCADA is, how it works, and how to improve the security of it. This project was conducted in response to a growing trend of cybersecurity attacks that have targeted our critical infrastructure systems through SCADA systems which are legacy systems that manage critical infrastructure systems within the past 10 years. Since SCADA systems require constant availability, it makes it hard to test the security of these devices which is why testbeds have been designed to analyze how a cyber-attack affects these systems in a safe environment. To build a SCADA testbed at CSUSB this project designed a requirements documentation based on the following questions so that the next person that wants to accomplish this task can take the requirements outlined and build a miniaturized physical SCADA testbed. To craft the appropriate requirements documentation this project aimed to answer the following questions: Q1. How can a miniaturized SCADA testbed be built for a school environment using open-source architecture? Q2. What critical infrastructure sectors can be easily implemented into a physical SCADA testbed? Q3. Which cyber-attacks can be easily replicable in a SCADA scenario-based environment? Q4. How should SCADA scenarios be modeled for an implementation into this testbed? To answer these questions, research was conducted utilizing scholarly articles on currently available SCADA testbeds, conducted interviews with individuals that have built SCADA testbeds, and distributed a survey to different SCADA professionals to build a requirement documentation for the miniaturized SCADA testbed, which included functional and nonfunctional requirements, use case diagrams and detailed use cases. After gathering the data from 3 different interviews with SCADA professionals and aggregating responses of the surveys we crafted a requirements documentation which includes a requirements documentation, detailed use cases, use case diagrams, and a classes and relationship chart so that the next individual who works on this project can use these ideas and begin construction of a miniaturized SCADA testbed at CSUSB.
