    Exploring IoT Vulnerabilities in a Comprehensive Remote Cybersecurity Laboratory
    (MDPI, 2023) Delgado, Ismael; San Cristóbal Ruiz, Elio; Martín Gutiérrez, Sergio; Robles Gómez, Antonio
    With the rapid proliferation of Internet of things (IoT) devices across various sectors, ensuring robust cybersecurity practices has become paramount. The complexity and diversity of IoT ecosystems pose unique security challenges that traditional educational approaches often fail to address comprehensively. Current curricula may provide theoretical knowledge but typically lack the practical components necessary for students to engage with real-world cybersecurity scenarios. This gap hinders the development of proficient cybersecurity professionals capable of securing complex IoT infrastructures. To bridge this educational divide, a remote online laboratory was developed, allowing students to gain hands-on experience in identifying and mitigating cybersecurity threats in an IoT context. This virtual environment simulates real IoT ecosystems, enabling students to interact with actual devices and protocols while practicing various security techniques. The laboratory is designed to be accessible, scalable, and versatile, offering a range of modules from basic protocol analysis to advanced threat management. The implementation of this remote laboratory demonstrated significant benefits, equipping students with the necessary skills to confront and resolve IoT security issues effectively. Our results show an improvement in practical cybersecurity abilities among students, highlighting the laboratory’s efficacy in enhancing IoT security education.

    Vulnerability Assessment of Learning Management Systems
    (Institute of Electrical and Electronics Engineers (IEEE), 2023-03-21) San Cristóbal Ruiz, Elio; Pastor Vargas, Rafael; Gil Ortego, Rosario; Meier,Russ; Saliah-Hassane, Hamadou; Castro Gil, Manuel Alonso
    This paper presents a vulnerability assessment of a class of web applications designed to serve educational coursework to online users. We describe the deployment landscape, the known vulnerabilities institutions must be aware of, and document how non-supervised deployment puts institutions at risk from cybercriminals.

    Cost-Effective Arduino-Based SPWM Control of an Inverter for Training Menacho
    (IEEE Xplore, 2021-12) Menacho, Antonio; Blázquez Merino, Manuel; Plaza,Pedro; San Cristóbal Ruiz, Elio; Martín Gutiérrez, Sergio; Clara Pérez; Manuel Castro; Ramón Carrasco Borrego
    In this work, a cost-effective sine pulse-width modulation (SPWM) control of an inverter has been implemented using Arduino UNO microcontroller, which can be used with various power stages. The proposed model is focused on power electronics training or learning. It allows users to practice the control of an inverter without the need to be in a face-to-face laboratory. The proposed model facilitates remote experimentation to acquire the required knowledge or competencies.

    Smart Grid: Assessment of the past and present in developed and developing countries
    (ELSEVIER, 2017) Ponce Jara, Marcos Antonio; Ruiz Larrocha, Elena; Gil Ortego, Rosario; San Cristóbal Ruiz, Elio; Pérez Molina, Clara María; Castro Gil, Manuel Alonso; https://orcid.org/0000-0002-4450-4740
    The modern struggle to generate electricity reducing our dependence on fossil fuels and decreasing greenhouse gas emissions has found an ally in Smart Grid technology. This new trend involves a renewed perspective on how to generate, transmit, distribute and manage electricity networks, which not only helps to reduce power demand and cost, but can also improve efficiency, reliability, quality and security. This paper aims to study comprehensively the Smart Grid power system by comparing experiences and success stories from around the world. Developed countries, like the United States and those in the European Union, and developing countries, like India and Brazil, have been taken as examples of the current development and state of the Smart Grid concept. Europe and the U.S. lead the development of Smart Grids systems, while Brazil and India strongly depend on foreign technology and investment for their development in their countries. Climate change represents an extra challenge for developing countries, in addition to other issues related to economic and social advancement. Nevertheless, Smart Grids offer an array of possibilities and opportunities that work towards climate change international goals. However, state motivations and national energy resources limit the advancement of Smart Grids on this matter.
