    Security vulnerabilities in Raspberry Pi. Analysis of hardware and software weaknesses
    (IEEE Xplore, 2019-11-01) Jorge Sainz-Raso; Martín Gutiérrez, Sergio; Díaz Orueta, Gabriel; Pancorbo Castro, Manuel
    The Internet of Things (IoT) is made up of many devices, platforms, and communication protocols. Among them, Raspberry Pi has arisen as one of the most popular equipment for hobby and education purposes because of its low cost, small size, flexibility, and potential. Nevertheless, Raspberry Pi needs an operating system to work, which exposes it to software vulnerabilities despite the many advantages it provides in comparison with nonoperating system devices. This device also has hardware limitations, which impact on its security. These limitations exist because some concessions had to be done during the design in order to decrease the cost of the device. This article analyzes different hardware and software vulnerabilities that can be found in a Raspberry Pi when using a default installation of different available operating systems. Finally, we propose a list of good practices to minimize the presented issues.

    Some engineering concepts have been proven to be very important not only in engineering degrees but in several areas. This knowledge is difficult to grasp under certain circumstances, and sometimes prior training is needed. This is a special challenge in full or part remote education. Simulations may help in this area, but truly experimental lab practices are crucial to grasp all the required knowledge and not only for fundamental information but for complex or indirect knowledge, where students can apply what they have learnt in classes. In this paper, we have worked on a concept to help professors and students to get new concepts in a more time-efficient and safe manner, using dynamic reconfiguration in Field-Programmable Analog Array. This solution can be easily applied to traditional or remote labs in less time than usual practices, so students can learn more in the same amount of time, especially when time is a constraint.
