Satellites, now numbering over 10,000 as of 2024 [43], have transitioned from extraordinary space achievements to common orbital fixtures, especially with the surge in small satellites like CubeSats and nanosatellites. This accessibil- ity has allowed diverse entities, including universities and startups, to engage in space projects. However, the ease of developing these smaller satellites often comes at the cost of security, making them prone to cyberattacks. Teams be- hind these projects may lack comprehensive cybersecurity knowledge, leading to significant vulnerabilities. Furthermore, the evolving nature of cybersecurity means satellite software can quickly become outdated, with updates in orbit posing a challenge, as noted in research like Willbold et al. [47]. Concurrently, there has been a significant evolution in satellite on-board computing, particularly in processing power. This advancement enables small satellites to run full operating systems like Linux, a shift from the basic systems in earlier models. This technological progress enhances satellite func- tionalities but also adds complexity and vulnerability, neces- sitating stronger security measures. As systems become more sophisticated, they are more susceptible to threats, requiring a layered defense approach. Sandboxing is one of the effective methods to isolate software vulnerabilities and protect these advanced systems. In this paper, we discuss the process of selecting a sandbox- ing mechanism for a satellite project currently under develop- ment, named RACCOON [41]. The project's goal is to design
