This is no longer the case and poses a major security concern (Schalk et al., 2022, p. 350). Up until the recent commercial boom in the space industry and the open sourcing of cFS, most of the details about satellite hardware and software was limited to the government and military. This closed system had a high barrier to entry and significantly limited the amount of research possible into satellite systems (Schalk et al., 2022, p. 351). Most ASAT research now focuses on the electronic and jamming aspects via hypothetical scenarios on unsecured satellites, but when it does focus on cyber security vulnerabilities in satellite systems has mainly focused on protocols, encryption, and credential management, which means the focus is on the *data-link* side and not in the systems architecture. There are opportunities to focus on cyber ASAT as it is cheap and can take place in "non-hypothetical" scenarios in which real satellites are accessed (Schalk et al., 2022, p. 350). --- ## References 1.
