The SPARTA (Space Attack Research and Tactic Analysis) Framework was used to identify the tactics, techniques, and associated countermeasures associated with the experiment/attack.

They utilized the SPARTA Navigator tool to construct the attack chain and generated an Excel export to pinpoint relevant countermeasures. Subsequently, a thorough analysis is conducted to ensure the applicability of the associated countermeasures to the specific Tactics, Techniques, and Procedures (TTPs).

The SPARTA Navigator proves invaluable in presenting a comprehensive array of countermeasures categorized by defense-in-depth, effectively minimizing the risk posed by TTPs. By leveraging the SPARTA Navigator, we successfully map the attack chain to SPARTA TTPs, as exemplified below.

Upon exporting the data from the SPARTA Navigator, they have identified eight countermeasures. Out of these, five pertain to terrestrial countermeasures intended to prevent vulnerable software from infiltrating the spacecraft. The remaining three countermeasures are implemented onboard the spacecraft itself, serving to protect against and/or detect the TTPs executed during the experiment.
