Once a novelty, small satellites, often referred to as CubeSats, have become important tools for a variety of space activities ranging from exploration to defense. Their relative affordability and short development timeline have made them attractive options to complement larger space vehicles, conduct reconnaissance and other finite tasks. The specialized nature of many CubeSat missions do not make their security any less important as their missions could easily be matters of national security. This paper demonstrates the use of attack tree analysis to assess vulnerabilities of a CubeSat. First, we abstract and build an architectural model of an operational CubeSat. We then create a series of attack trees for the abstracted architecture to illustrate a series of potential attack vectors for small satellites. We conclude by discussing some strategies that could be employed to improve CubeSat resilience.
