During the last decades, the space sector has gone through many changes; more private actors have joined, the dependence on space assets has increased, and the threat of cyberwarfare and private cyber attacks is growing. With this recent development, one wonders how we can ensure cyber security in such a specific industry. This is a multifaceted matter since there is a need to have technical solutions and to ensure that stakeholders take their responsibility, both of which will be considered in this thesis. Thirteen qualitative interviews with Swedish space stakeholders were conducted to understand the current industry landscape and which aspects should be prioritised for the future. We found that all Swedish actors must begin to cooperate, both state and businesses should contribute to a change in priority and technical experts should have more influence. The results were also applied and evaluated with the Multistakeholder Model. We examined distributed ledger technology and which adjustments were needed to make it applicable to satellites to include a technical aspect. We found that an update of the underlying structure and the choice of Proof of Stake as a consensus method could make distributed ledgers less demanding of computational power and storage.
