Business Challenge

Secure the end-to-end IoT communication ecosystem of 80 nanosatellites

Solution

CYSEC LAB security evaluation and architecture design services

Customer

astrocast

Astrocast is Switzerland’s first commercial satellite-telecom operator. In collaboration with European Space Agency, Airbus, and Thuraya, Astrocast is building a constellation of 80 nanosatellites with an objective to provide two-way IoT communications services at low cost.

Challenge

Astrocast required a secure-by-design approach to their product architecture; their business model depends on the security of their IoT ecosystem. Security needs to cover a vast system: a two-way chain of communication from the mission control center, via the satellites, to their client’s terminals.

Engagement

CYSEC-Case-Studies-2

Step 1

CYSEC LAB carried out a risk assessment of Astrocast’s complex product architecture, taking into account multiple ecosystem constraints. The team delivered a prioritized list of risks and a mitigation plan for each of them.

Step 2

Based on the threat model, risk analysis, and risk trade-off, CYSEC developed the architecture design for their security solution.

Outcome

Within 5 months, CYSEC had designed the security architecture. Security is thereby ensured end-to-end: from Astrocast’s customers, through the 80 nanosatellites of the constellation, all the way to the IoT terminals on ground and at sea.
