Securing the space-based assets of NATO members from cyberattacks

Julia Cournoyer

The increased dependence on space-based assets for both military and civilian functions has turned these critical systems into a potential target for cyberattacks. NATO’s deterrence capability relies on these assets, such as satellites, for secure communication, navigation, intelligence and early warning systems.

Protecting space-based assets requires a coordinated and proactive cybersecurity strategy. This paper proposes a three-tiered framework – based on mitigation, adaptation and resilience – for strengthening NATO’s space cybersecurity approach.

As defence commitments among NATO allies shift, ensuring the long-term stability of space security cooperation within the alliance will be critical for sustaining collective deterrence and operational resilience.
