Organisations must treat space infrastructure as part of their cyber perimeter, experts warn

As mission control, satellites and ground networks become woven into the same digital ecosystem as cloud services and enterprise IT, security practitioners warn that businesses are exposed to a new, three-dimensional attack surface that reaches into low‑Earth orbit.

Why space matters to ordinary organisations

Space is no longer an exotic domain reserved for governments and a handful of aerospace firms. Modern commerce and public services increasingly rely on space-based capabilities such as navigation, communications and time‑synchronisation. That dependency means an incident targeting orbital assets can cascade into tangible disruptions on Earth, affecting everything from mobile backhaul and logistics to financial transactions.

Changing shape of the attack surface

The traditional model of perimeter defence — where organisations harden offices, data centres and corporate networks — is insufficient when the infrastructure they depend on spans terrestrial networks and satellites. This is a multi-layered problem: vulnerabilities can exist in satellite hardware, ground stations, the software that orchestrates the fleet, or within the terrestrial links that connect space assets to enterprise systems. Compromise at any of these points can be exploited to interfere with service availability, integrity or confidentiality.

Intelligence warnings and recent incidents

Governments are already taking note. A joint intelligence assessment from several allied nations has highlighted a rise in cyber operations directed at low‑Earth orbit systems. Incidents involving major organisations, including the reported breach at the European Space Agency, underline that actors are prepared to target space infrastructure as part of broader campaigns.

What organisations should do

Security teams must expand their threat models and operational practices to reflect this reality. Practical steps include:

• Mapping dependencies on space services across business functions and supply chains.
• Engaging with providers to understand security controls for satellites, ground stations and comms links.
• Integrating space‑component risk into incident response and continuity plans.
• Prioritising resilience for services that rely on low‑latency or direct‑to‑device links.

Consequences and the wider picture

Treating space as part of an organisation’s attack surface does not require every enterprise to become a space operator. Instead, it demands that boards and security teams acknowledge the systemic dependencies on orbital systems, and that procurement, risk and technical teams ask harder questions of suppliers. As missions such as Artemis II signal renewed strategic focus on space, the domain is becoming an arena for both opportunity and confrontation. Preparing now reduces the chance that a disruption in orbit becomes a business‑critical incident on the ground.
