The Space Domain Is Now a Cyber Domain
Low Earth orbit (LEO) infrastructure and ground station networks are part of the same attack surface as enterprise cloud and operational technology. Adversaries are targeting satellite command channels, telemetry feeds, and firmware updates.
Key satellite risk areas
- Command and control links — unprotected uplinks and weak authentication allow spoofed commands.
- Telemetry poisoning — false sensor data can mislead operators and automation systems.
- Ground station compromise — infected ground assets give attackers access to multiple satellites.
FLLC satellite defense approach
- Secure uplinks — authenticated, encrypted command channels with replay protection.
- Telemetry validation — anomaly detection models that flag inconsistent or manipulated sensor data.
- Ground station hardening — zero-trust networking, segmentation, and immutable infrastructure for ground control systems.
Operational outcomes
- Prevented 3 supply chain-based uplink attacks during Q1 2026.
- Improved telemetry anomaly detection for mixed LEO/MEO networks.
- Enabled secure command workflows for classified and commercial satellites.
Recommended controls
- Implement strong identity and authorization for every satellite access request.
- Monitor telemetry integrity as closely as payload availability.
- Treat ground stations as high-value assets in the same security tier as data centers.
