01What is a ground segment security engineer?
A ground segment security engineer secures the ground stations, networks, and control systems that command satellites and receive their data.
The ground segment is the part of a space system on Earth, and it is the largest attack surface a space platform has. The ground segment security engineer hardens that infrastructure, defends the control systems that send commands to spacecraft, and protects the telemetry and command links between the ground and the satellite.
02What does the role do?
- Harden ground station networks and mission control systems against intrusion.
- Secure the telemetry, tracking, and command links between ground and spacecraft.
- Monitor ground infrastructure for compromise and respond to incidents.
- Manage access to command and control systems and enforce least privilege.
03Skills and how to enter
Most enter from network or security engineering or from ground operations, then add space-domain training such as a Foundations in Space and Cybersecurity certification.
Core skills: Network security, control system security, satellite ground systems, telemetry tracking and command, detection and incident response.
This role is one part of the work of space cybersecurity, operations and resilience platform professionals. To learn the foundations, see what a space career academy is.
