Space Cybersecurity and Resilience Engineering

Space cybersecurity is one of the most critical and rapidly evolving fields in modern defence and critical infrastructure protection. As humanity's dependence on satellite systems grows — spanning communications, navigation, Earth observation, financial services, and military operations — the security of these assets has never been more important. XCOM Space specialises in the cyber resilience of space systems, GNSS infrastructure, and the ground segments that underpin them.

Satellites and their supporting ground infrastructure are increasingly targeted by sophisticated nation-state actors and cybercriminal groups. Attacks against space systems can have cascading consequences across every sector that depends on satellite-derived services. GPS jamming and spoofing, command-and-control link hijacking, denial-of-service attacks against ground stations, and supply chain compromises of space hardware represent a growing threat landscape that demands specialised expertise.

The GNSS Threat Landscape

Global Navigation Satellite Systems (GNSS) — including GPS, Galileo, GLONASS, and BeiDou — form the invisible backbone of modern society. Timing signals from these constellations synchronise financial markets, power grids, telecommunications networks, and transportation systems. A successful cyberattack or coordinated jamming campaign targeting GNSS infrastructure can disrupt critical services far beyond simple navigation. XCOM Space builds threat intelligence frameworks and resilience strategies tailored specifically to the GNSS threat environment.

Cyber Range Simulation for Space Systems

Understanding how adversaries attack space systems requires purpose-built simulation environments. XCOM Space develops cyber range platforms that model the full kill chain of attacks against satellite and ground infrastructure. These environments allow defenders to test detection capabilities, validate resilience strategies, and train operators without risk to live systems. Our research into adversary emulation draws on frameworks such as SPARTA and ESA SPACE-SHIELD to ensure simulations reflect real-world threat actor behaviour.

Mission Security by Design

Security cannot be bolted onto space missions as an afterthought. XCOM Space advocates for and develops mission security architecture from the earliest design phases, embedding defence-in-depth principles across the space, link, and ground segments. Our mission security design capability draws on international standards and emerging frameworks to ensure that satellite missions are hardened against both current and future adversarial threats. We work to integrate security assurance processes that persist throughout the full mission lifecycle — from concept through to end-of-life decommissioning.

Research and the Future of Space Security

The intersection of space operations and cybersecurity is a nascent but rapidly maturing field. XCOM Space contributes to the global body of knowledge through applied research in adversary deception, anomaly detection for space telemetry, and the development of threat intelligence methodologies suited to the unique characteristics of orbital systems. Our research is grounded in operational realism, aiming to produce findings and tools that have direct applicability to the space security community.

As the commercial space sector expands with low-Earth-orbit constellations, in-orbit servicing missions, and lunar infrastructure programmes, the attack surface for adversaries continues to grow. XCOM Space is committed to advancing the science and practice of space cybersecurity to ensure that the systems humanity relies on remain secure, resilient, and trusted — today and into the future.
