The space domain has become increasingly important for communication, navigation, remote sensing, and other applications. However, it also faces growing cybersecurity threats that can disrupt or disable space-based assets, jeopardizing national security, critical infrastructure, and economic activities. In this article we will explore the challenges of ensuring cybersecurity in the space domain, with a focus on the new EU Space Strategy for Security and Defence, the NIS 2 directive of the EU, and recent cybersecurity threats to the space industry.
Overview of the Space Branch
The space industry encompasses various sectors, such as satellite manufacturing and operation, launch services, ground segment equipment, and downstream services. Each sector has its own cybersecurity risks and vulnerabilities, ranging from insider threats and supply chain attacks to malware infections and denial-of-service attacks. For example, a cyber-attack on a satellite’s command and control system can disrupt its operation or even render it useless, causing financial losses, data breaches, or public safety hazards. Recent cyber-attacks on the space industry and space programmes include the 2018 breach of NASA’s Jet Propulsion Laboratory, the 2019 hack of an Indian satellite communications agency, and the 2020 attack on a European space contractor.
The space industry is divided into several sectors, including:
- Space Exploration: This sector includes activities related to the exploration of space, including satellite missions, deep space exploration, and human spaceflight.
- Space Applications: This sector includes the use of space assets for applications on Earth, such as satellite telecommunications, Earth observation, and navigation.
- Space Transportation: This sector involves the development and operation of launch vehicles, spacecraft, and related infrastructure.
- Space Manufacturing: This sector involves the development and manufacture of space-related hardware and equipment.
Each sector of the space industry is crucial for the functioning of the space economy with unique cybersecurity challenges. For example, the Space Applications sector relies heavily on satellite systems for critical services such as communication, navigation, and weather forecasting. A cybersecurity breach in this sector could lead to disruptions in these services, with serious consequences for both individuals and businesses.
In the Space Exploration sector, the cybersecurity of spacecraft and their systems is essential for the success of missions. A cybersecurity breach could lead to the loss of valuable scientific data or even the failure of a mission.
In the Space Transportation sector, cybersecurity threats could target launch vehicles and their payloads, leading to the loss of spacecraft and other hardware. Additionally, cyber-attacks on ground-based systems, such as launch pads and mission control centres, could disrupt operations.
Finally, the Space Manufacturing sector faces cybersecurity challenges related to the design, development, and production of space-related hardware and equipment. Intellectual property theft and sabotage are major concerns, as cyber-attacks could compromise the safety and reliability of these systems.
Given the high stakes involved in the space industry, it is crucial for all sectors to prioritise cybersecurity and invest in innovative solutions to mitigate these risks.
Cybersecurity Threats in the Space Domain
The space domain faces similar cybersecurity threats as other sectors, such as espionage, sabotage, and terrorism, but also unique challenges due to its environment and complexity. For example, space systems operate in a harsh and remote environment with limited resources, making it difficult to detect and respond to cyber-attacks. Moreover, space systems are highly integrated and interconnected, with multiple layers of hardware and software, making it challenging to secure the entire supply chain. Additionally, space systems rely on radio frequency communication and transmission, which can be intercepted or jammed by adversaries. Many satellites are operated by governments or militaries, which makes them attractive targets for state-sponsored cyber-attacks. Finally, the lack of standardisation and regulation in the space domain can hinder the adoption of cybersecurity best practices and increase the risks of vulnerabilities and exploits.
Current Efforts to Ensure Cybersecurity in the Space Domain
The space industry and space agencies are taking various measures to ensure cybersecurity in the space domain, such as encryption, network segmentation, access controls, and continuous monitoring. Space agencies and private companies are investing in a range of cybersecurity measures. Encryption is commonly used to protect sensitive data transmitted between satellites and ground stations. Network segmentation is also used to isolate different components of a space system and limit the potential impact of a cyber-attack.
International cooperation is also essential for improving space cybersecurity. The EU Space Situational Awareness (SSA) programme is an example of such cooperation. The SSA programme aims to improve the surveillance and tracking of objects in space, including space debris and potential threats such as asteroids or other objects that could collide with satellites. The programme also includes a cybersecurity component that aims to improve the resilience of space systems against cyber-attacks.
In addition to these measures, new technologies such as artificial intelligence and blockchain are also being explored as potential solutions to space cybersecurity challenges. For example, AI could be used to identify and respond to cyber-attacks in real-time, while blockchain could be used to create a secure and transparent record of satellite operations.
The NIS 2 directive of the EU on measures for a high common level of cybersecurity across the Union also sets out cybersecurity requirements for the space industry and other critical infrastructure sectors, such as risk management, incident reporting, and information sharing. Moreover, the new EU Space Strategy for Security and Defence highlights the importance of space cybersecurity as a key priority for the EU and outlines several actions to enhance the resilience and security of EU space assets and infrastructure.
Future Challenges and Opportunities in Space Cybersecurity
The emerging technologies in the space domain, such as small satellites, space tourism, and commercial space ventures, pose new cybersecurity challenges for the space industry. For example, the proliferation of small satellites and the lack of regulatory oversight can increase the risks of collisions, interference, and cyber-attacks. Similarly, the growing commercialisation of space activities and the involvement of non-state actors can challenge the traditional models of space governance and security. However, these developments also offer opportunities for the space industry to innovate and improve cybersecurity, such as the use of artificial intelligence and blockchain technology to enhance space. Key areas of evolvement to watch:
Small Satellites: The proliferation of small satellites, such as CubeSats and nano satellites, is driving down the cost of space missions and increasing access to space for a wider range of organisations. However, these smaller satellites often have limited onboard computing power and storage, which can make them vulnerable to cyber-attacks. Additionally, they are often launched in constellations, which creates a large attack surface and makes it difficult to monitor for anomalies. Ensuring cybersecurity for small satellites will require innovative solutions that can be deployed at scale and are tailored to the unique constraints of these platforms.
Commercial Space Ventures: With the rise of commercial space companies, such as SpaceX and Blue Origin, there will be new players entering the space domain with different priorities and risk profiles than traditional government space agencies. These companies may prioritise cost savings over security, which could result in increased vulnerability to cyber-attacks. It will be important for the industry as a whole to establish best practices for cybersecurity in commercial space ventures and to ensure that these companies are held to a high standard of security.
Emerging Technologies: As the space industry continues to innovate, new technologies will create both new opportunities and new cybersecurity challenges. For example, artificial intelligence and machine learning could be used to improve space situational awareness and detect anomalies in spacecraft behaviour, but they could also be used to automate cyber-attacks or create new attack vectors. If an AI system is compromised, it could make incorrect decisions or provide false information, which could have serious consequences. Similarly, blockchain technology could be used to secure space communications and data exchange by ensuring the integrity of satellite data and preventing unauthorised access to sensitive information, but it could also be vulnerable to attacks or exploitation. Ensuring cybersecurity in emerging technologies will require collaboration between the space industry and experts in cybersecurity and data privacy.
Global Cooperation: Ensuring cybersecurity in the space domain is not just a concern for individual countries or organisations, but a European and global challenge. Cyber-attacks on satellites or other space assets could have wide-ranging impacts on critical infrastructure and services, such as satellite navigation, weather forecasting, and telecommunications. Therefore, European and international cooperation will be essential to ensure that space cybersecurity measures are effective and that the global community is prepared to respond to threats.
The future of space cybersecurity will be shaped by a range of factors, from emerging technologies to new players in the industry and politics. However, with proactive collaboration and investment in innovative solutions, the space industry can mitigate the risks and seize the opportunities presented by these trends.
Conclusion
In conclusion, ensuring cybersecurity in the space domain is a complex and challenging task. The unique challenges of the space domain, such as the lack of standardisation and the complexity of space systems, make it difficult to implement effective cybersecurity measures. However, as the space industry continues to evolve, it is essential that cybersecurity is prioritised, and innovative solutions are developed to protect against cyber threats.
