From Earth to Orbit: Understanding and Preventing Cyber Attacks on Space Systems

Space systems have become critical components of modern society, and their importance continues to grow as the world becomes increasingly reliant on technology. Space systems are used for communication, navigation, weather forecasting, and national defense, among other purposes. However, as space systems rely on computer networks and software, they are vulnerable to cyber attacks. Cyber attacks on space systems can have catastrophic consequences, including loss of critical data, disruption of communication, and even damage or destruction of space assets.

It is, therefore, crucial to understand the nature of cyber attacks on space systems and take preventive measures to safeguard these assets. Cyber attacks on space systems can come from various sources, including state-sponsored attacks, hackers, and insider threats. These attacks can exploit vulnerabilities in the software, hardware, and communication protocols used in space systems.

The expansion of the New Space economy, innovation in technologies, and the emergence of various private firms have contributed to the development of the space industry. However, this growth has also expanded the cyberattack surface of space systems, making them more susceptible to attacks. Attacks are becoming more sophisticated and affecting several components of the space system’s architecture, including ground segment, space segment, and communications.

Cyber threats to space systems can come from various sources, including state-sponsored attacks, hackers, and insider threats. Attackers can exploit vulnerabilities in the software, hardware, and communication protocols used in space systems. For instance, in 1998, hackers took control of the US-German ROSAT X-Ray satellite by hacking into computers at the Goddard Space Flight Center in Maryland. They instructed the satellite to aim its solar panels directly at the sun, which fried its batteries and rendered the satellite useless. The defunct satellite eventually crashed back to Earth in 2011. Hackers can also hold satellites for ransom, as happened in 1999 when hackers took control of the UK’s SkyNet satellites.

Preventing cyber attacks on space systems requires a multi-pronged approach that involves implementing robust cybersecurity measures, training employees, and promoting collaboration between the public and private sectors. Encryption, access control, and continuous monitoring of space systems are some of the cybersecurity measures that can be implemented to protect space systems from cyber attacks. Space system operators and employees must be trained to identify and respond to potential cyber threats actively. Governments and space agencies worldwide are recognizing the importance of cybersecurity in space systems and are taking steps to enhance the resilience of space systems against cyber threats.

For instance, the United States government has established the Space Information Sharing and Analysis Center (Space ISAC), a public-private partnership aimed at enhancing the resilience of space systems against cyber threats. Congress could work to adopt a comprehensive regulatory framework for the commercial space sector that mandates the reporting of all cyber breaches involving satellites. There also needs to be clarity on which space-based assets are deemed critical to prioritize cybersecurity efforts. Clear legal guidance on who bears responsibility for cyberattacks on satellites will also go a long way to ensure that the responsible parties take the necessary measures to secure these systems.

In order to address all space system stakeholders, several security principles for satellites and space assets are proposed to help reorient the sector toward designing, developing, building, and managing cyber secure systems. These security principles address both technical and policy issues.

Technical Issues:

  1. Secure system design

  2. Secure software

  3. Secure communication

  4. Secure supply chain

  5. Incident response and recovery

  6. Continuous monitoring and assessment

Policy Issues:

  1. Cybersecurity governance

  2. Cybersecurity standards and regulations

  3. Cybersecurity education and training

  4. Cybersecurity risk management

In conclusion, cyber attacks pose a significant threat to space systems, and it is essential to take proactive steps to prevent them. This includes implementing cybersecurity measures, training employees, and promoting collaboration between the public and private sectors. By doing so, we can ensure that space systems continue to play a vital role in our daily lives without being compromised by cyber threats.

In addition, the complex supply chain of these satellites and the multiple parties involved in their management means it’s often not clear who bears responsibility and liability for cyber breaches. Clear legal guidance on who bears responsibility for cyberattacks on satellites will also go a long way to ensuring that the responsible parties take the necessary measures to secure these systems.

 

Finally, it would be a profound mistake to wait for hackers to gain control of a commercial satellite and use it to threaten life, limb, and property before addressing this issue.
