The Urgency of Safeguarding Space: Revamping Cybersecurity Amid Growing Satellite Reliance

Threats Growing reliance on satellites requires new approach to cybersecurity in space, expert says

The Importance of Space Systems in Critical Infrastructure

As critical infrastructure organizations increasingly rely on satellite communication, experts emphasize the need for enhanced cybersecurity measures in space systems. During a summit focused on space innovation, Sam Visner, a tech fellow at the Aerospace Corp., highlighted the significance of space systems in various sectors, such as finance, energy, transportation, healthcare, and agriculture. He noted that agriculture, for example, heavily relies on space systems for navigation and precision farming. Previously, space systems operated independently with their own command and control systems, making them relatively secure. However, with the convergence of cyberspace and space, these systems are now connected to global telecommunications and information technology infrastructure, leaving them vulnerable to cyberattacks.

Satellite Internet Service Targeted in Cyberattack

The cyberattack on Viasat, a leading American satellite internet service provider in Europe, illustrates the growing urgency to address space system cybersecurity. The incident has prompted cybersecurity officials in the U.S. and abroad to focus on safeguarding space systems. It also prompted the Cyberspace Solarium Commission to advocate for the designation of the space sector as critical infrastructure. This designation would allocate additional attention and resources to protect critical space systems.

The Challenges of Privatization and Supply Chain Security

As the space sector becomes increasingly privatized, concerns about supply chain security have emerged. Sam Visner specifically highlighted the lack of insight into the software supply chain in space systems. Supply chain attacks pose significant risks as malicious actors could compromise the integrity of software used in space systems, leading to potentially devastating consequences. To address this concern, an international group of experts has initiated efforts to implement security-by-design into new space systems through the Institute of Electrical and Electronics Engineers working group.

Analysis and Commentary

The increasing reliance on satellite networks across critical sectors brings to light crucial security vulnerabilities that need urgent attention. While space systems were traditionally standalone and perceived as secure, the growing interconnectedness with global telecommunications and information technology infrastructure has exposed them to cyber threats. This intersection of cyberspace and space necessitates a comprehensive and proactive approach to safeguarding space systems.

The designation of the space sector as critical infrastructure is a critical step in addressing the cybersecurity challenges in this domain. By recognizing the importance of space systems in various sectors, governments and policymakers can allocate resources and implement regulatory measures to enhance their security. This designation would also facilitate collaboration between public and private entities in developing robust cybersecurity frameworks to protect critical space systems.

Furthermore, as the privatization of the space sector progresses, it is essential to prioritize supply chain security. The lack of visibility into the software supply chain in space systems poses a significant vulnerability. Implementing security-by-design principles and conducting thorough supply chain risk assessments are essential to mitigate the risks of supply chain attacks. Collaboration between industry stakeholders, government agencies, and international organizations can drive the development of secure and resilient space systems.

Advice for Space System Cybersecurity

Given the increasing reliance on space systems, organizations should prioritize the following cybersecurity measures:

1. Robust Network Security:

Implement comprehensive network security solutions that protect space system infrastructure from unauthorized access, malware, and other cyber threats. This includes deploying firewalls, intrusion detection and prevention systems, and strong access controls.

2. Encryption and Secure Communications:

Ensure that all communications within space systems are encrypted to protect sensitive data from interception and tampering. Employing secure encryption algorithms and protocols is essential to maintain the confidentiality and integrity of communications.

3. Regular Vulnerability Assessments:

Conduct regular vulnerability assessments and penetration testing to identify and remediate potential weaknesses in space system networks and applications. This proactive approach helps uncover vulnerabilities before malicious actors exploit them.

4. Supply Chain Security:

Establish robust supply chain security measures by thoroughly vetting software and hardware components for space systems. Work closely with trusted suppliers and implement rigorous security checks to ensure the integrity of the supply chain.

5. Incident Response and Recovery Planning:

Develop comprehensive incident response plans that outline the steps to be taken in the event of a cyber incident. This includes identifying incident response teams, conducting tabletop exercises, and regularly reviewing and updating response plans.

Overall, the increasing reliance on satellite networks necessitates a proactive and collaborative approach to space system cybersecurity. Governments, organizations, and industry stakeholders must come together to prioritize the security of critical space systems. This requires robust network security measures, supply chain security considerations, and effective incident response planning. By embracing these recommendations, we can mitigate the risks posed by cyber threats in the evolving space landscape.
