Securing the final frontier: Digital twins, satellites and cybersecurity

Kevin Coggins

The United States and our allies are increasingly dependent on unfettered access to space. However, it has become abundantly clear that our space systems have significant cybersecurity vulnerabilities that our adversaries are eager to exploit.

Earlier this year, William Akoto wrote about the growing constellations of satellites operated by private industry, led by SpaceX, Blue Origin and others: “If hackers were to take control of these satellites, the consequences could be dire. On the mundane end of scale, hackers could simply shut satellites down, denying access to their services. Hackers could also jam or spoof the signals from satellites, creating havoc for critical infrastructure. This includes electric grids, water networks and transportation systems.”

Space Policy Directive 5, recently issued by the White House, notes that “cybersecurity principles and practices that apply to terrestrial systems also apply to space systems” and that we must integrate these principles and practices into every phase of the space system life cycle.

SPD-5 is charting the right course toward assuring our cybersecurity in the space domain. This article highlights the unique vulnerabilities of space systems and how innovative solutions like “digital twins” can help us protect systems in orbit today and design more secure ones for the future.

Cyberattacks on space systems — comprised of satellites, ground control stations, and user terminals (e.g., GPS receivers) — are appealing to nation-states, criminal groups, hackers and other bad actors. It's a tremendous opportunity to breach data and disrupt operations in a low-risk way with a low cost of execution. The different components that make up space systems each come with their own set of cyber vulnerabilities, the ground segment in particular.

Some space systems were built with speed to market rather than cybersecurity in mind. In contrast, for traditional defense-focused space systems, a slower design and development process has introduced vulnerabilities as well. Space systems operating today may have taken a full 20 years to go from paper to launch and lack the capabilities to recognize or respond to today's cyberthreats. Space systems are increasingly interconnected — a malicious attack can easily spread from a single point of vulnerability in a ground station to the satellites.

Cybersecurity in space systems has struggled to keep pace with the rapid evolution of threat actors and exploits. Given these challenges, how can organizations with space systems stay ahead of cyberthreats and protect their missions and users?

The older approach of paper-based assessments has significant limitations, like the inability to duplicate reactions to all possible scenarios. At the other end of the spectrum, full-scale replicas are expensive and time-consuming to build.

In the middle is the “digital twin” concept — a virtual mirror model that synchronizes a physical object with a cyber representation. With this approach, organizations can test a satellite in different scenarios to identify vulnerabilities and develop protection strategies, even before the satellite is built.

One specific project that demonstrated digital twins' strengths and capabilities: testing Air Force GPS space systems for vulnerabilities after the passage of Section 1647 of the 2016 National Defense Authorization Act.

Starting with a model-based system engineering review of thousands of pages of design documents, we built a digital replica of critical GPS Block IIR satellite components launched between 1987 and 2004 that ran on a single laptop with lightweight applications.

Our digital twin created the foundation for a flexible cyber test bed — a suite of scalable software applications to demonstrate and validate cyber vulnerabilities and protection strategies as the system is designed or modified. The test bed can connect with assets beyond the network to generate data, provide war-gaming support and explore attack scenarios.

We need this flexibility and functionality for future space system protection. The next generation of satellites will encounter more extreme service conditions and increased, simultaneous cyberattack vectors over longer periods of time. To respond to these challenges, these space systems will need increasingly complex designs, and with such complexity comes potentially greater vulnerability to cyberattacks and threats.

Digital twins and model-based system engineering approaches can strengthen security throughout the acquisition and sustainment phases. Use them to:

  • Develop system requirements and analyze design trades.
  • Create test scenarios for requirements clarification and reference systems.
  • Simulate threats, anomalies and impacts without risk to critical infrastructure.
  • Assess the impact of new threats or operational scenarios on an on-orbit system design.

What can space system acquisition professionals, developers and operators learn here? Digital twins offer an innovative approach that can streamline and strengthen the testing and design process of our space assets. They can also provide insights on as-built systems and enable the buydown of risks across the space system life cycle, enabling affordability across the entire system life cycle. Now is the time to leverage their capabilities, to ensure that the space infrastructure so vital to our security and American way of life has the protection it requires.

    BAE Offers Truck-Mounted Howitzer For Army Stryker Units

    Already fielded in Sweden — and mounted on a Volvo truck — BAE's 155 mm Archer will compete in a US Army “shoot off” early next year. SYDNEY J. FREEDBERG JR. WASHINGTON: The Army is seeking a self-propelled replacement for its venerable towed artillery pieces. The old ones can't keep up with mechanized Stryker units and lack armor protection. BAE Systems says its Archer armored howitzer is the quickest cannon on the draw — a life-or-death factor in fast-moving future combats. The US is experimenting intensely in how to speed the process from detecting a potential target to sending accurate target coordinates to a specific gun. Once Archer receives such target coordinates, it can come to a stop and open fire within 20 seconds, said Henrik Knape, a BAE exec based in Sweden, where the gun is already in service. Within two minutes from that first shot, Knape went on, the truck-mounted 155mm howitzer can fire another five to seven rounds, get back underway, and put 500 meters (a third of a mile) between itself and the location it fired from. That's a long enough distance in a short enough time that retaliatory fire from the enemy's artillery is probably going to miss. Even for an advanced adversary (pronounce that “Russia”), which uses specialized counter-battery radars to track the trajectory of incoming rounds and calculate the precise position of the unit firing them, it will take multiple minutes to bring its own guns or drones to bear. In US operations, the time from detecting a target to firing on it is typically “tens of minutes.” Experimental artificial-intelligence systems can cut that to tens of seconds, but those are years from being battle ready. Archer has other advantages as well, Knape and his US-based colleague Chris King told a small group of reporters: It's been in Swedish service since 2016, with the Defense Ministry asking Parliament to fund another 24 guns, so it's already extensively field-tested. It's armored against shrapnel and small arms, in case the enemy does get close. Its long barrel – 52 calibers, a third longer than the standard US howitzer – gives it extended range, comparable to the tracked ERCA howitzer entering service with US armored units in 2023. That gun is already qualified in US testing to fire precision-guided projectiles like Raytheon's Excalibur and BAE's own BONUS. And it's mounted on a six-wheel-drive, articulated Volvo chassis with enough cross-country mobility to keep up with the Army's 8×8 Strykers, which currently have only towed guns to accompany them.There are smaller wheeled artillery vehicles on the market than Archer, which doesn't fit on the standard C-130 turboprop transport, Knape and King acknowledged. (We check out a Humvee-mounted 105 mm cannon here).But none of them, they argue, has Archer's combination of firepower, protection, and quickness. The secret to that speed is automation, BAE says. While the US Army's current systems – both towed howitzers and the armored M109 Paladin – still rely largely on human muscle to manhandle heavy shells into the gun, Archer has a built-in autoloader. While well-trained human crews can actually fire faster than autoloaders for brief periods, the mechanical systems don't get tired or injured, and they allow for a much smaller gun crew. Archer can theoretically operate with a single soldier aboard, although it's designed for a crew of three – all of whom can stay inside the armored cabin while the weapon fires and reloads.https://breakingdefense.com/2020/10/bae-offers-truck-mounted-howitzer-for-army-stryker-units/
