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.

  • Lockheed Martin is Waging War on Boeing’s F-15EX

    Lockheed Martin is Waging War on Boeing’s F-15EX

    BY MARCUS WEISGERBER The F-35 makers sees the Pentagon's plans to buy new F-15s for the first time in 19 years as a threat. The F-35 Joint Strike Fighter has reportedly been racking up kills against older warplanes during U.S. military drills in Nevada — even the F-15, whose record in real combat is a flawless 104 to zero. Now the two jets are heading into a fierce dogfight, one that doesn't involve missiles or guns. The battle between Lockheed Martin's F-35 and Boeing's F-15EX is being fought by lobbyists in and around Congress, which is beginning to review the Pentagon's fiscal 2020 budget request. Tens of billions of dollars are up for grabs over the coming decade. This week, Pentagon officials proposed buying new F-15s for the first time since 2001, even though top Air Force officials have said as recently as two weeks ago that they didn't necessarily want the the planes. For nearly two decades, Air Force officials have argued against buying so-called fourth-generation planes, preferring for stealthier fifth-generation planes with newer technology. The proposed F-15 purchase is rather small: eight jets in 2020 and a total of 80 through 2024. By comparison, the Pentagon wants to buy 78 F-35s in 2020, with 48 going to the Air Force. SUBSCRIBE Receive daily email updates: Subscribe to the Defense One daily. Be the first to receive updates. But Pentagon budget documents also signal that the Air Force could buy hundreds of F-15s over the next decade. A tranche of 144 planes would “initially refresh” squadrons that fly Cold War-era F-15C Eagles designed for air-to-air combat. And the plane has the “potential to refresh the remainder of the F-15C/D fleet and the F-15E fleet.” In all, that's more than 400 planes. That was enough to draw a full-court press from Lockheed. One day after that announcement, company officials began circulating a three-page white paper detailing the “F-35's decisive edge” over unnamed fourth-generation warplanes. Defense One reviewed the white paper. Lockheed's arguments boil down to bang-for-the-buck: The F-35 will cost about the same or less than the F-15 soon (the long-criticized price has in fact been coming down), its operating costs will be less than the F-15's within six years, and it can fly a more diverse set of missions. Boeing's argument: The F-35 was never intended to replace the air-to-air F-15C — but the F-15EXcould do so while expanding those squadrons' capabilities. Pilots would not need to extensive training to fly the jet, which could carry heavy loads of weapons, plus Eagle bases would not need major infrastructure upgrades. And the new F-15EX is multirole, similar to the F-15E Strike Eagle, meaning that it could strike targets in the air, on the ground or at sea. Boeing has been pitching new F-15s to the Air Force on and off for more than a decade, most recently offering a similar version of the plane it builds for Saudi Arabia and Qatar. The latest effort started to pick up steam last summer. The idea was embraced within parts of the Air Force, but not by top Air Force leaders. Air Force Secretary Heather Wilson acknowledged on Feb. 28 that the planes were not in the service's initial budget plans. But analysis by the Joint Staff and Pentagon Cost Assessment and Program Evaluation Office “on the kinds of capabilities that we require in the aviation realm” led officials to recommend buying the F-15EX, a senior defense official said. Elaine McCusker, the Pentagon deputy comptroller, said Tuesday that former Defense Secretary Jim Mattis made the decision to include the F-15EX in the Defense Department's budget request. “The F-35 remains a critical program for the joint force as we look to the future and the kinds of capabilities we require,” Lt. Gen. Anthony Ierardi, director of force structure, resources and assessment on the Joint Staff, said Tuesday. “The F-15EX provides additional capacity and readiness, especially in the near years to mid years, as we look at the threats and the kinds of combat potential that we needed to bring to bear.” Whether Congress agrees with that rationale is yet to be seen. In February, five Republican senators — all with ties to Lockheed F-35 manufacturing work or F-35 bases — sent a letter to President Trump in opposition of the F-15EX. “We are extremely concerned that, over the last few years, the DoD has underfunded the F-35 Program and relied on Congress to fund increases in production, sustainment, and modernization,” they group led by Sen. John Cornyn, R-Texas, wrote. “In order to meet the overmatch and lethality goals laid out in the National Security Strategy, the DoD needs to make these investments in the F-35 to affordably deliver and operate this fifth-generation fighter fleet. The F-35 is the most affordable, lethal, and survivable air dominance fighter, and now is the time to double down on the program.” The 2020 budget request includes $11.2 billion to buy 78 F-35s — 48, which would be Air Force jets. That money would also go toward improving jets already built. Lawmakers have routinely added F-35s to the Pentagon's request. For instance, last year they added 16 planes to the 77 requested by the Defense Department. The 2020 budget request includes $1.1 billion for the eight F-15EX jets. Some of that money would go toward standing up the production line. About a month after Bloomberg first reported in December that eight F-15EX jets would be in the budget request, Marillyn Hewson, Lockheed's CEO, said Pentagon leaders told her that F-15 buys would not be at the expense of the F-35. “The combat proven F-35 is the National Defense Strategy in action and the program continues to see strong support throughout the Pentagon, the U.S. Services, Congress and the White House,” the company said in an emailed statement. Pentagon officials have been insisted that any F-15EX buys would not eat into planned F-35 buys. In all, the Pentagon plans to buy a total 2,443 jets over the coming decades. “If Congress changes that to all F-35s, they'll be all F-35s, we understand that,” Maj. Gen. David Krumm, director of strategic plans in the office of the deputy chief of staff for strategic plans and requirements at the Pentagon, said Thursday at the Mitchell Institute. “But based upon the resources we have and the ownership costs of the platforms, we think that this is the best way that we can present the nation's Air Force and the best way we can get to a capabilities and capacities that we have. “If we have more resources, I think we need to have a conversation about what it is we go for,” he said. “But based upon the resources that we have, we think that this is the right way to go.” https://www.defenseone.com/business/2019/03/lockheed-martin-waging-war-boeings-f-15ex/155598

    Thales integrated sonar suite selected for Spanish Navys New Multi-Mission Frigates

    November 12, 2019 - The General Directorate for Armament and Material (DGAM) and the naval shipyard Navantia have selected Thales technologies for the Spanish Navy's five new multi-mission frigates. The vessels' anti-submarine warfare (ASW) capability, based on two world-class sonars, the CAPTAS 4 Compact and the BlueMaster, and the BlueScan digital acoustic system, will be integrated through Navantia Combat Management System SCOMBA F110 and will enable the service to conduct maritime surveillance, search and protection missions in any theatre of operations. To protect their maritime territory and security interests around the world, States need to counter all types of threats in any environment or theatre of operations. Naval forces need reliable, high-performance systems to assert national sovereignty and accomplish their ASW missions with optimum effect. The choice of Thales technologies, which have been extensively proven in service with navies around the world, provides the highest levels of protection available today. BlueScan is a collaborative ASW solution that processes significantly higher volumes of sonar data from various different platforms to provide the operator with a complete overview of the acoustic situation in real time. The solution leverages Big Data analytics and artificial intelligence technologies to bring naval forces a tactical advantage. Under this contract, key underwater acoustics technology will be transferred to Spanish industry, in particular for the supply of the TUUM-6 digital underwater communication system and acoustic arrays. “After two years of talks with the Spanish Navy and Navantia about this contract to equip five F110 frigates, we welcome Spain's decision to join other NATO countries (the United Kingdom, France, Italy, Norway) and Australia in placing their trust in Thales for their anti-submarine warfare (ASW) capabilities. To help their naval forces conduct their missions in today's heightened underwater threat environment, Thales has invested for many years in Australia, France and the United Kingdom to develop a unique set of digital sonar data processing and analytics technologies. Given the complexity of the underwater environment and the level of sophistication of the adversary, digitalisation and data fusion techniques are the only effective way to counter undersea threats in the 21st century. With our Spanish partners, and with Navantia in particular, we are very pleased to have the opportunity to strengthen our cooperation on this programme, in which local industry will play a significant role in producing, integrating and maintaining the systems alongside the Spanish Navy." Alexis Morel, Vice President, Underwater Systems, Thales • Thales sonars and acoustic systems will provide the Spanish Navy's five F110 frigates with a latest-generation anti-submarine warfare (ASW) capability. • The key components of the integrated suite are the BlueMaster (UMS 4110) and CAPTAS 4 Compact sonars, the TUUM-6 underwater communication system, and the BlueScan digital acoustic system already in service with other European navies. • Spanish industry partners will supply some of the high-tech equipment under a decisive transfer of technology programme put in place by Thales.

    More than meets the eye: Army selects next-gen camouflage system

    By: Kyle Rempfer The Army has finally selected a company to provide it with the next generation of ultra light-weight, general-purpose camouflage. The Army's Ultra-Light Camouflage Netting System, or ULCANS, will be an all-weather, state-of-the-art signature concealment system that provides multi-spectral protection for troops and equipment. The program aims to replace the legacy woodland and desert camouflage variants developed in the 1990s, and will be developed in light and dark woodland, snow and alpine, desert, and urban variants. The Army hopes ULCANS will better conceal the signatures of troops and equipment from high-end sensor threats on the battlefield. The contract to produce the next-generation camouflage was awarded to Fibrotex USA Inc., according to a company statement provided to Army Times. The contract is a 10-year, indefinite delivery and indefinite quantity award, with a total value of $480 million. Fibrotex is expected to begin full-rate production in early 2019, according to the company. ULCANS is the result of nearly two years of testing, trials and data collection conducted by the U.S. Army's Natick Soldier Systems Center in Massachusetts. Natick tested camouflage technologies from major global manufacturers against the Army's most advanced battlefield surveillance sensors. Many of the technologies underpinning ULCANS are based on developments by Fibrotex's Israel-based parent company over the last two decades, but have been specially modified for the U.S. Department of Defense. The Fibrotex system will provide multi-spectral camouflage, which conceals objects from detection across several portions of the electromagnetic spectrum at the same time. Traditional military camouflage simply hides an object in the visible spectrum, but the multi-spectral design obscures detection in the infrared, thermal and radar spectrum as well. “Today more than ever, military forces and opposition groups are using night vision sensors and thermal devices against our troops, but by using Fibrotex's camouflage, concealment and deception solutions, we make them undetectable again, allowing them to continue keeping us safe," said Eyal Malleron, CEO of Fibrotex USA. Fibrotex will also deliver the ULCANS material in reversible designs — allowing for the first time a different pattern and capability on each side, enabling soldiers, vehicles and systems to disappear into light or dark woodland, snow or alpine and desert or urban environments in any operational theater. “We have more than 50 years of experience, with thousands of hours in the field and a deep understanding of conventional and asymmetric warfare," Malleron said. "The U.S. Army tested our best camouflage solutions, and the camouflage repeatedly demonstrated the ability to defeat all sensors known to be operating in the battlefield and throughout the electromagnetic spectrum.” ULCANS will also be manufactured stateside, in a new state-of-the-art facility in McCreary County, Kentucky, creating hundreds of new skilled American jobs over the next decade, according to Fibrotex. “I firmly believe we have the best workforce in the country, and that their hard work and dedication has earned these new jobs, helping deliver a vital new military contract from McCreary County," Rep. Hal Rogers, R-Ky., said in a press statement. "I take great pride in knowing that our people are crafting these products to keep our warfighters and allies safe, giving them an edge on the battlefield.” The new facility is being established next to Outdoor Venture Corporation, which is a strategic partner to Fibrotex USA and already designs modular personnel tents and command post tents for the Army. https://www.armytimes.com/news/your-military/2018/11/07/more-than-meets-the-eye-army-selects-next-gen-camouflage-system
