With the expansion across the aviation industry of connectivity and computing services, cybersecurity has become ever more important. Connecting people, processes and assets creates new vulnerabilities and multiple attack points—from flight-critical avionics to passenger inflight entertainment networks and airline backend operations. Information about systems, protocols and technologies such as software-defined radio are now readily available well beyond the industry. Demand for greater efficiency meanwhile continues to increase connectivity and accelerate computerization within aviation infrastructure, including aircraft.
Fortunately, ongoing efforts to protect aircraft, airlines and passengers from cybersecurity threats have been largely unaffected by the global pandemic, suggesting an opportunity for the industry to ramp up cybersafety programs and training amid the current slowdown. The comprehensive, coordinated nature of aviation cybersecurity initiatives means committees have long carried out their work primarily through virtual meetings, so those efforts are able to continue in full swing. With slowdowns taking place in other areas, the industry can address cybersafety at a more rapid pace.
The aviation industry and its stakeholders have been working hard to tackle cybersecurity challenges comprehensively—from the supply chain and the maintenance of aircraft to operations. Such efforts remain essential so that cyberthreats affecting safety can be mitigated before they materialize, whether that happens during flight through physical access to a bus, by interfering with equipment through Wi-Fi or remotely disrupting operations.
The need to weigh cyberthreats according to their safety impact, a practice referred to as “cybersafety,” requires a different perspective than that of IT cybersecurity. Cybersafety differs from traditional IT cybersecurity because of the need for safety certification, which relies on guaranteeing a system's behavior, or “determinism.” This unique characteristic of aviation cybersafety means that solutions widely used across traditional computing systems may pose serious certification challenges. Imagine rolling out security patches for every avionics component on a commercial aircraft.
Tackling cybersafety challenges requires a coordinated, comprehensive, global effort. Multiple agencies are cooperating to establish much-needed standards. For example, the U.S. FAA and the European Union Aviation Safety Agency have been working with the RTCA and the European Organization for Civil Aviation Equipment to set harmonized cybersecurity standards.
Efforts to secure the aviation ecosystem also include dedicated committees such as the FAA's Aviation Rulemaking Advisory Committee Aircraft System Information Security/Protection working group. Similarly, the Aerospace Industries Association has established the Civil Aviation Cybersecurity Subcommittee.
In the U.S., the Aviation Cyber Initiative (ACI) is led by the Defense Department, Department of Homeland Security and FAA. The ACI includes experts representing government, defense, industry and academia who collaborate to tackle aviation cybersecurity threats. The Aviation Information Sharing and Analysis Center shares global threat intelligence among aviation companies.
Globally, the International Civil Aviation Organization (ICAO) leads this work. Its Trust Framework Study Group (TFSG) includes experts from the FAA, EASA, commercial industry and academia and has established three important working groups.
Academic institutions play a critical role in advancing cybersecurity research and training, too. Embry-Riddle Aeronautical University, for example, develops engineering solutions and provides degree, certification and training programs in aviation cybsersecurity. Faculty researchers contribute expertise to cyberdefense and preparedness efforts by serving on national and international committees and working groups and by organizing the annual Aero-Cybersecurity Symposium.
Aviation's impeccable safety culture positions it well to combat and defeat cybersafety risks. In the years ahead, the industry will need to invest in expanded education and training as well as research to secure high-assurance systems that can be updated with minimal impact on certification.
Computerization and Cyberphysical Systems
As computing becomes ever more affordable, functions that were traditionally implemented through hardware are now being realized through software, and inclusion of software has supported increased customization. Cyberphysical systems are designed to perform a set of functions with limited impact on the physical environment, such as temperature control, welding and parts assembly. One feature of cyberphysical systems is a failsafe property that involves shutting down—an approach that is clearly not desirable midflight.
Connectivity
Inexpensive and ubiquitously available computing, combined with advancements in networking, have accelerated the networking of devices. The Internet of Things concept does not require any form of certification or service-quality assurance, let alone any safety requirement or oversight. Rather than leveraging the Internet of Things, the aviation industry might consider using “networked wings” to underscore its safety commitment.

It appears that the new drone will come with an upgraded, or perhaps new, advanced air-to-air missile. by Kris Osborn The prospect of new drone-fired air-to-air weapons, such as those being introduced in DARPA's LongShot effort, raise impactful tactical questions regarding the nature of air warfare moving into future decades. The DARPA program is invested in engineering a new kind of aerial attack drone configured such that it can integrate a new generation of air-to-air weapons potentially changing or at least impacting existing aerial warfare paradigms. The Pentagon's DARPA just awarded LongShot development deals to Northrop Grumman, Lockheed and General Atomics to explore concepts, computer modeling and design options for a new air-attack platform. “Current air superiority concepts rely on advanced manned fighter aircraft to provide a penetrating counter air capability to effectively deliver weapons. It is envisioned that LongShot will increase the survivability of manned platforms by allowing them to be at standoff ranges far away from enemy threats, while an air-launched LongShot UAV efficiently closes the gap to take more effective missile shots,” DARPA writes in a statement on the program. What kinds of technologies and air-attack systems are likely to characterize future warfare in the skies? Clearly the intent of the DARPA program, which is early on and primarily in a conceptual phase, is to break existing technical barriers and architect weapons which advance the attack envelope well beyond simply upgrading existing weapons. This sets the bar quite high, given that the current state of upgraded air-to-air weapons is increasingly more advanced. The AIM-9X, for example, has been upgraded to accommodate what's called “off-boresight” targeting wherein a missile can engage a target to the side or even behind the aircraft it launches from. Off boresight capable AIM-9X missiles are now arming F-35s, bringing a new ability to fire course-changing air-to-air weapons at angles beyond direct line-of-sight. Weapons upgrades to the F-22 as well, brought to fruition through a Lockheed software upgrade called 3.2b, brings new upgrades to the AIM-9X and AIM-120D. Raytheon data explains that a Block 2 AIM-9X variant also adds a redesigned fuze, new datalink to support beyond visual range engagements, improved electronics and a digital ignition safety device. Another part of the weapons upgrade includes engineering the F-22 to fire the AIM-120D, a beyond visual range Advanced Medium-Range Air-to-Air Missile (AMRAAM), designed for all weather day-and-night attacks. It is a “fire and forget” missile with active transmit radar guidance, Raytheon data states. The AIM-120D is built with upgrades to previous AMRAAM missiles by increasing attack range, improving seeker guidance GPS navigation, inertial measurement units and a two-way data link, Raytheon statements explain. Air-to-Air weapons are also being upgraded with new “countermeasures” to, among other things, enable guidance systems to stay locked on target even in a “jamming” environment. For example, adversaries are increasingly engineering electronic warfare weapons intended to find and “jam” radio frequency or infrared targeting technologies used in air-to-air weapons. Technical efforts to “counter” the countermeasures with frequency-hopping adaptations can enable electronically guided weapons to sustain a precision trajectory despite enemy jamming attempts. These kinds of innovations might, at least initially, be providing a technical baseline from which new weapons can be envisioned, developed and ultimately engineered. The new air-to-air weapons intended for LongShot will most likely not only be much longer range but also operate with hardened guidance systems, flexible flight trajectories, advanced countermeasures, a wider range of fuze options and newer kinds of explosives as well.
