    As aviation adopts new and increasingly complex operational paradigms, vehicle types, and technologies to broaden airspace capability and efficiency, maintaining a safe system will require recognition and timely mitigation of new safety issues as they emerge and before significant consequences occur. A shift toward a more predictive risk mitigation capability becomes critical to meet this challenge. In-time safety assurance comprises monitoring, assessment, and mitigation functions that proactively reduce risk in complex operational environments where the interplay of hazards may not be known (and therefore not accounted for) during design. These functions can also help to understand and predict emergent effects caused by the increased use of automation or autonomous functions that may exhibit unexpected non-deterministic behaviors. The envisioned monitoring and assessment functions can look for precursors, anomalies, and trends (PATs) by applying model-based and data-driven methods. Outputs would then drive downstream mitigation(s) if needed to reduce risk. These mitigations may be accomplished using traditional design revision processes or via operational (and sometimes automated) mechanisms. The latter refers to the in-time aspect of the system concept. This report comprises architecture and information requirements and considerations toward enabling such a capability within the domain of low altitude highly autonomous urban flight operations. This domain may span, for example, public-use surveillance missions flown by small unmanned aircraft (e.g., infrastructure inspection, facility management, emergency response, law enforcement, and/or security) to transportation missions flown by larger aircraft that may carry passengers or deliver products. Caveat: Any stated requirements in this report should be considered initial requirements that are intended to drive research and development (R&D). These initial requirements are likely to evolve based on R&D findings, refinement of operational concepts, industry advances, and new industry or regulatory policies or standards related to safety assurance

    Cybersecurity Vulnerability Analysis and Countermeasures of Commercial Aircraft Avionic Systems

    Nowadays, most commercial aircraft use systems with innovative technologies and unprecedented infrastructure of avionics applications which include cyber technologies. Airplane passengers are now using aviation cyber technologies when purchasing tickets, checking in at the airline counter, passing through airport security, and connecting to Wi-Fi and the embedded inflight entertainment system. Cyber technologies and connectivity expose aviation to a dangerous and costly world of cyber threats that pose a major challenge of an attack which makes the risks difficult to understand or to define. In addition, the opportunities for attacks continually grow as new services and systems are developed. This thesis looks at understanding these cybersecurity threats and countermeasures of avionics network systems, and their associated defense safety mechanisms and risk analysis will help to pave a secure path toward the increase of protection of our future aviation

    Cybersecurity is an important facilitator for essential aviation safety. The adoption rate for levels of cyber-security protocols at commercial airports is the focus of this research. Scope of this research is limited to cybersecurity maturity model capability norms covering fourteen domains. The paper presents primary data collected from several airport authorities. This survey-based study will be useful in identifying areas for improving operational procedures and developing strong cybersecurity governance at airports. This will allow airports to understand risks and respond proactively by adopting cybersecurity best practices and resilience measures. This study includes domestic, international, privately owned airports, airstrips, or aerodromes. This research found that level one of cyber-security maturity model is the most followed while proactive and advance levels i.e., level 4 and 5 are least adhered to. Most airports appear to have some resources allocated to cyber protection and resilience

    Building and Integrating an Information Security Trustworthiness Framework for Aviation Systems

    The aviation infrastructure is broadly composed of aircraft, air traffic control systems, airports and public airfields. Much attention has been given to physical security along the years this industry has been expanding; and now, in the new age of interconnection devices, a growing concern about cybersecurity has risen. The never-ending improvement of new digital technology has given birth to a new generation of electronic-enabled (e-enabled) aircraft that implement a remarkable amount of new technologies such as IP-enabled networks, COTS (commercial off-the- shelf) components, wireless connectivity, and global positioning systems (GPSs). For example, aircraft manufacturers are building wireless systems to reduce the amount of wiring within an aircraft. The general purpose of this is the reduction in weight that helps an aircraft achieve lower fuel consumption, but it can result into a security issue since these wireless systems are vulnerable to cybersecurity threats. Therefore, since the aviation infrastructure has taken advantages of the era of technology and is providing unprecedented global connectivity, there is a need for an in-depth study of the measures being taken to mitigate the security vulnerabilities that these e-enabled aircraft technologies introduce that may have not been considered in the traditional aircraft design

    The Federal Aviation Administration’s (FAA) Next Generation Air Transportation (NextGen) program is a long-term modernization and transformation of the current National Airspace System (NAS) into a more effective and coordinated decision-making system. NextGen provides a more reliable, secure, and dependable aviation capability for both users and operators ensuring more capacity, throughput, and safety. This research delineates a high-level Safety Risk Assessment (SRA) related to NextGen technologies, specifically Aircraft Communications Addressing and Reporting System (ACARS) as well as Aircraft Access to System Wide Information Management (SWIM) network (AAtS). Other communication mediums such as Mode-S or ADS-B transponder are also data exchange and broadcast capabilities in the aircraft can also be prone to lower level safety risks primarily because of an inability to ensure information security

    The paper discusses the possible impact of digital space on a human, as well as human-related directions in cyber-security analysis in the education: levels of cyber-security, social engineering role in cyber-security of education, “cognitive vaccination”. “A Human” is considered in general meaning, mainly as a learner. The analysis is provided on the basis of experience of hybrid war in Ukraine that have demonstrated the change of the target of military operations from military personnel and critical infrastructure to a human in general. Young people are the vulnerable group that can be the main goal of cognitive operations in long-term perspective, and they are the weakest link of the System.У статті обговорюється можливий вплив цифрового простору на людину, а також пов'язані з людиною напрямки кібербезпеки в освіті: рівні кібербезпеки, роль соціального інжинірингу в кібербезпеці освіти, «когнітивна вакцинація». «Людина» розглядається в загальному значенні, головним чином як та, що навчається. Аналіз надається на основі досвіду гібридної війни в Україні, яка продемонструвала зміну цілей військових операцій з військовослужбовців та критичної інфраструктури на людину загалом. Молодь - це вразлива група, яка може бути основною метою таких операцій в довгостроковій перспективі, і вони є найслабшою ланкою системи.В документе обсуждается возможное влияние цифрового пространства на человека, а также связанные с ним направления в анализе кибербезопасности в образовании: уровни кибербезопасности, роль социальной инженерии в кибербезопасности образования, «когнитивная вакцинация». «Человек» рассматривается в общем смысле, в основном как ученик. Анализ представлен на основе опыта гибридной войны в Украине, которая продемонстрировала изменение цели военных действий с военного персонала и критической инфраструктуры на человека в целом. Молодые люди являются уязвимой группой, которая может быть главной целью когнитивных операций в долгосрочной перспективе, и они являются самым слабым звеном Систем
