Cybersecurity Attacks on Software Logic and Error Handling Within ADS-B Implementations: Systematic Testing of Resilience and Countermeasures
2022
Automatic Dependent Surveillance-Broadcast (ADS-B) is a cornerstone of the next-generation digital sky and is now mandated in several countries. However, there have been many reports of serious security vulnerabilities in the ADS-B architecture. In this paper, we demonstrate and evaluate the impact of multiple cyberattacks on ADS-B via remote radio frequency links that affected various network, processing, and display subsystems used within the ADS-B ecosystem. Overall we implemented and tested 12 cyberattacks on ADS-B in a controlled environment, out of which 5 attacks were presented or implemented for the first time. For all these attacks, we developed a unique testbed that consisted of 1…
Understanding Crowdturfing : The Different Ethical Logics Behind the Clandestine Industry of Deception
2017
Crowdturfing, the dark side and usually unnoticed face of crowdsourcing, represents a form of cyber-deception in which workers are paid to express a false digital impression. While such behavior may not be punishable under the jurisdiction of formal law, its consequences are destructive to the cohesion and trustworthiness of online information. The conceptual work at hand examines the current literature on the topic, and lays the foundation for a theoretical framework that explains crowdturfing behavior. We discuss crowdturfing through three ethical normative approaches: traditional philosophical ethics, business ethics, and codified rules. We apply these lenses to an illustrative example o…
The emergence of liminal cyberspace : challenges for the ontological work in cybersecurity
2022
This philosophy-oriented paper examines cybersecurity and its ontological work in relation to spaces which are created by conventional perimeter security model and Zero Trust model. We argue that security works by a code of inclusion and exclusion, e.g., an individual user seeking access is either included or excluded in relation to the system. Therefore, cybersecurity divides the space through employing the code of inclusion/exclusion which directly affects the agency of users. We examine how the growing complexity of network environment makes information and cybersecurity to struggle with the simplicity of the inclusion/exclusion code. The simplified bifurcation is held by maintaining a s…
