Cyber-Physical Impact Analysis of Security Breaches in Smart Vehicles

Abstract

Smart vehicles have evolved into interconnected cyber physical systems that integrate advanced sensing, embedded computation and continuous wireless connectivity. These features enhance safety and efficiency but also increase the attack surface and leave vehicles at substantial risk of cybersecurity attacks. In this paper, a theoretical and analytical assessment of security breaches in smart vehicles has been done by focusing on architectural weaknesses and their technical, operational and societal consequences. Furthermore, this paper investigates the vulnerabilities of in-vehicle networks, perception sensors and external communication interfaces based on the existing literature and documented incidents. The results shows that cyber intrusions are capable of undermining vehicle control, compromising safety features, revealing sensitive user data, and disrupting mobility services on a large scale. The analysis shows that security breaches is not only a digital form of compromise but also may have a physical safety risks and loss of public trust. The paper summarizing the industrial challenges and the future research directions enhance resilience and accountability in connected and autonomous vehicle ecosystems.
