Abstract: Connected vehicles (CVs) represent a major technological advancement in the transportation sector, offering enhanced functionality, safety features, and real-time data communication. With the integration of Vehicle-to-Everything (V2X) technologies—including Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Cloud (V2C) systems—automobiles have transitioned into complex cyber-physical systems. However, this increased connectivity has exponentially expanded the attack surface, rendering vehicles vulnerable to numerous cybersecurity threats. Remote hijacking of vehicles, data breaches, denial of service attacks, and manipulation of vehicular control systems have been demonstrated in various research and real-world incidents. Such vulnerabilities pose significant risks not only to driver and passenger safety but also to broader public infrastructure.
This paper investigates the cybersecurity threats facing connected vehicles, analyzing potential attack vectors, risk impacts, and current mitigation approaches. Utilizing a comprehensive methodology involving threat modeling through the STRIDE framework, risk prioritization using a modified DREAD analysis, and case study evaluation, key security challenges are systematically identified. A detailed literature review emphasizes recent advances in automotive cybersecurity, including machine learning-based intrusion detection systems and blockchain solutions for secure communications. Results indicate that while advancements in secure communication protocols and in-vehicle network segmentation offer partial defenses, connected vehicles remain substantially exposed to evolving cyber threats.
Discussion of the findings reveals critical gaps in current defense strategies, underscoring the need for security-by-design practices, continuous monitoring, and a life-cycle security management approach. Standardization efforts by international bodies, though promising, are insufficient without rigorous industry adoption and frequent updates. The paper concludes by proposing future directions for research and policy, highlighting the importance of proactive and adaptive cybersecurity measures to ensure the safety, privacy, and reliability of connected vehicular ecosystems.
By addressing cybersecurity risks comprehensively, stakeholders can facilitate the safe evolution of connected vehicles, balancing innovation with robust protection measures to safeguard individuals and societies at large.
