Abstract: With the demand for advanced functionality such as autonomous driving, the complexity and connectivity of modern vehicles have faced an overwhelming expansion in recent years. Although the numerous interfaces pave the way for a better user experience, recent research has demonstrated that they can also serve as an attack surface for cybercriminals. Therefore, researchers have been challenged to develop a wide variety of security solutions aiming to solve specific issues.In this paper, we substantiate the need for a holistic security solution for vehicular networks. Specifically, we observe that current state-of-the-art security solutions are often subject to layer-specific issues. To mitigate this problem, the need arises to develop solutions working across all the layers of the network stack.
