The automotive industry is on the brink of a technological revolution, as vehicles increasingly rely on sophisticated electronic control units (ECUs) interconnected through Controller Area Network (CAN) protocols. While these advancements have brought unprecedented levels of efficiency and functionality, they have also exposed the sector to a growing threat landscape related to the security of CAN bus communication. This paper addresses this critical concern by presenting a comprehensive examination of automotive cybersecurity, with a focus on the vulnerability of CAN networks and the imperative to safeguard their electronic control units. The central thesis of this research revolves around the development and implementation of an innovative testing environment tailored for evaluating the susceptibility of CAN networks to common cyber-attacks.
