As automobiles advance in connectivity, ADAS and EV Technologies. They Have become increasingly susceptible to external cyber-attacks because of the privilege in which vehicles had to connect with the outside world through various wireless and physical mediums.  Such threats pose a grave risk to both passenger safety and public security. However, the existing protocols and architectures need to be revised to address the distinct cybersecurity complexities inherent in automotive engineering, which include factors like safety, extended product lifecycles, and the integration of embedded controllers. Consequently, there is an urgent need to establish comprehensive and standardized guidelines for enhancing automotive security.
