For many years, automotive software was developed with the thought that the vehicle network and electronic control units (ECUs) were not exposed to or of interest to malicious hackers. Consequently, software developers and cybersecurity engineers had mismatched views and goals when projects began to include cybersecurity requirements.

Customers are becoming more aware that security is a buying concern and are looking for indications of safer products rather than just exercising brand loyalty. Manufacturers must implement more stringent security management where it is not well standardized or even established at all.
