  Modern vehicles become increasingly digitalized with advanced information
technology-based solutions like advanced driving assistance systems and
vehicle-to-x communications. These systems are complex and interconnected.
Rising complexity and increasing outside exposure has created a steadily rising
demand for more cyber-secure systems. Thus, also standardization bodies and
regulators issued standards and regulations to prescribe more secure
development processes. This security, however, also has to be validated and
verified. In order to keep pace with the need for more thorough, quicker and
comparable testing, today's generally manual testing processes have to be
structured and optimized. Based on existing and emerging standards for
cybersecurity engineering, this paper therefore outlines a structured testing
process for verifying and validating automotive cybersecurity, for which there
is no standardized method so far. Despite presenting a commonly structured
framework, the process is flexible in order to allow implementers to utilize
their own, accustomed toolsets.
