Breakthroughs in testing and certification in cybersecurity: research gaps and open problems

Software and hardware systems are becoming increasingly complex and interconnected, making their testing and certification more challenging, considering cybersecurity aspects. The trustworthiness, security, and quality of these systems call for innovative approaches to testing and certifications. This paper provides an overview of some of the most promising research directions in software and hardware testing and certification in the cybersecurity area. It outlines some of the critical challenges and opportunities for future research. We discuss each approach's potential benefits and challenges, highlight some key research questions to be addressed in each area, and investigate how they can be used to promote "Full Quality - positive-sum, not zero-sum" in developing software and hardware systems.
