The National Cyber Security Research Agenda (NCSRA-III) describes cybersecurity research challenges around five pillars, which together support cybersecurity research and development in the Netherlands. These pillars are: Design, Defense, Attacks, Governance and Privacy. Previous agendas were more disciplinary in design. With the now chosen division into pillars, scientific disciplines come together. They provide direction to the research and enable interdisciplinary collaboration. For example, each pillar requires contributions from computer science, technology, social sciences and the humanities. The goal is to contribute to the cybersecurity of various top sectors and NWA routes with the implementation of a single national cybersecurity research agenda.
