Additional Observations on Foundational Cybersecurity Research: Improving Science, Engineering, and Institutions: An Annex: Unclassified Abbreviated Version of a Classified Report: “At the request of the Special Cyber Operations Research and Engineering (SCORE) Interagency Working Group and sponsored with assistance from the National Science Foundation and from the Office of the Director of National Intelligence, the National Academies of Sciences, Engineering, and Medicine appointed an expert committee to explore future research goals and directions for cybersecurity. The committee for this multi-phased sequential study considered future research goals and directions for foundational science in cybersecurity, and included relevant efforts in economics and behavioral science as well as more “traditional” cybersecurity topics. It considered major challenge problems, explored proposed new directions, identified gaps in the current portfolio, considered the complementary roles of research in unclassified and classified settings, and considered how foundational work in an unclassified setting can be translated to meet national security objectives. This abbreviated annex provides background information on the full classified annex resulting from the study.”
