The National Academies Board on Human-Systems Integration (BOHSI) has organized this session. An initial presentation by the director of BOHSI will provide information on recent projects and updates. Then a panel will discuss the application of human-systems integration (HSI) to the issue of cyber security. Cyber security attempts to protect devices, networks, applications, and data from unintended or unauthorized access. A cyber security solution should not only focus on technology, but also the malevolent behaviors of those wanting to exploit system weaknesses, the cognitive processes required by cyber analysts, as well as the behavior of every day users who may open the door to vulnerability. The panel will therefore address issues related to the human decision process in both defensive and offensive cybersecurity operations. The panel will present future opportunities and will engage the audience in a discussion of these issues.
