Learning, Sharing, and Exploring with NIST’s New Human-Centered Cybersecurity Community of Interest

Human-centered cybersecurity (also known as ‘usable security’) involves the social, organizational, and technological influences on people’s understanding of and interactions with cybersecurity. By taking a human-centered cybersecurity (HCC) approach, we can both improve people’s cybersecurity experiences and achieve better cybersecurity outcomes, which is so important in today’s digitally interconnected world. At NIST, we understand the…
