The cybersecurity toolkitcollections of digital tools, tutorials, tips, best practices, and other recommendationshas emerged as a popular approach for preventing and addressing cybersecurity threats and attacks. Often these toolkits are oriented toward vulnerable populations who have unique and pressing needs related to cybersecurity but may not have access to the resources of large governments, corporations, or other organizations. Many such tools are designed specifically for journalists, researchers, political activists, and certain minority groups such as refugees and LGBTQ youth. This project is concerned with studying this category of cybersecurity tools to inform the design and development of cybersecurity toolkits for both near-term and far-term futures. The project will adopt a mixed methodological approach rooted in human-computer interaction (HCI) and design.
