HSF is the Human and Societal Factors research group (RG) of the KASTEL Security Research Labs. The RG "Human and Societal Factors" focuses on answering research questions in the area of human- and law-aligned security and privacy by design. Researchers entail security and privacy measures specifically developed from scratch considering security, privacy, usability and legal aspects. Thereby, the research efforts currently cover four research areas and one cross-cutting topic and have established collaborations with researchers from other RGs and from all three labs.
