Thomas Baumer presented the research paper "Digital Nudges for Access Reviews: Guiding Deciders to Revoke Excessive Access" at the Twentieth Symposium on Usable Privacy and Security (SOUPS 2024, https://www.usenix.org/conference/soups2024 (externer Link, ?ffnet neues Fenster)) in Philadelphia, PA, USA. The research team includes his coauthors, Tobias Reittinger, Sascha Kern, and Günther Pernul. Together, they investigate the effects of digital nudges on access reviews by conducting expert interviews and a user study on choice defaults. While the paper covers many details, you can watch a recording of the talk on YouTube, summarizing the key results: https://www.youtube.com/watch?v=_DaQZUzrk3U (externer Link, ?ffnet neues Fenster).
