"They Keep Coming Back Like Zombies": Improving Software Updating Interfaces

Users often do not install security-related software updates, leaving their devices open to exploitation by attackers. We are beginning to understand what factors affect this software updating behavior but the question of how to improve current software updating interfaces however remains unan swered. In this paper, we begin tackling this question by studying software updating behaviors, designing alternative updating interfaces, and evaluating these designs. We describe a formative study of 30 users' software updating practices, describe the low fidelity prototype we developed to address the issues identified in formative work, and the evaluation of our prototype with 22 users. Our findings suggest that updates interrupt users, users lack sufficient information to decide whether or not to update, and vary in terms of how they want to be notified and provide consent for updates. Based on our study, we make four recommendations to improve desktop updating interfaces and outline socio-technical considerations around software updating that will ultimately affect end-user security.
