dc.description.abstractUsers receive a multitude of digital- and physical-security advice every day. Indeed, if we implemented all the security advice we received, we would never leave our houses or use the Internet. Instead, users selectively choose some advice to accept and some (most) to reject; however, it is unclear whether they are effectively prioritizing what is most important or most useful. If we can understand from where users take security advice and how they subsequently develop security behaviors, we can develop more effective security interventions. As a first step, we conducted 25 semi-structured interviews of security-sensitive (those users who deal with sensitive data or hold security clearances) and general users. These interviews resulted in several key findings: (1) users' main sources of digital-security advice include IT professionals, workplaces, and negative events, whether experienced personally or retold through TV; (2) users determine whether to accept digital-security advice based on the trustworthiness of the advice-source, as they feel inadequately able to evaluate the advice content; (3) users reject advice for many reasons, from believing that someone else is responsible for their security to finding that the advice contains too much marketing material or threatens their privacy; and (4) security-sensitive users differ from general users in a number of ways, including feeling that digital-security advice is more useful in their day-to-day lives and relying heavily on their workplace as a source of security information. These and our other findings inform a set of design recommendations for enhancing the efficacy of digital-security advice.en_US
