Smart Home Personal Assistants (SPA) are an emerging innovation that is changing the way home users interact with technology, but they are exposed to various risks. The article provides an in-depth review of the security and privacy issues of SPA, categorizing important attack vectors and discussing open research challenges to address these issues in the future.
Smart Home Personal Assistants (SPA) are an emerging innovation that is changing the means by which home users interact with technology. However, several elements expose these systems to various risks: (i) the open nature of the voice channel they use, (ii) the complexity of their architecture, (iii) the Al features they rely on, and (iv) their use of a wide range of underlying technologies. This article presents an in-depth review of SPA's security and privacy issues, categorizing the most important attack vectors and their countermeasures. Based on this, we discuss open research challenges that can help steer the community to tackle and address current security and privacy issues in SPA. One of our key findings is that even though the attack surface of SPA is conspicuously broad and there has been a significant amount of recent research efforts in this area, research has so far focused on a small part of the attack surface, particularly on issues related to the interaction between the user and the SPA devices. To the best of our knowledge, this is the first article to conduct such a comprehensive review and characterization of the security and privacy issues and countermeasures of SPA.
