  Virtual Reality (VR) is a multibillionaire market that keeps growing, year
after year. As VR is becoming prevalent in households and small businesses, it
is critical to address the effects that this technology might have on the
privacy and security of its users. In this paper, we explore the
state-of-the-art in VR privacy and security, we categorise potential issues and
threats, and we analyse causes and effects of the identified threats. Besides,
we focus on the research previously conducted in the field of authentication in
VR, as it stands as the most investigated area in the topic. We also provide an
overview of other interesting uses of VR in the field of cybersecurity, such as
the use of VR to teach cybersecurity or evaluate the usability of security
solutions.
