There is a lack of consensus when using the term "cyberspace" [1]. Computers and network devices are prominent in definitions of cyberspace; less common is the essential and inclusion of human users. However, the human user is both implicitly integral to and actively part of the cyberspace. Cyberspace is often conceptualized as three layers of interconnected networks: social, information and geospatial (physical) [2]. These represent an indirect human element within cyberspace. This is characteristic of related fields, such as cybersecurity, where human-centered research has been lagging behind technological aspects. A model that incorporates the human user in cyberspace is needed to direct future research and improve security and usability (navigation). A new human-centric model of cyberspace is proposed (the HCCM), with the user as a physical and integral entity, together with recognition of the cognitive representation of cyberspace. It focuses on boundaries and transformation points between objects and spaces and offers a platform for future human-centric research in cybersecurity.
