The increase in the popularity of smartphones has brought with it a significant amount of cybercrime and state-sponsored exploitation in the field. This master's thesis examined a hierarchical structural model of the cyber environment, utilizing the model's various layers as a framework for understanding cyber threats that occur in the context of smartphones.\nThe hierarchical structural model of the cyber environment was tailored for the research, making it suitable for use in the context of smartphones. The theoretical part of the thesis revealed that the number of cyber threats targeting smartphones is on a significant rise. The quantity and quality of attack vectors targeting smartphones now correspond to those directed at computers. Predictions about the future development of smartphones also indicate that there are expected to be new, even greater threats to smartphones and smartphone users in the cyber operational environment. The empirical part of the thesis was conducted as a qualitative content analysis, and the data was collected through semi-structured interviews. The results of the interviews revealed that compared to previous studies, smartphone users' knowledge of and preparedness against various cybersecurity threats are generally at a good level.\nAccording to the research, smartphone users are very aware of physical threats such as the possibility of their smartphones being stolen, lost, or damaged. At the same time, smartphone users actively try to prevent these events from happening effectively. Smartphone users are also meticulous about the up-to-date and legitimate use of operating systems and device firmware. The study shows that, in terms of security, users are less cautious when it comes to installing and using various applications.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2023-11-14T06:53:55Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-11-14T06:53:55Z (GMT).
