Abstract [en]

The purpose of this study was to enhance the “Hierarchical Framework Model of Mobile Security” proposed by the researchers from the University of Oulu in order to make it more technology oriented and include information about attacks and corresponding protection. A qualitative study was done that consisted of content analysis and three structured e-mail interviews with three security professionals. The aim of content analysis was to identify threat and safeguard domains that can be used to enhance the framework. It was done by reviewing the current research, technical whitepapers and market offers in the area of mobile security. During the interviews, respondents were asked to review the proposed enhancements. The new framework has the same layer hierarchy, however each layer was modified to contain three additional sub-layers: threat domains, safeguard domains, and technical controls. Things that were considered not having any direct security implications on mobile phones (like multimedia copyright protection) were removed. The focus was on technical solutions leaving the higher-level mechanisms for future research. After reviewing the new framework, all interviewees agreed that the new solution is improved over the original. It is easy to use, and can be applied during the risk assessment process. Several drawbacks were identified in the new version, some of which, however, were fixed after the review. This goes along with the conclusions that author draws about the framework development process. This process should include the following phases: learning about the problem, analyzing solutions, identifying the abstraction levels, designing, iterating.
