Comparative Study of Protection Mechanisms for Mobile Operating Systems

Today’s smartphone market is increasingly dominated by three operating systems: Apples’s iOS (50% market share according to Admob),  Symbian OS (used e.g. by Nokia’s and some of Ericsson’s phones, 18% market share), and Google’s Android (24%, used e.g. by HTC, Ericsson,...). Although there are a variety of other operating systems such as RIM’s BlackBerry OS and Windows Mobile, their market share is comparatively small. Each of the operating systems Symbian, iOS, and Android use different concepts to protect the integrity of Software and Firmware on the mobile device and e.g. prevent users from installing malware-infected programs. At the same time users increasingly use their smart phones for Internet access, accessing their email and start storing more and more sensitive information on their mobile phones. This on the one hand increases the ways in which mobile phones can be infected with malware and on the other hand makes mobile devices increasingly attractive as an attack target.
