In the last years, mobile devices have introduced a new dimension into life and work. Increasing capabilities have caused a paradigm shift in the way users view and use mobile devices [1]. Smartphones and other mobile devices, such as tablet PCs, are small, easy to carry and powerful in computational and storage capabilities. Particularly smartphones and tablet PCs are being used in a business context and replacing classic business mobile phones and to some extent, notebook PCs. Organizational decision-makers have increasingly come to accept the use of mobile and private devices and applications in the organizational IS environment [2]. Hence, research studies emphasize management’s concerns about the protection of organizational information asset [1,3]. Smartphone users’ behavior in different situations and how they cope with security measures become important in the organizational information security context. While researchers focus on technical issues or on organizational perspectives of mobile security (e.g. [1]), behavioral research is very limited up to now [3].
