  With the increasing usage of smartphones a plethora of security solutions are
being designed and developed. Many of the security solutions fail to cope with
advanced attacks and are not aways properly designed for smartphone platforms.
Therefore, there is a need for a methodology to evaluate their effectiveness.
Since the Android operating system has the highest market share today, we
decided to focus on it in this study in which we review some of the
state-of-the-art security solutions for Android-based smartphones. In addition,
we present a set of evaluation criteria aiming at evaluating security
mechanisms that are specifically designed for Android-based smartphones. We
believe that the proposed framework will help security solution designers
develop more effective solutions and assist security experts evaluate the
effectiveness of security solutions for Android-based smartphones.
