Looks like a nice intro to mobile security.
IEEE Computer
Smartphones have become an essential part of human life and its usage has grown exponentially in the past few years. The growth of smartphone usage can be directly linked to its ability to support third-party applications that are offered through online application markets. Due to its worldwide adoption and widespread popularity, the mobile malware attacks also growing at an alarming rate (http://bit.ly/sbtujI). Malware authors make use of third-party applications to inject malicious content into smartphones and thus compromise phone’s security. In response, mobile security research has become critical and focused on protecting smartphones from malware attacks and other security threats. In this paper, we present a survey of techniques that are used to detect mobile malware in the wild and discuss the limitations of current techniques and provide some tips to protect smartphones from potential security threats.
