Ever-present cyber threats have been increasing against mobile devices in recent years. As Android emerges as the leading platform for mobile devices, security issues associated with the Android platform become a growing concern for personal and enterprise customers. Android Security: Attacks and Defenses provides the reader with a sense of preparedness by breaking down the history of Android and its features and addressing the methods of attack, ultimately giving professionals, from mobile application developers to security architects, an understanding of the necessary groundwork for a good defense.

In the context and broad realm of mobility, Dubey and Misra bring into focus the rise of Android to the scene and the security challenges of this particular platform. They go beyond the basic security concepts that are already readily available to application developers to tackle essential and advanced topics such as attack countermeasures, the integration of Android within the enterprise, and the associated regulatory and compliance risks to an enterprise. By reading this book, anyone with an interest in mobile security will be able to get up to speed on the Android platform and will gain a strategic perspective on how to protect personal and enterprise customers from the growing threats to mobile devices. It is a must-have for security architects and consultants as well as enterprise security managers who are working with mobile devices and applications.

The launch of the Apple iPhone in 2007 started a new era in the world of mobile devices and applications. Googles Android platform has emerged as a serious player in the mobile devices market, and by 2012, more Android devices were being sold than iPhones. With mobile devices becoming mainstream, we have seen the evolution of threats against them. Androids popularity has brought it attention from the bad guys, and we have seen attacks against the platform on the uptick.

In this book, we analyze the Android platform and applications in the context of security concerns and threats. This book is targeted towards anyone who is interested in learning about Android security or the strengths and weaknesses of this platform from a security perspective. We describe the Android OS and application architecture and then proceed to review security features provided by the platform. We then describe methodology for analyzing and security testing the platform and applications. Towards the end, we cover implications of Android devices in the enterprise environment as well as steps to harden devices and applications. Even though the book focuses on the Android platform, many of these issues and principles can be applied to other leading platforms as well.
