"I honestly didn’t believe I’d learn much from the book because I’ve been working on Android security for many years. This belief could not have been more wrong. Android Security Internals has earned a permanent spot on my office bookshelf." —Jon “jcase” Sawyer, from the Foreword There are more than one billion Android devices in use today, each one a potential target. Unfortunately, many fundamental Android security features have been little more than a black box to all but the most elite security professionals—until now. In Android Security Internals, top Android security expert Nikolay Elenkov takes us under the hood of the Android security sys­tem. Elenkov describes Android security archi­tecture from the bottom up, delving into the imple­mentation of major security-related components and subsystems, like Binder IPC, permissions, cryptographic providers, and device administration. You’ll learn: * How Android permissions are declared, used, and enforced * How Android manages application packages and employs code signing to verify their authenticity * How Android implements the Java Cryp­­­tog­raphy Architecture (JCA) and Java Secure Socket Extension (JSSE) frameworks * About Android’s credential storage system and APIs, which let applications store cryptographic keys securely * About the online account management framework and how Google accounts integrate with Android * About the implementation of verified boot, disk encryption, lockscreen, and other device security features * How Android’s bootloader and recovery OS are used to perform full system updates, and how to obtain root access With its unprecedented level of depth and detail, Android Security Internals is a must-have for any security-minded Android developer.

Battle-Tested Best Practices for Securing Android Apps throughout the Development Lifecycle Android’s immense popularity has made it today’s #1 target for attack: high-profile victims include eHarmony, Facebook, and Delta Airlines, just to name a few. Today, every Android app needs to resist aggressive attacks and protect data, and in Bulletproof Android™, Godfrey Nolan shows you how. Unlike “black hat/gray hat” books, which focus on breaking code, this guide brings together complete best practices for hardening code throughout the entire development lifecycle. Using detailed examples from hundreds of apps he has personally audited, Nolan identifies common “anti-patterns” that expose apps to attack, and then demonstrates more secure solutions. Nolan covers authentication, networking, databases, server attacks, libraries, hardware, and more. He illuminates each technique with code examples, offering expert advice on implementation and trade-offs. Each topic is supported with a complete sample app, which demonstrates real security problems and solutions. Learn how to Apply core practices for securing the platform Protect code, algorithms, and business rules from reverse engineering Eliminate hardcoding of keys, APIs, and other static data Eradicate extraneous data from production APKs Overcome the unique challenges of mobile authentication and login Transmit information securely using SSL Prevent man-in-the-middle attacks Safely store data in SQLite databases Prevent attacks against web servers and services Avoid side-channel data leakage through third-party libraries Secure APKs running on diverse devices and Android versions Achieve HIPAA or FIPS compliance Harden devices with encryption, SELinux, Knox, and MDM Preview emerging attacks and countermeasures This guide is a perfect complement to Nolan’s Android™ Security Essentials LiveLessons (video training; ISBN-13: 978-0-13-382904-4) and reflects new risks that have been identified since the LiveLessons were released.
