Lock It Down: Mobile Security Engineering: Protecting iOS and Android Applications from Real Threats

By RICHARD BOOZMAN

Mobile apps handle sensitive data every day.

Authentication tokens, personal information, payment details, location data, and business logic all live inside applications that attackers constantly target. Security can no longer be treated as an afterthought.

"Lock It Down" is a practical, engineering focused guide to securing modern mobile applications across iOS and Android platforms.

This book teaches developers how to identify risks, reduce vulnerabilities, and build mobile systems that remain secure in real world environments.

Why mobile security matters

Modern mobile threats include:

insecure API communicationcredential theftreverse engineeringmalicious device tamperinginsecure local storageweak authentication systemsruntime manipulation attacks

Without strong security practices, even polished apps can expose users and businesses to serious risk.

This book shows you how to defend against those threats systematically.

What you will learnfundamentals of mobile application securitysecure authentication and session managementprotecting APIs and backend communicationsecure local storage practicesencryption and key managementcertificate pinning and transport securitydefending against reverse engineeringruntime protection and tamper detectionsecure coding practices for iOS and Androidsecurity testing and vulnerability assessmentFrom vulnerable apps to resilient systems

Throughout the book, you will learn how to:

identify common mobile security weaknessessecure sensitive application dataharden mobile apps against attacksdesign safer authentication workflowsprotect APIs from abusebuild security into the development lifecycle

Each chapter focuses on practical defensive engineering techniques used in production mobile applications.
