Secure by Design: Bake Security into Software

In a digital world where vulnerabilities are often introduced at the development stage, security can no longer be an afterthought. Secure by Design: Bake Security into Software presents a modern, proactive approach to building software that is secure from the very first line of code.
This book explains why retrofitting security after deployment is costly, risky, and often ineffective. It explores how design decisions, architecture choices, and development practices directly influence an application’s security posture. Rather than focusing only on tools, the book emphasizes mindset, principles, and processes that help teams prevent vulnerabilities before they are created.
Inside this book, readers will learn:
• Why security must start at the design and architecture level
• How insecure design decisions lead to exploitable systems
• How to integrate security into the software development lifecycle
• How developers and security teams can collaborate effectively
• How secure design reduces long-term risk, cost, and rework
Written in a clear, practical, and development-focused style, this book is ideal for software developers, architects, DevOps engineers, and security professionals. Secure by Design empowers readers to build resilient, trustworthy software by embedding security into the foundation of modern application development.
