Ship faster-without shipping security holes.
Modern software moves fast. Attackers move faster.
Whether you are building web apps, APIs, mobile apps, or managing production systems under pressure, Secure Software Development gives you the practical security knowledge you need to build with confidence from day one.
This is not a theory-heavy security book full of abstract concepts and academic detours. It is a hands-on guide for developers, engineers, and technical teams who want to integrate security into real development workflows-without slowing delivery to a crawl.
Inside, you'll learn how to make better security decisions across the full software lifecycle: from authentication and authorization to threat modeling, secure coding, encryption, API protection, logging, monitoring, and incident response.
You'll discover how to:
- defense in depth and the Swiss Cheese Model
- shift-left security and secure development workflows
- authentication and authorization beyond passwords
- secure coding practices and real-world vulnerability prevention
- encryption fundamentals for developers
- threat modeling with STRIDE and attacker-focused thinking
- web application security, including XSS, CSRF, SQL injection, CSP, and browser protections
- mobile app security pitfalls and how to avoid them
- API security, including keys, JWTs, mutual TLS, rate limiting, and OWASP API risks
- logging, monitoring, forensics, and audit trails
- incident response playbooks, containment, recovery, and post-incident learning
From solo developers to teams running complex microservices, this book helps you turn security from an afterthought into a development advantage.
If you write code, review pull requests, deploy infrastructure, or get pulled into production incidents at 3 a.m., this book will help you ship software that is not just fast and reliable-but resilient and secure.
Build better. Ship smarter. Defend earlier.
