Zero Trust APIs

Most APIs are built on assumptions.Assumption that users are trusted.Assumption that internal services are safe.Assumption that tokens won't be abused.That's exactly why they fail.Zero Trust APIs is a practical guide for developers who want to design systems that don't rely on trust at all.This book shows you how to build APIs where:Every request is verifiedEvery service is treated as potentially hostileEvery token is validated and controlledEvery failure is containedYou'll learn how to move from "e;it works"e; to "e;it survives attacks."e;What You'll LearnHow Zero Trust principles apply to API designAuthentication vs Authorization (and why most get it wrong)Secure token handling (JWT, API keys, rotation strategies)Protecting internal APIs from lateral movement attacksRate limiting and abuse prevention techniquesDesigning service-to-service authentication securelyBuilding resilient systems with least privilege accessLogging, monitoring, and detecting suspicious behaviorWhy This Book is DifferentThis is not theory.This is not compliance talk.This is a developer-first, production-focused playbook filled with:Real-world scenariosSimple architecture patternsPractical implementation strategiesWho This Book is ForBackend developers building APIsEngineers working with microservicesSaaS founders handling sensitive dataDevOps teams securing infrastructureWhat You'll AchieveBy the end of this book, you'll be able to:Design APIs that assume breach by defaultEliminate common security blind spotsBuild systems that scale securelySleep better knowing your backend won't collapse under attackIf your API is exposed to the internet, this is not optional.
