Architecting Zero-Trust Systems: Security Engineering for Microservices, Cloud, and Edge

Reactive PublishingBuild uncompromised, resilient systems in modern distributed environments.Traditional perimeter-based security is no longer sufficient. In today's decentralized infrastructure, spanning hybrid clouds, microservice meshes, and edge computing nodes, every network boundary is permeable, and trust must never be assumed.Architecting Zero-Trust Systems delivers a comprehensive, engineering-first guide to implementing strict, continuous verification across complex software architectures. Designed for systems architects, site reliability engineers, and security professionals, this book translates the abstract principles of Zero Trust into practical, production-ready design patterns.What You Will Learn- Core Principles of Zero Trust: Move beyond "trust, but verify" to an absolute model of "never trust, always verify."- Identity as the Perimeter: Implement robust, cryptographically backed identity and access management (IAM) strategies for services, workloads, and end-user devices.- Microservices & Mesh Security: Enforce continuous authentication, fine-grained authorization, and mutual TLS (mTLS) communication across distributed service architectures.- Cloud & Edge Convergence: Design secure access policies and isolation boundaries across public clouds, hybrid environments, and low-latency edge deployment targets.- Continuous Attestation & Threat Mitigation: Implement dynamic risk engine models, telemetry tracking, and automated response patterns to minimize attack surfaces.Whether you are refactoring legacy microservices or designing a multi-cloud enterprise platform from scratch, Takehiro Kanegi provides the tactical frameworks required to build resilient, threat-resistant systems.
