＜p＞Perimeter security has failed, and attackers now walk through the front door with stolen credentials. This book gives architects and security leaders a practical blueprint for building zero trust that actually works across hybrid enterprises.＜/p＞ ＜p＞Zero Trust Architecture is the practitioner-and-decision-maker guide to building zero-trust architecture as the discipline it has become rather than the slogan it has been sold as. Across an Author's Note, a scenario-driven Introduction, and ten chapters anchored to a continuous reference environment at Meridian Logistics Group, the book builds the architecture from its foundational trust crisis through identity, microsegmentation, continuous verification, ZTNA and software-defined perimeters, AI/ML applied to zero trust, IoT and operational technology, data-centric security across hybrid and multi-cloud boundaries, and the automation, orchestration, and DevSecOps patterns that make the architecture sustainable.＜/p＞ ＜p＞Three pillars organize the work. Identity is the foundation: every access request begins with verified identity, for humans, machines, and workloads alike. Microsegmentation contains the blast radius when prevention fails, dividing the network interior into discrete zones with explicit traffic policy at every boundary. Continuous verification turns trust from a binary login decision into a variable re-evaluated throughout each session, supported by signal collection, posture management, and policy enforcement.＜/p＞ ＜p＞The book is engineered for two audiences who are usually in the same room but rarely read the same material. The main narrative speaks in a voice that assumes technical fluency without assuming a specific stack. "Geeks Only" sections deepen the technical detail for engineers and architects. "Manager's Decision Guide" sections translate the architecture into the prioritization logic and language CISOs and program leaders need for board, audit, and budget conversations. Federal mandatesーEO 14028, OMB M-22-09, FISMA modernization, and CMMCーare integrated throughout rather than confined to a sidebar.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。
