Cloud breaches rarely begin with a sophisticated exploit. Far more often they begin with something ordinary: a storage bucket left public, an access key that never expired, an account nobody remembered creating, or logging that was quietly switched off. Cloud Security Hygiene teaches the disciplined, everyday practices that prevent those failures. Written by a cybersecurity professor with 25 years of experience in the US military and IT, it organizes cloud security around four simple questions every organization should be able to answer: What do we have? Who can access it? How is it configured? What has changed? Inside you will learn how to: Build governance and guardrails across AWS, Microsoft Azure, and Google Cloud Apply Zero Trust and least-privilege identity practices to people, workloads, and AI agents Use Cloud Security Posture Management (CSPM) and CNAPP to find and fix misconfigurations Protect data, secrets, containers, Kubernetes, serverless functions, and CI/CD pipelines Strengthen logging, detection, incident response, and recovery Map hygiene practices to NIST CSF 2.0, CIS Controls, ISO 27001, SOC 2, and other frameworks Prepare for what comes next, from AI-driven automation to post-quantum cryptography Each chapter includes learning objectives, real-world case studies, diagrams, tables, key terms, and review questions. That makes the book well suited to college courses, certification study, and professional teams building a cloud security program. A Cloud Hygiene Maturity Model gives readers a practical roadmap from ad hoc practices to automated, predictive security. Whether you are a student entering cybersecurity or an architect securing a multi-cloud enterprise, this book shows how consistent hygiene turns cloud security from constant firefighting into a sustainable practice.
