What you will learnThis book provides a comprehensive, step-by-step guide to implementing Microsoft Purview's data security and governance capabilities across the full lifecycle of enterprise information. It is designed for IT professionals, security architects, compliance officers, and technical writers who need to build, document, and operationalize a robust data protection strategy. Below is a high-level overview of the book chapters;
Chapter 1: Information ProtectionMicrosoft Purview enables classification, labeling, and protection of sensitive content using sensitivity labels and policies. It supports automated discovery and consistent enforcement across workloads, helping organizations meet compliance and governance standards in Microsoft 365, endpoints, and third-party platforms.
Chapter 2: EncryptionPurview uses Microsoft Information Protection encryption to secure data at rest and in transit. Integrated with sensitivity labels, it applies rights management services to restrict access and control usage, ensuring only authorized identities can decrypt emails, documents, and cloud-based assets.
Chapter 3: Data Loss PreventionData loss prevention policies identify and block unauthorized sharing of sensitive data. By scanning communications, files, and endpoints, Purview applies controls that prevent risky actions, notify users, and trigger incident management workflows to preserve information boundaries while supporting day-to-day productivity.
Chapter 4: Data Security InvestigationsInvestigation tools in Purview help analysts detect breaches, policy violations, and misuse. With insights from audit logs, risk signals, and activity alerts, teams can examine suspicious behavior, triage incidents, and take corrective action across the Microsoft 365 environment.
Chapter 5: Data Security Posture ManagementThis capability assesses data sensitivity, exposure risk, and policy coverage. Purview visualizes data flows and protection gaps, offering dashboards and remediation insights to improve security hygiene, align with compliance standards, and reinforce organizational governance efforts.
Chapter 6: Insider Risks ManagementMicrosoft Purview monitors user behavior to detect data leaks, theft, and violations. Using analytics and policy templates, it provides anonymized case management, investigation capabilities, and remediation workflows that help address insider threats with discretion and compliance.
Chapter 7: Information BarriersInformation Barriers restrict communication between defined user segments to prevent unauthorized sharing and conflicts of interest. Often used in regulated industries, they enforce ethical walls across Teams and Exchange to maintain regulatory and organizational separation.
Chapter 8: Privileged Access ManagementPrivileged access management reduces risks from elevated permissions by enforcing time-based and approval-driven access to sensitive systems. Purview supports just-in-time role activation, scoped permissions, and full auditing to ensure control, accountability, and minimized attack surfaces.
