The series is published by Aced It Publications to a single editorial standard. Each chapter maps to the official objectives. Technical specifics are verified against source documentation. Practice questions are grouped by domain and include an explanation for every answer choice. The aim is a guide you can read end to end and take into the exam room with confidence.

About this book

The Microsoft SC-900 (Microsoft Certified: Security, Compliance, and Identity Fundamentals) is Microsoft's entry-level credential covering the full Microsoft security and compliance estate. It is structured into four domains: concepts of security, compliance, and identity; capabilities of Microsoft Entra; capabilities of Microsoft security solutions; and capabilities of Microsoft compliance solutions. The exam is delivered through Pearson VUE and requires a score of 700 or greater to pass.

This guide is written to the November 7, 2025 skills-measured outline with current Microsoft product names throughout. Microsoft Entra ID, Microsoft Defender XDR, the Microsoft Defender portal, Microsoft Sentinel, and Microsoft Purview appear in their current forms end to end, with a parenthetical note at first mention where the name changed from an older brand. Each chapter maps to a numbered SC-900 objective, opens the concept before the exam tests it, and closes with Exam Tip and Common Pitfall callouts and a Key Takeaways summary. The domain-tagged practice question bank includes an explanation for every answer choice, not just the correct one, modeled on the free Microsoft Practice Assessment style.

Who it is for

This book is written for business stakeholders coming up to speed on Microsoft cloud security vocabulary, new and existing IT professionals supporting Microsoft 365 or Azure environments, students entering the Microsoft certification ladder, and generalists in compliance, audit, or consulting roles who need working fluency in the Microsoft security and compliance stack. It also serves candidates who plan to continue to SC-200, SC-300, or SC-100 after passing and want a grounded vocabulary before tackling the associate-level exams. It assumes general computer literacy and a basic familiarity with Microsoft 365 or Azure. It does not assume any prior security training or hands-on experience with the Defender or Purview product families.
