About the Book
The CISSP remains the gold standard in information security, and in 2026 it has never been more valuable or more demanding. The exam no longer rewards memorization. It tests whether you can think like a security leader, weigh business risk, and choose the BEST answer in realistic scenarios. With the 2026 update placing new emphasis on cloud security, zero trust, AI-driven security operations, supply chain risk, and modern software development, studying from outdated material is a costly mistake.
CISSP Exam Preparation 2026 gives you a clear, structured path to passing on your first attempt. Organized to mirror the official (ISC)² exam outline, it dedicates a full chapter to each of the eight domains of the Common Body of Knowledge: Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security.
Every chapter is built for retention and exam readiness. You will find Key Term callouts for critical vocabulary, Mnemonic boxes that make complex lists stick, Exam Tip notes that reveal how topics are likely to be tested, and realistic practice questions with full explanations of both correct and incorrect answers. Reference tables, textual diagrams, and real-world examples help you build a durable mental model of each domain rather than a pile of disconnected facts.
Beyond the domains, the book includes a complete 90-day study plan, proven test-taking techniques for the Computerized Adaptive Testing (CAT) format, and dedicated chapters on cloud security, zero trust, governance, risk and compliance, and emerging trends. It closes with guidance on endorsement, maintaining your credential, and building your career beyond the CISSP. Whether you are a seasoned practitioner or newer to the field, this is the roadmap that takes you from first page to certified professional.
