CISA Certified Information Systems Auditor Study Guide

Pass the ISACA CISA certification exam on your first attempt.

This CISA exam prep guide is built for IS auditors and information security professionals with 3-7 years of experience who are ready to formalise their credentials and move into senior audit, governance, and assurance roles. Most CISA guides on the market were written before the August 2024 Exam Content Outline took effect, and before the ISACA IT Audit Framework, 5th Edition (ITAF 5) was published in March 2026. Studying from those guides means over-preparing for content that has been reduced and under-preparing for content that has been refreshed. This guide is fully aligned to both.

What's inside:

• Full coverage of all five CISA domains aligned to the August 2024 Exam Content Outline: Information System Auditing Process (18%), Governance and Management of IT (18%), Information Systems Acquisition, Development, and Implementation (12%), Information Systems Operations and Business Resilience (26%), and Protection of Information Assets (26%)
• Full integration of the ISACA IT Audit Framework, 5th Edition (ITAF 5), including the new AI governance and emerging technology guidance
• 200+ scenario-based CISA practice questions written at application and analysis levels of Bloom's taxonomy, matching the cognitive demand of the real exam
• Two full-length 75-question practice exams with three-part answer explanations: the correct answer rationale, why each distractor is wrong, and the underlying ISACA mindset principle at play
• A Quick Reference chapter built for the final 48 hours of preparation, including domain summaries, framework cheat sheets, top 20 exam traps, and a cram checklist
• Coverage of the new CISA Associate pathway introduced by ISACA in July 2025

Free CertCrush portal access included. Every copy includes a free voucher code redeemable at certcrush.app, giving you full access to the CertCrush online study platform: online practice exams with timed mode, instant scoring, and detailed analytics; digital flashcards covering every key term, framework, and ISACA concept; the complete online study guide in a searchable, mobile-friendly format; a downloadable PDF version of this entire book; and regular content updates as ISACA exam policies, ITAF guidance, and content outlines evolve. This combined book-plus-portal approach mirrors how serious candidates actually study: deep reading in the book, active recall and spaced practice in the portal, and final cramming with the PDF and flashcards.

Why this guide works. The CISA exam does not reward memorisation. It rewards candidates who can apply professional judgment the way a senior IS auditor would. Every chapter teaches the audit mindset, not just the audit content. Content depth is proportional to actual exam weighting: Domains 4 and 5 together account for 52% of the exam, and they receive 52% of the depth in this guide. No filler, no padding, no over-coverage of reduced topics.

Who this is for: IS auditors with 3-7 years of experience, information security professionals moving into audit, governance, or assurance roles, candidates pursuing the new CISA Associate pathway, and CISSP, CISM, and CRISC holders adding CISA to their portfolio.

If you are serious about passing the CISA certification exam on the first attempt, this is the guide, and the platform, that gets you there.
