Certified Information Systems Security Professional credential artwork

Certified Information Systems Security Professional (CISSP) Exam Guide

Validates knowledge of designing and managing security programs, including risk, architecture, access control, operations and software security.

Prepare across all eight domains, including the ones outside your day-to-day role. Learn how technical controls support business needs, then practise choosing the best response to a security scenario. The adaptive exam requires a decision on each question before you move on.

Question types

Choose the single best answer from four options; one is correct and three are distractors.

CertUp example

A company's CEO asks why a proposed backup project is ranked above a new firewall. What should the security manager show first?

  1. The vendor's list of firewall features
  2. The business impact and likelihood of the risks each project would reduce
  3. The number of staff who would use each system
  4. The purchase price of each project
Show answer

The business impact and likelihood of the risks each project would reduce. Security spending is prioritised by the risk it addresses, not by features or price alone.

Eligibility and booking

Create an ISC2 account and schedule with Pearson VUE. After passing, submit the endorsement application and pay your first annual fee.

Make a study plan

Map your experience to the outline first. Use one main course or guide, then focus your review on the domains you know least well.

Most candidates spend 120–250 hours. Plan for the low end if you work across most of the eight domains; plan for the high end if you have gaps in several domains or are returning to study after a long break.

Apply the question’s role. Identify what the question asks you to do. A governance decision, an incident response and a technical configuration need different actions.

Practice with mock exams

Use a question bank to find weak concepts and review the reasoning behind each option. Add timed practice so you can make decisions without returning to earlier questions.
