About this exam

The Certified Information Systems Security Professional (CISSP) is a vendor-neutral credential from ISC2 aimed at experienced security practitioners who design, engineer and manage an organization's overall security posture rather than administer a single product. It is commonly pursued by security managers, architects, analysts, auditors, consultants and directors, as well as IT leaders moving into security leadership. The exam is built from an eight-domain outline: Security and Risk Management (16%), Asset Security (10%), Security Architecture and Engineering (13%), Communication and Network Security (13%), Identity and Access Management (13%), Security Assessment and Testing (12%), Security Operations (13%) and Software Development Security (10%). It is delivered by Computerized Adaptive Testing, runs up to three hours, contains 100 to 150 items in multiple-choice and advanced item formats, and requires a scaled score of 700 out of 1000. Candidates need five years of cumulative full-time experience across at least two domains, though a degree or approved credential can waive up to one year, and those without the experience can pass the exam and become an Associate of ISC2 with six years to qualify. Most candidates prepare with the official exam outline, ISC2 training options and disciplined domain-by-domain practice.

What you'll study

Common questions

About CISSP preparation

How is the CISSP exam delivered and how long is it?

It is delivered exclusively through Computerized Adaptive Testing, meaning question difficulty adjusts to your performance. You have three hours of testing time and will answer between 100 and 150 items. Because the engine stops when it has enough confidence in your ability estimate, candidates often finish with fewer items than the maximum.

What score do I need to pass?

The passing grade is 700 out of 1000 points on a scaled score. Scaled scoring means the raw number of correct answers is not what determines your result, so you cannot calculate a reliable pass threshold from a practice test percentage alone. Focus on consistent performance across all eight domains.

What item types appear on the exam?

The official item format is multiple choice and advanced item types. Advanced items can require you to evaluate scenarios in more depth than a simple recall question. Read each stem fully, because these items often reward the answer that reflects a manager's risk-based perspective rather than the most technical option.

How much work experience do I need before sitting the exam?

Candidates need a minimum of five years cumulative, full-time experience in two or more of the eight CISSP domains. A bachelor's or master's degree in computer science, IT or a related field, or an additional credential from the ISC2 approved list, may satisfy up to one year, and only one year can be waived. Part-time work and internships may count.

Can I take the exam without the required experience?

Yes. A candidate who lacks the required experience may pass the CISSP examination and become an Associate of ISC2. The Associate then has six years to earn the five years of required experience. This is a common route for capable practitioners who are early in their security careers.

In what order should I study the domains?

Domain 1, Security and Risk Management, is the heaviest at 16% and introduces risk, governance and control language used throughout the exam, so it is a sensible starting point. Then cover the four 13% domains, since they carry the most weight collectively, before finishing with Asset Security and Software Development Security at 10% each.

What are the most common failure modes?

Candidates typically fail by answering as technicians rather than as risk advisors, memorizing acronyms without understanding trade-offs, and neglecting low-weight domains entirely. The exam also rewards reading the whole question: many stems ask for the best first step, the primary goal or the most cost-effective control, not the strongest control.

How long do I have to schedule the exam after buying it?

An exam-only purchase must be scheduled and administered within 365 days of purchase. If you buy the Peace of Mind Protection option, two attempts are included in the purchase price and you have 180 days from purchase to sit both attempts, in accordance with the retake policy.

What languages are available, and are there scheduling restrictions?

The exam is offered in Chinese, English, German, Japanese and Spanish. Chinese-language CISSP exams are only available during select appointment windows: March 1-31, June 1-30, September 1-30 and December 1-31. Candidates testing in Chinese should book early within one of those windows.

Is the exam content changing soon?

Yes. Effective April 15, 2027, the CISSP exam will be based on a new exam outline. The domain weights and exam details currently in force come from the outline effective April 15, 2024. If you test on or after the 2027 date, study against the new outline rather than the current one.
