Summarize with:

The CISSP exam covers eight domains, led by Security and Risk Management at 16%, and is delivered as a computerized adaptive test of 100 to 150 items over 3 hours with a passing score of 700 out of 1000. This guide covers what each domain includes, how the adaptive exam works, ISC2's five-year experience requirement and the Associate of ISC2 path, and the new exam outline that takes effect on April 15, 2027. All exam facts come from ISC2's published pages, and the domain summaries are our own wording of the outline.

The Eight CISSP Domains and Their Weights

ISC2's current CISSP exam outline took effect on April 15, 2024. It has eight domains with average weights that add up to 100%. Domain 1, Security and Risk Management, is the largest at 16%, while Asset Security and Software Development Security are the smallest at 10% each.

DomainNameWeightWhat it covers
1Security and Risk Management16%Security concepts and governance, compliance and legal and regulatory issues, ethics, security policies and standards, business continuity requirements, personnel security, risk management, threat modeling and security awareness
2Asset Security10%Identifying and classifying information and assets, ownership, privacy, data retention, and choosing controls to handle data securely through its life
3Security Architecture and Engineering13%Secure design principles, security models, cryptography, secure system and facility design, and weaknesses in architectures and systems
4Communication and Network Security13%Network models and secure network design, network components, secure communication channels, wireless and VPN technologies
5Identity and Access Management (IAM)13%Physical and logical access control, identification and authentication, federated identity, authorization mechanisms and the identity and access provisioning lifecycle
6Security Assessment and Testing12%Assessment and test strategies, security control testing, collecting security process data, analyzing test output, and internal, external and third-party audits
7Security Operations13%Investigations, logging and monitoring, configuration and change management, incident management, disaster recovery, resource protection and physical security operations
8Software Development Security10%The software development lifecycle, security controls in development environments, secure coding, assessing software security and the risks of acquired software

The weights are averages, so the share of questions from each domain on your particular exam can vary. The summaries above are our own wording, and ISC2's outline is the authoritative source for the exact topics.

How the CISSP Exam Works

The CISSP uses computerized adaptive testing (CAT), which means the exam adjusts to your answers and its length varies. According to ISC2, the exam has 100 to 150 items, a time limit of 3 hours, multiple-choice and advanced item types, and a passing score of 700 out of 1000 points. It is offered in Chinese, English, German, Japanese and Spanish at ISC2-authorized Pearson testing centers, and Chinese-language exams are offered only during select windows.

Passing score700 out of 1000

Because the test is adaptive, you cannot skip ahead or return to earlier questions the way you can on a fixed-form exam, so pacing and a steady answer-by-answer approach matter.

Experience Requirements and the Associate Path

ISC2 requires a minimum of five years of cumulative, full-time work experience in at least two of the eight CISSP domains. A four-year bachelor's or master's degree in computer science, information technology or a related field, or a credential from ISC2's approved list, can satisfy up to one year of the requirement.

If you pass the exam without the required experience, you can become an Associate of ISC2 and then have six years to earn the five years of experience. This makes the exam reachable earlier in a career, but the credential is not the full CISSP until the experience requirement is met.

What Changes on April 15, 2027

ISC2 says the CISSP exam will move to a new outline on April 15, 2027. ISC2's page links to the new outline but does not list its domains or weights in the page text, so read the new outline PDF on ISC2's site for the exact changes. If you plan to take the exam before that date, study the current outline. If you plan to test after it, study the new one. Confirm which outline applies to your test date on ISC2's site before you start.

How to Approach CISSP Study

The CISSP is a management-level exam, and widely shared advice from successful candidates is to answer as a risk-focused manager would, choosing the response that best serves the organization and its business objectives, not the most technical option. Treat that as a study heuristic, not an official ISC2 statement.

Study by domain, weighted by size

Give Domain 1 the most attention at 16%, then spread time across the 12% to 13% domains, and keep the two 10% domains in rotation so they do not fade.

Practice with scenarios, not definitions

Management-level questions ask for the best or most appropriate action in a situation, so practice choosing between several plausible answers and explaining why the others are worse.

Space your review over weeks

A widely cited review of learning techniques rated practice testing and spaced practice as high utility. Return to each domain several times instead of studying it once.

Simulate the adaptive format

Practice in long sessions of 100 or more questions so you are used to sustained focus over up to 3 hours with no going back.

CISSP Compared With Security+

Security+ is a foundational exam with a fixed form of up to 90 questions in 90 minutes, and CompTIA's V8 page recommends two years as a security administrator. The CISSP is a senior-level exam with a five-year experience requirement, an adaptive 100 to 150 item format over 3 hours, and a management and risk emphasis. Many people take Security+ early in a security career and the CISSP after several years of experience. See our guide to which CompTIA certification to take first for the CompTIA side of that path, and our CISSP vs CISM vs CEH comparison for how the CISSP stacks up against other senior credentials.

The bottom line

Know the eight domains and weight your study by size, practice with scenario questions that reward management-level judgment, and rehearse the adaptive format with long sessions. Confirm which outline applies to your test date, since the exam changes on April 15, 2027, and check ISC2's experience rules before you plan your timeline.
