The ISC2®CISSP®Certified Information Systems Security Professional Official Study Guide, Tenth Edition, offers you a solid foundation for the Certified Information Systems Security Professional (CISSP) exam. By purchasing this book, you've shown a willingness to learn and a desire to develop the skills you need to achieve this certification. This introduction provides you with a basic overview of this book and the CISSP exam.
This book is designed for readers and students who want to study for the CISSP certification exam. If your goal is to become a certified security professional, then the CISSP certification and this CISSP Study Guide are for you. The purpose of this book is to adequately prepare you to take the CISSP exam.
The information presented here in this Introduction was based on the publicly available documentation from ISC2 as of April 15, 2024. However, these details and exam parameters are subject to change at any time based upon ISC2 operational decisions. Please consult isc2.org to confirm, verify, or learn about updated exam specifics.
Before you dive into this book, you need to have accomplished a few tasks on your own. You need to have a general understanding of IT and of security. You should have the necessary five years of cumulative full-time work experience (or four years if you have a college degree) in two or more of the eight domains covered by the CISSP exam. Part-time work and internship experience is also acceptable with conditions; see www.isc2.org/certifications/cissp/cissp-experience-requirements. If you are qualified to take the CISSP exam according to ISC2, then you are sufficiently prepared to use this book to study for it. For more information on ISC2, see the next section.
Alternatively, ISC2 allows for a one-year reduction of the five-year experience requirement if you have earned one of the approved certifications from the ISC2 prerequisite pathway. As of Q1 2024, the qualified certifications are:

You can use only one of the experience reduction measures, either a college degree or a certification, not both.
ISC2 offers an entry program known as an Associate of ISC2. This program allows someone without any or enough experience to qualify as a CISSP applicant to take the CISSP exam anyway and then obtain experience afterward. Associates are granted six years to obtain five years of security experience. Only after providing proof of such experience, usually by means of endorsement (discussed later), can the individual be awarded the full CISSP certification.
If you are just getting started on your journey to CISSP certification and do not yet have the work experience, then our book can still be a useful tool in your preparation for the exam. However, you may find that some of the topics covered assume knowledge that you don't have. For those topics, you may need to do some additional research using other materials, and then return to this book to continue learning about the CISSP topics.
The CISSP exam is governed by the International Information System Security Certification Consortium ISC2. ISC2 is a global nonprofit organization. It has the mission of “ISC2 strengthens the influence, diversity and vitality of the field through advocacy, expertise and workforce empowerment that accelerates cyber safety and cybersecurity in an interconnected world.”
ISC2 is operated by a board of directors elected from the ranks of its certified practitioners.
ISC2 supports and provides a wide variety of certifications, including CISSP, ISSAP, ISSMP, ISSEP, SSCP, CCSM, CCSP, CGRCSM, and CSSLP. These certifications are designed to verify the knowledge and skills of IT security professionals across all industries. You can obtain more information about ISC2 and its other certifications from its website at isc2.org.
The CISSP credential is for security professionals “with the knowledge, skills and abilities to lead an organization's information security program.”
The CISSP certification covers material from the eight topical domains. These eight domains are as follows:
Domain 1: Security and Risk Management
Domain 2: Asset Security
Domain 3: Security Architecture and Engineering
Domain 4: Communication and Network Security
Domain 5: Identity and Access Management (IAM)
Domain 6: Security Assessment and Testing
Domain 7: Security Operations
Domain 8: Software Development Security
These eight domains provide a vendor-independent overview of a common security framework. This framework is the basis for a discussion on security practices that can be supported in all types of organizations worldwide.
ISC2 has defined the qualification requirements you must meet to become a CISSP. First, you must be a practicing security professional with at least five years’ work experience or with four years’ experience and a recent IT or IS degree or an approved security certification (as mentioned previously). Professional experience is defined as security work performed (with or without pay) within two or more of the eight CISSP domains.
Second, you must agree to adhere to a formal code of ethics. The ISC2 Code of Ethics is a set of guidelines ISC2 wants all certification candidates to follow to maintain professionalism in the field of information systems security. You can find the ISC2 Code of Ethics at isc2.org/ethics.
The CISSP exam focuses on security from an overview perspective; it deals more with theory and concept than implementation and procedure. It is very broad but not very deep. To successfully complete this exam, you'll need to be familiar with every domain but not necessarily be a master of each domain.
The CISSP exam is in an adaptive format that ISC2 calls CISSP CAT (Computerized Adaptive Testing). For complete details of this form of exam presentation, please see www.isc2.org/certifications/CISSP/CISSP-CAT.
The CISSP CAT exam has a minimum of 100 questions and a maximum of 150. Not all items (i.e., questions) presented count toward your proficiency level, competency requirements, or passing status. There are 25 unscored questions that are called pre-test or unscored items by ISC2, whereas the scored questions are called operational items. The questions are not labeled on the exam as to whether they are scored (i.e., operational items) or unscored (i.e., pre-test questions). Test candidates will receive 25 unscored items on their exam, regardless of whether they achieve a passing rank at question 100 or see all of the 150 questions. However, an exam's pass/fail report is determined by only the last 75 operational items answered by the test candidate.
The CISSP CAT grants a maximum of three (3) hours to take the exam. If you run out of time before achieving a passing rank, you will automatically fail.
The CISSP CAT does not allow you to return to a previous question to change your answer. Your answer selection is final once you leave a question by submitting your answer selection.
To pass the CISSP CAT exam, you must score 700 out of a possible 1000 points, within the last 75 operational items (i.e., questions). If you do not achieve the minimum passing score after submitting your answer to question 150, then you fail. If you run out of time, then you fail.
If you do not pass the CISSP exam on your first attempt, you are allowed to retake the CISSP exam under the following conditions:
You can take the CISSP exam a maximum of four times per 12-month period. (Note that on the CISSP CAT FAQ the limit is defined as 3 times per a 12-month period.)
You must wait 30 days after your first attempt before trying a second time.
You must wait an additional 60 days after your second attempt before trying a third time.
You must wait an additional 90 days after your third or subsequent attempts before trying again.
The exam retake policy may be updated; you can read the most current version of the official policy here: www.isc2.org/Exams/After-Your-Exam.
You will need to pay full price for each additional exam attempt. However, ISC2 offers promotions from time to time that may allow you to retake an exam at no additional cost. This promotion has been called “Peace of Mind Protection,” but could be renamed. It is limited to first-time test-takers only and has time restrictions. Be sure to read the fine print before acting on any such promotional offers.
The CISSP CAT exam is available in English, Chinese, German, Japanese, and Spanish.
For more details and the most up-to-date information on the CISSP exam direct from ISC2, please visit www.isc2.org/Certifications/CISSP and download the CISSP Ultimate Guide and visit www.isc2.org/certifications/cissp/cissp-certification-exam-outline to download the CISSP Exam Outline. You might also find useful information on the ISC2 Insights blog at www.isc2.org/Insights.
The total number of questions you may see on the exam, the total number of questions that count toward your score, the means and methods of scoring, and the time limit for the test are things that ISC2 reevaluates and changes from time to time. The best advice for preparing is to always recheck the ISC2 website for up to date exam specifications and policies.
Most of the questions on the CISSP exam are four-option, multiple-choice questions with a single correct answer. Some are straightforward, such as asking you to select a definition. Some are a bit more involved, asking you to select the appropriate concept or best practice. And some questions present you with a scenario or situation and ask you to select the best response.
You must select the one correct or best answer and mark it. In some cases, the correct answer will be obvious to you. In other cases, several answers may seem correct. In these instances, you must choose the best answer for the question asked. Watch for general, specific, universal, superset, and subset answer selections. In other cases, none of the answers will seem correct. In these instances, you'll need to select the least incorrect answer.
Some multiple-choice questions may require that you select more than one answer; if so, these will state what is necessary to provide a complete answer.
In addition to the standard multiple-choice question format, the exam may include a few advanced question formats, which ISC2 calls advanced innovative questions. These include drag-and-drop questions and hotspot questions. These types of questions require you to place topics or concepts in order of operations, in priority preference, or in relation to proper positioning for the needed solution. Specifically, the drag-and-drop questions require the test taker to move labels or icons to mark items on an image. The hotspot questions require the test-taker to pinpoint a location on an image with a crosshair marker. These question concepts are easy to work with and understand, but be careful about your accuracy when dropping or marking.
ISC2 introduced the advanced innovative questions in 2014. They maintained a page describing these questions until 2017. While they still use this phrase to reference the question concepts, they no longer provide an explanation or examples of these questions on their website.
The CISSP exam consists of two key elements. First, you need to know the material from the eight domains. Second, you must have good test-taking skills. You have a maximum of 3 hours to achieve a passing standard with the potential to see up to 150 questions. Thus, you will have on average just over a minute for each question, so it is important to work quickly, without rushing, but also without wasting time.
Question skipping is not allowed on the CISSP CAT exam. You cannot return to view or change a previous question, and you're also not allowed to jump around, so one way or another, you have to come up with your best answer on each question as it is presented to you. If you don't know how to answer a question, then we recommend that you attempt to eliminate as many answer options as possible before making a guess. Then you can make educated guesses from a reduced set of options to increase your chance of getting a question correct. Since you have to answer every question presented, and you might not know the answer to some questions, you should develop a guessing strategy to select an answer promptly to minimize further wasting time.
Also note that ISC2 does not disclose if there is partial credit given for multiple-part questions if you get only some of the elements correct. So, pay attention to questions with checkboxes, and be sure to select as many items as necessary to properly address the question.
You will be provided with a dry-erase board and a marker to jot down thoughts and make notes. But nothing written on that board will be used to alter your score. That board must be returned to the test administrator prior to departing the test facility.
To maximize your test-taking activities, here are some general guidelines:
Read each question carefully, then read the answer options, and then reread the question.
Eliminate wrong answers before selecting the correct one.
Watch for double negatives.
Pay attention to universal terms, such as always or never.
Look for relationships between answer options, such as similes, antonyms, sets, groups, parent/child, category/example, etc.
Be sure you understand what the question is asking.
Manage your time. You can take breaks during your test, but this will consume some of your test time. You might consider bringing a drink and snacks, but your food and drink will be stored for you away from the testing area, and that break time will count against your test time limit. Be sure to bring any medications or other essential items, but leave all things electronic at home or in your car. You should avoid wearing anything on your wrists, including watches, fitness trackers, and jewelry. You are not allowed to bring any form of noise-canceling headsets or earbuds, although you can use foam earplugs. We also recommend wearing comfortable clothes and taking a light jacket with you (some testing locations are a bit chilly).

Finally, ISC2 exam policies are subject to change. Please be sure to check isc2.org for the current policies before you register and take the exam.
We recommend planning for a month or so of nightly intensive study for the CISSP exam. Here are some suggestions to maximize your learning time; you can modify them as necessary based on your own learning habits:
Take one or two evenings to read each chapter in this book.
Read and understand the Study Essentials for each chapter.
Complete the written labs from each chapter.
Answer all the review questions for each chapter.
Be sure to research each question that you get wrong in order to learn what you didn't know.
Review ISC2's Exam Outline to make sure you understand each listed item.
Use the flashcards included with the online study tools to reinforce your understanding of concepts.
Take the 4 full-length bonus practice exams provided in the online test engine.
We recommend spending about half of your study time reading and reviewing concepts and the other half taking practice exams. Students have reported that the more time they spent taking practice exams, the better they retained test topics. In addition to the practice tests with this Study Guide, Sybex also publishes ISC2 CISSP Certified Information Systems Security Professional Official Practice Tests, 4th Edition (ISBN: 978-1-394-25507-8). It contains 100 or more practice questions for each domain and four additional full-sized practice exams. Like this Study Guide, it also comes with an online version of the questions.
Once you have been informed that you successfully passed the CISSP certification, there is one final step before you are actually awarded the CISSP certification. That final step is known as endorsement. Basically, this involves getting someone who holds any ISC2 certification in good standing and is familiar with your work history to endorse you. Endorsement is the evaluation of your prerequisite qualifications (i.e., work experience) and the recommendation to ISC2 to award you the certification. Once you pass the CISSP exam, you will receive an email with instructions. However, you can review the endorsement application process at isc2.org/Endorsement. This URL is also where you initiate the endorsement process. You will need to know the ISC2 membership number of the person who will endorse you.
If you registered for CISSP, then you must complete endorsement within nine months of your exam. If you registered for Associate of ISC2, then you have six years from your exam data to complete endorsement. Once ISC2 accepts your endorsement, the certification process will be completed and you will be sent a welcome packet with confirmation of the certification achieved. You should also receive an email confirmation of the endorsement process’s completion and another when the certification is awarded to you.
Once you have achieved your CISSP certification, you must maintain it. You will need to earn 120 Continuing Professional Education (CPE) credits by your third-year anniversary. For details on earning and reporting CPEs, please consult the ISC2 Continuing Professional Education (CPE) Handbook (www.isc2.org/-/media/Project/ISC2/Main/Media/documents/members/CPE-Handbook-2023.pdf) and the CPE Opportunities page (www.isc2.org/members/cpe-opportunities). You will also be required to pay an annual maintenance fee (AMF) upon earning your certification and at each annual anniversary. For details on the AMF, please see the ISC2 CPE Handbook, www.isc2.org/Policies-Procedures/AMFs-Overview, and www.isc2.org/Policies-Procedures/Member-Policies.
Each chapter includes common elements to help you focus your studies and test your knowledge. Here are descriptions of those elements:
Tips and Notes Throughout each chapter you will see inserted statements that you should pay additional attention to. These items are often focused details related to the chapter section or related important material.
Summaries The summary is a brief review of the chapter to sum up what was covered.
Study Essentials The Study Essentials highlight topics that could appear on the exam in some form. This section reinforces significant concepts that are key to understanding the concepts and topics of the chapter. The Study Essentials point out specific knowledge you want to retain from a chapter.
Written Labs Each chapter includes written labs that synthesize various concepts and topics that appear in the chapter. These raise questions that are designed to help you put together various pieces you've encountered individually in the chapter and assemble them to propose or describe potential security strategies or solutions. We highly encourage you to write out your answers before viewing our suggested solutions in Appendix B.
Chapter Review Questions Each chapter includes practice questions that have been designed to measure your knowledge of key ideas that were discussed in the chapter. After you finish each chapter, answer the questions; if some of your answers are incorrect, it's an indication that you need to spend some more time studying the corresponding topics. The answers to the practice questions can be found in Appendix A.
Studying the material in the ISC2 CISSP: Certified Information Systems Security Professional Official Study Guide, Tenth Edition is an important part of preparing for the Certified Information Systems Security Professional (CISSP) certification exam, but we provide additional tools to help you prepare. The online Test Bank will help you understand the types of questions that will appear on the certification exam.
The sample tests in the Test Bank include all the questions in each chapter as well as the questions from the Assessment test in this Introduction section. In addition, there are four bonus practice exams that you can use to evaluate your understanding and identify areas that may require additional study. These four additional practice exams include 125 questions each and cover the breadth of domain topics in a similar percentage ratio as the real exam. They can be used as real exam simulations to evaluate your preparedness.
The online flashcards will push the limits of what you should know for the certification exam. The questions are provided in digital format. Each online flashcard has one question and one correct answer.
The downloadable PDF glossary is a searchable list of key terms from this exam guide that you should know for the CISSP certification exam.
A downloadble audio review is available where Mike Chapple reads aloud the Study Essentials from each chapter. You can listen to the audio review to keep your knowledge skills sharp as you go about your day. Its another means to sneak in a few more minutes of study time.
