      Welcome to the (ISC)²® CISSP® Certified Information Systems Security Professional Official Study Guide, 9th Edition.

      Data from the 2020 Cybersecurity Workforce Study shows that 47 percent of employers require their security staff to hold vendor-neutral cybersecurity certifications and that the Certified Information Systems Security Professional (CISSP) is the most commonly held.

      According to the study, employers value certified cybersecurity professionals for a number of qualities, from having increased confidence in strategies and practices to communicating and demonstrating that confidence and competence to customers. Other benefits of certification cited by employers include reducing the impact of a security breach, knowing that technology and best practices are up to date, and enhancing the organization's reputation within its given industry.

      In addition to engendering confidence on the part of their employers and organizations, security professionals with cybersecurity certifications can boost their salaries by 27 percent on average. There has never been a better time to use your information technology skills to help protect your organization's infrastructure, information, systems, and processes and to improve and grow in your professional journey.

      The CISSP certification is the gold standard for mastery in the field of cybersecurity, demonstrating to employers that you have strong knowledge and skills within a broad range of cybersecurity disciplines and an ability to build and manage nearly all aspects of an organization's security operations. It also signals your commitment to ongoing professional development as you continue to stay abreast of industry changes and sharpen your skills.

      This study guide will steer you through the eight subject area domains on which the CISSP exam will test your knowledge. Step by step, it will cover the fundamentals involved in each topic and gradually build toward more focused areas of learning to prepare you, based on the content covered in the (ISC)² CISSP Common Body of Knowledge (CBK).

      As you prepare to sit for the CISSP exam, this guide will help you build a solid understanding of concepts of design, implementation, and management of best-in-class cybersecurity programs, as well as the ethical fidelity required of CISSP holders.

      I hope that you will find the (ISC)²® CISSP® Certified Information Systems Security Professional Official Study Guide 9th Edition helpful in your cybersecurity journey, exam preparation, and continued professional growth.

      Sincerely,

      An illustration of the signature of Clar Rosso.

      Clar Rosso

      CEO, (ISC)²

      Introduction

      The (ISC)2® CISSP®: Certified Information Systems Security Professional Official Study Guide, Ninth 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 study guide are for you. The purpose of this book is to adequately prepare you to take the CISSP exam.

      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 full-time paid work experience (or four years if you have a college degree) in two or more of the eight domains covered by the CISSP exam. If you are qualified to take the CISSP exam according to (ISC)², then you are sufficiently prepared to use this book to study for it. For more information on (ISC)², see the next section.

      (ISC)² also allows for a one-year reduction of the five-year experience requirement if you have earned one of the approved certifications from the (ISC)² prerequisite pathway. These include certifications such as Certified Authorization Professional (CAP), Certified Information Security Manager (CISM), Certified Information Systems Auditor (CISA), Cisco Certified Internetwork Expert (CCIE), Cisco Certified Network Associate Security (CCNA Security), CompTIA Advanced Security Practitioner (CASP), CompTIA Security+, CompTIA Cybersecurity Analyst (CySA+), and many of the Global Information Assurance Certification (GIAC) certifications. For a complete list of qualifying certifications, visit www.isc2.org/Certifications/CISSP/Prerequisite-Pathway.

      none

      You can use only one of the experience reduction measures, either a college degree or a certification, not both.

      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.

      (ISC)²

      The CISSP exam is governed by the International Information Systems Security Certification Consortium (ISC)². (ISC)² is a global nonprofit organization. It has four primary mission goals:

      Maintain the Common Body of Knowledge (CBK) for the field of information systems security.

      Provide certification for information systems security professionals and practitioners.

      Conduct certification training and administer the certification exams.

      Oversee the ongoing accreditation of qualified certification candidates through continued education.

      (ISC)² is operated by a board of directors elected from the ranks of its certified practitioners.

      (ISC)² supports and provides a wide variety of certifications, including CISSP, CISSP-ISSAP, CISSP-ISSMP, CISSP-ISSEP, SSCP, CAP, CSSLP, HCISPP, and CCSP. These certifications are designed to verify the knowledge and skills of IT security professionals across all industries. You can obtain more information about (ISC)² and its other certifications from its website at isc2.org.

      The CISSP credential is for security professionals responsible for designing and maintaining security infrastructure within an organization.

      Topical Domains

      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.

      Prequalifications

      (ISC)² 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’ full-time paid work experience or with four years’ experience and a recent IT or IS degree or an approved security certification (see isc2.org for details). Professional experience is defined as security work performed for salary or commission within two or more of the eight CBK domains.

      Second, you must agree to adhere to a formal code of ethics. The CISSP Code of Ethics is a set of guidelines (ISC)² wants all CISSP candidates to follow to maintain professionalism in the field of information systems security. You can find it in the Information section on the (ISC)² website at isc2.org.

      (ISC)² also offers an entry program known as an Associate of (ISC)². This program allows someone without any or enough experience to qualify as a CISSP 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 and a résumé, can the individual be awarded CISSP certification.

      Overview of the CISSP Exam

      The CISSP exam focuses on security from a 30,000-foot view; 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 (ISC)² calls CISSP-CAT (Computerized Adaptive Testing). For complete details of this new version of exam presentation, please see www.isc2.org/certifications/CISSP/CISSP-CAT.

      The CISSP-CAT exam will have a minimum of 100 questions and a maximum of 150. Not all items you are presented with count toward your score or passing status. These unscored items are called pretest questions by (ISC)², whereas the scored items 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., pretest 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.

      The CISSP-CAT grants a maximum of three 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.

      The CISSP-CAT does not have a published or set score to achieve. Instead, you must demonstrate the ability to answer above the (ISC)² bar for passing, called the passing standard (which is not disclosed), within the last 75 operational items (i.e., questions).

      If the computer determines that you have a less than 5 percent chance of achieving a passing standard and you have seen 75 operational items (which will be at question 100), your test will automatically end with a failure. If the computer determines that you have a higher than 95 percent chance of achieving or maintaining a passing standard once you have seen 75 operational items (which will be at question 100), your test will automatically end with a pass. If neither of these extremes is met, then you will see another question, and your status will be evaluated again after it is answered. You are not guaranteed to see any more questions than are necessary for the computer grading system to determine with 95 percent confidence your ability to achieve a passing standard or to fail to meet the passing standard. If you do not achieve the passing standard 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.

      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 was updated in October 2020; you can read the official policy here: www.isc2.org/Exams/After-Your-Exam.

      You will need to pay full price for each additional exam attempt.

      It is not possible to take the previous English paper-based or CBT (computer-based testing) flat 250-question version of the exam. CISSP is now available only in the CBT CISSP-CAT format in English through (ISC)²-authorized Pearson VUE test centers in authorized markets.

      none

      In early 2021, (ISC)² via Pearson Vue performed an online exam proctoring pilot for CISSP. The results of this pilot will be evaluated by Q3 2021 and a decision on how to proceed will be made by (ISC)² based on those results at that time. Keep an eye on the (ISC)² blog for updated information about online proctored remote CISSP exam offerings.

      The CISSP exam is available in English, French, German, Brazilian Portuguese, Spanish (Modern), Japanese, Simplified Chinese, and Korean. These non-English versions of CISSP are still administered using the 250-question linear, fixed-form, flat exam.

      For more details and the most up-to-date information on the CISSP exam direct from (ISC)², please visit www.isc2.org/Certifications/CISSP and download the CISSP Ultimate Guide and the CISSP Exam Outline (currently located in the 2: Register and Prepare for the Exam section). You might also find useful information on the (ISC)² blog at blog.isc2.org/isc2_blog. For example, there is a good article posted in October 2020 titled Why Does the CISSP Exam Change? (blog.isc2.org/isc2_blog/2020/10/why-does-the-cissp-exam-change.html).

      CISSP Exam Question Types

      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 (ISC)² 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.

      Advice on Taking the Exam

      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 no longer allowed on the CISSP exam, 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. 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.

      Also note that (ISC)² 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, then read the answer options, and then reread the question.

      Eliminate wrong answers before selecting the correct one.

      Watch for double negatives.

      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, (ISC)² exam policies are subject to change. Please be sure to check isc2.org for the current policies before you register and take the exam.

      Study and Exam Preparation Tips

      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 and work through its review material.

      Answer all the review questions and take the practice exams provided in the book and/or in the online test engine. Be sure to research each question that you get wrong in order to learn what you didn't know.

      Complete the written labs from each chapter.

      Read and understand the Exam Essentials.

      Review the (ISC)²'s Exam Outline: isc2.org.

      Use the flashcards included with the study tools to reinforce your understanding of concepts.

      none

      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 (ISC)² CISSP Certified Information Systems Security Professional Official Practice Tests, 3rd Edition (ISBN: 978-1-119-47592-7). 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.

      Completing the Certification Process

      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 is a CISSP, or other (ISC)² certification holder, in good standing and familiar with your work history to submit an endorsement form on your behalf. Once you pass the CISSP exam, you will receive an email with instructions. However, you can review the endorsement application process at www.isc2.org/Endorsement.

      If you registered for CISSP, then you must complete endorsement within nine months of your exam. If you registered for Associate of (ISC)², then you have six years from your exam data to complete endorsement. Once (ISC)² accepts your endorsement, the certification process will be completed and you will be sent a welcome packet.

      Once you have achieved your CISSP certification, you must now work toward maintaining the certification. 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 (ISC)² Continuing Professional Education (CPE) Handbook (www.isc2.org/-/media/ISC2/Certifications/CPE/CPE---Handbook.ashx) and the CPE Opportunities page (www.isc2.org/Membership/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 (ISC)² CPE Handbook and www.isc2.org/Policies-Procedures/Member-Policies.
