Overview of this book

Certified Information Systems Security Professional (CISSP) is an internationally recognized and coveted qualification. Success in this respected exam opens the door to your dream job as a security expert with an eye-catching salary. But passing the final exam is challenging. Every year a lot of candidates do not prepare sufficiently for the examination, and fail at the final stage. This happens when they cover everything but do not revise properly and hence lack confidence. This simple yet informative book will take you through the final weeks before the exam with a day-by-day plan covering all of the exam topics. It will build your confidence and enable you to crack the Gold Standard exam, knowing that you have done all you can to prepare for the big day. This book provides concise explanations of important concepts in all 10 domains of the CISSP Common Body of Knowledge (CBK). Starting with Confidentiality, Integrity, and Availability, you will focus on classifying information and supporting assets. You will understand data handling requirements for sensitive information before gradually moving on to using secure design principles while implementing and managing engineering processes. You will understand the application of cryptography in communication security and prevent or mitigate strategies for network attacks. You will also learn security control requirements and how to assess their effectiveness. Finally, you will explore advanced topics such as automated and manual test result analysis and reporting methods. A complete mock test is included at the end to evaluate whether you're ready for the exam. This book is not a replacement for full study guides; instead, it builds on and reemphasizes concepts learned from them.

Preface

Preface

Certified Information System Security Professional (CISSP) is a coveted certification for an information security professional to achieve. Certified individuals are considered experienced and knowledgeable information security professionals. This is due to the fact that the certification's requirements are that the candidate not only has to pass the exam, but have 4 to 5 years of relevant practical experience in one or two domains of information security.

The exam is conducted by the International Information System Security Certification Consortium (ISC)²®, a nonprofit consortium that is the globally recognized Gold Standard for certifying information security professionals throughout their careers. (ISC)²® was founded in 1989 by industry leaders and has certified over 1,00,000 information security professionals across the globe.

While preparing for CISSP™, a candidate has to study many books and references. There are many books that cover the CISSP™ CBK™ domains in depth and provide a starting point for a thorough preparation for the exam. References to such books are covered in the references chapter at the end of this book. However, since there are many concepts spread across the eight security domains, it is an important starting point as a guide to explore deeper concepts, as well as refresh many concepts that need to be revised before the exam. This book addresses the requirements of the initial preparation for the exam, as well as revisiting the key concepts in these eight domains. To facilitate such a need core concept, the eight CISSP information security domains are explained in a short, simple, and lucid form.

What this book covers

Chapter 1, Day 1 – Security and Risk Management - Security, Compliance, and Policies, covers the foundational concepts in information security, such as Confidentiality, Integrity, and Availability (CIA) from the first domain of CISSP Common Body of Knowledge (CBK)®.

Chapter 2, Day2 – Security and Risk Management - Risk Management, Business Continuity, and Security Education, covers risk management practices that include the identification of risks through risk analysis and assessment, and mitigation techniques such as reduction, moving, transferring, and avoiding risks. An overview of business continuity requirements, developing and documenting project scopes and plans, and conducting business impact analyses is provided. Further more policies and practices pertaining to personnel security are covered.

Chapter 3, Day 3 – Asset Security - Information and Asset Classification, covers the classification of information and supporting assets; the collection of information, its handling and protection throughout its lifecycle, and ownership of information and its privacy; and data retention requirements and methods.

Chapter 4, Day 4 – Asset Security - Data Security Controls and Handling, covers data security controls that include Data Loss Prevention strategies, such as data at rest, data in transit, data in use, and data handling requirements for sensitive information.

Chapter 5, Day 5 – Exam Cram and Practice Questions, covers important concepts and information from the first two domains of the CISSP CBK, namely Security and Risk Management and Asset Security. They are provided in an exam-cram format for fast review and serve to reinforce of the two domains covered in the previous four chapters.

Chapter 6, Day 6 – Security Engineering - Security Design, Practices, Models, and Vulnerability Mitigation, covers concepts for using secure design principles while implementing and managing engineering processes. Information security models and system security evaluation models with controls and countermeasures, and security capabilities in information systems, are also covered. Also, vulnerability assessment and mitigation strategies in information systems, web-based systems, mobile systems, and embedded and cyber-physical systems are covered in detail.

Chapter 7, Day 7 – Security Engineering - Cryptography, covers the application of cryptography in information security requirements. Various concepts such as the cryptographic life cycle, types of cryptography, public key infrastructure, and so on are covered with illustrations. The methods of cryptanalytic attack are covered in detail with suitable examples.
