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

Security policies, standards, procedures, and guidelines


Policies, standards, procedures, and guidelines form a quartet of organizational mechanisms in protecting information:

  • Security policies are high-level statements that provide management intent and direction for information security. They describe the what of the description.

  • Security standards provide prescriptive statements, control objectives, and controls for enforcing security policies. In a way, they provide the how of the description. They can be internally developed by the organization and/or published by standard bodies, such as National Institute of Standards and Technology (NIST), International Organization for Standardization (ISO), or country-specific standard bodies.

  • Security procedures are step-by-step instructions to implement the policies and standards.

  • Security guidelines provide the best practice methods to support security controls selection and implementation. They can be used in whole or part while implementing security standards.

    For example, NIST Special Publication 800-14, Generally Accepted Principles and Practices for Securing Information Technology Systems provides procedures and guidelines for System security life cycle.

International Organization for Standardization (ISO) along with International Electro-Technical Commission (IEC) has published code of practice guidelines and a standard for Information Security Management System (ISMS). They are as follows:

  • ISO/IEC 27002: Code of practice for information security. This standard provides a list of best practices an organization could adopt for security management.

  • ISO/IEC 27001: This standard specifies the management framework required for Information Security and is a certifiable standard. Organizations can seek certification against this standard for their Information Security Management System (ISMS).
