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

An overview of cryptography


Sensitive assets need protection from unauthorized disclosure or tampering. The sensitivity of assets is determined by confidentiality and integrity requirements and the impact of compromise on the corporation or national security. Cryptographic methods and solutions provide assurance to protect assets from compromise.

Observe the following illustration:

The following bullet points represent a brief overview of the preceding diagram. These points explain the overall structure of this chapter in a logical sequence:

  • Sensitive assets require an additional level of security pertaining to confidentiality and integrity.

  • Additional security requirements of confidentiality and integrity can be assured through the application of cryptographic methods.

  • The fundamentals of cryptography are related to encryption and the methods of encryption.

  • Various types of encryption methods are used in the cryptography domain based on their characteristics, such as the type of algorithm used...
