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.

Cryptanalytic attacks

Cryptanalytic attacks mean compromising keys by way of decipherment to find out the keys. The goal of cryptanalysis is to decipher the private or secret key. The amount of information provided to the analyst as well as the type of information provided determines the type of attacks possible.

The methods of cryptanalytic attacks

The following six are the possible attack scenarios. Candidates are advised to understand the key differences between the different types of attacks:

  • The cipher text only attack: This refers to the availability of the cipher text (encrypted text) to the cryptanalyst. With large cipher text data, it maybe possible to decipher the cipher text by analyzing the pattern.

  • The known-plain text attack: When a cryptanalyst obtains cipher text as well as the corresponding plain text, then this type of attack is known as the known-plaintext attack. In this scenario, even if the data is small, it is possible to understand the algorithm.

  • The chosen-plain text...
