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

Applications and the use of cryptography


Cryptographic systems are the common implementations of standard algorithms. They may be used in applications and embedded systems.

The following are some systems that are popular:

  • Transport Layer Security (TLS) and its predecessor Secure Sockets Layer (SSL) are protocols that provide communication security by encrypting sessions while using the Internet. They use many of the cryptographic algorithms discussed previously. Some of the activities that can be secured by TLS or SSL are web browsing, e-commerce transactions such as online shopping, banking, and more, and instant messaging or Internet chat.

  • Secure Electronic Transaction (SET) is a set of standard protocols for securing credit card transactions over insecure networks. SET uses digital certificates and public key cryptography. One of the primary applications is to ensure security while using credit cards over the Internet.

  • IPSec is a set of protocols to secure Internet communication. Authentication...
