CISSP in 21 Days - Second Edition

Book Description

Boost your confidence and get the competitive edge you need to crack the exam in just 21 days!

About This Book

  • Day-by-day plan to study and assimilate core concepts from CISSP CBK
  • Revise and take a mock test at the end of every four chapters
  • A systematic study and revision of myriad concepts to help you crack the CISSP examination

Who This Book Is For

If you are a Networking professional aspiring to take the CISSP examination and obtain the coveted CISSP certification (considered to be the Gold Standard in Information Security personal certification), then this is the book you want.

This book assumes that you already have sufficient knowledge in all 10 domains of the CISSP CBK by way of work experience and knowledge gained from other study books.

What You Will Learn

  • Review Exam Cram and Practice review questions to reinforce the required concepts
  • Follow the day–by-day plan to revise important concepts a month before the CISSP® exam
  • Boost your time management for the exam by attempting the mock question paper
  • Develop a structured study plan for all 10 CISSP® domains
  • Build your understanding of myriad concepts in the Information Security domain
  • Practice the full-blown mock test to evaluate your knowledge and exam preparation

In Detail

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.

Style and approach

There are many overlapping concepts that are applicable to more than one security domain in the CISSP exam. Hence, the eight security domains are aligned in a logical order so as to cover the concepts in the most appropriate sequence in this guide. Each chapter provides an illustration in the form of a flow diagram at the start to supply an overall view of the concepts covered in that chapter. This will facilitate a bird's-eye view of the chapter contents and the core security concepts covered. You can refer to this book throughout while preparing for the test or most importantly systematically revise the eight domains on a day-by-day basis up to one month before the exam. Hence the chapters are divided into 21 convenient days.
