Since 1994, security practitioners around the world have been pursuing a well-known and highly regarded professional credential: the Certified Information Systems Security Professional (CISSP) certification. And since 2001, CISSP For Dummies has been helping security practitioners enhance their security knowledge and earn the coveted CISSP certification.

Today, there are more than 120,000 CISSPs worldwide. Ironically, some certification skeptics might argue that the CISSP certification is becoming less relevant because so many people have earned the certification. However, the CISSP certification isnt less relevant because more people are attaining it more people are attaining it because its now more relevant than ever. Information security is far more important than at any time in the past, with extremely large-scale data security breaches and highly sophisticated cyberattacks becoming all too frequent occurrences in our modern era.

There are many excellent and reputable information security training and education programs available. In addition to technical and industry certifications, there are also many fully accredited postsecondary degree, certificate and apprenticeship programs available for information security practitioners. And there are certainly plenty of self-taught, highly skilled individuals working in the information security field who have a strong understanding of core security concepts, techniques and technologies.

But inevitably, there are also far too many charlatans who are all too willing to overstate their security qualifications and prey on the obliviousness of business and other leaders who think wiping a server, for example, means like, with a cloth or something in order to pursue a fulfilling career in the information security field, or perhaps for other more dubious purposes.

The CISSP certification is widely held as the professional standard for information security professionals. It enables security professionals to distinguish themselves from others in the information security field by validating both their knowledge and experience. Likewise, it enables businesses and other organizations to identify qualified information security professionals and verify the knowledge and experience of candidates for critical information security roles in their respective organizations. Thus, the CISSP certification is more relevant and important than ever before.

Some say that the Certified Information Systems Security Professional (CISSP) candidate requires a breadth of knowledge many miles across but only a few inches deep. To embellish on this statement, we believe that the CISSP candidate is more like the Great Wall of China, with a knowledge base extending over 3,500 miles maybe a few holes here and there, stronger in some areas than others, but nonetheless one of the Seven Wonders of the Modern World.

The problem with lots of currently available CISSP preparation materials is in defining how high (or deep) the Great Wall actually is: Some material overwhelms and intimidates CISSP candidates, leading them to believe that the wall is as high as it is long. Other study materials are perilously brief and shallow, giving the unsuspecting candidate a false sense of confidence while he or she merely attempts to step over the Great Wall, careful not to stub a toe. To help you avoid either misstep, CISSP For Dummies answers the question, What level of knowledge must a CISSP candidate possess to succeed on the CISSP exam?

Our goal in this book is simple: To help you prepare for and pass the CISSP examination so that you can join the ranks of respected certified security professionals who dutifully serve and protect organizations and industries around the world. Although weve stuffed it chock-full of good information, we dont expect that this book will be a weighty desktop reference on the shelf of every security professional although we certainly wouldnt object.
