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 we’ve stuffed it chock-full of good information, we don’t expect that this book will be a weighty desktop reference on the shelf of every security professional — although we certainly wouldn’t object.
