Preface
This book attempts to take a novel approach to the presentation and understanding of a controversial
topic in modern-day society: hacking versus cracking.The perception of this bi-modal activity is as
controversial as the process itself—with many in society confusing the positive attributes of hackers
with the criminal activities of crackers.This dictionary tries to balance the two sides of the equation:
the White Hat or the positive side of hacking with the Black Hat or the negative side of cracking.
This dictionary is written for general readers, students who want to learn about hackers and crackers, and business leaders who want to become more knowledgeable about the IT security field to keep
their enterprises financially stable and to be proactive against intrusive cyber-attackers.
For those wanting to learn beyond our entries (which have been grouped into general terms, legal
terms, legal cases, and person), we have provided further readings under each entry and at the end of
the dictionary.The entries have been compiled by two experts in the field of information technology
security and hacker profiling. Hundreds of entries have been included to provide explanations and
descriptions of key information technology security concepts, organizations, case studies, laws, theories, and tools. These entries describe hacktivist, creative hacker, and criminal cracker activities
associated with a wide range of cyber exploits.
Although we acknowledge that we cannot include every item of significance to the topics of hacking and cracking in a one-volume reference book on this intriguing topic, we have attempted to be
as comprehensive as possible, given space limitations.Though we have focused on the past 35 years in
particular, we note that the foundations of hacking and cracking existed at the commencement of
computer innovations in the earlier parts of the previous century.
