About Book: 

     Purpose of this Book

         Computer security as a discipline was first studied in the early 1970s; today the discipline has evolved into a vital yet highly complex domain. This book is about understanding and applying in practice this domain if Information Systems Security as well as its management issues and challenges. This book also addresses privacy concepts in recognition of the ever-growing importance of data privacy. The aim of the book is to create security and privacy awareness among students and researchers as well as to sensitize industry practitioners to the importance of security and privacy. This is so because information security is perhaps not fully understood in practice owing to its complex and dynamically changing nature, Not surprisingly, very few organizations have integrated security policies, measures and technologies to protect their information assets against internal and external threats. The need to underscore the importance of security as a business issue cannot be overemphasized.
