This book gives a reasonably balanced review of the perception of security experts in regard to the level of computer or communications involved crime going on in our networked world. That is because this is not so much a book, as an extended compilation article. Power reproduces interviews with, or grabs quotations from the written works of, a great many forensic and security specialists or researchers. Very large chunks of the book are taken from previously published works.
Part one appears to be intended as a general introduction to computer related crime.
Chapter one is the usual statement that it goes on, mercifully brief. Despite an interview with Sarah Gordon and extensive quoting from Donn Parker, chapter two's look at cybercriminals focusses rather narrowly on the fact that people who do crimes aren't normal. Chapter four tries to look at costs. The title of part two seems to indicate a deeper analysis of criminals and system breakers. Three penetration episodes that led to the arrest of young crackers are described in chapter six.
