For all of you who struggle
to make the digital world more secure,
this one’s for you.
—Roberta Bragg

This book is dedicated to my wife
Marjorie and my son Trent,
both of whom were very helpful
and supportive during the two years
of intense effort required of me to produce
a work of this magnitude.
—Mark Rhodes-Ousley

To Nancy, whose love and support
made this all possible.
There aren’t words for what you mean to me.
And also to my family and friends—
you still mean the world to me.
—Keith Strassberg
