dc.description.abstract | I would like to thank all the people who work in the information security industry who
are driven by their passion, dedication, and a true sense of doing right. These selfless
professionals sacrifice their personal time to prevent, block, and respond to the relent-
less efforts of malicious actors around the world. We all sleep more peacefully at night
because you remain at the ready.
In this ninth edition, I would also like to thank the following:
• Ronald C. Dodge, Jr., who introduced me to Shon Harris and, in so doing,
started me off on one of the best adventures of my life
• Kathy Conlon, who, more than anyone else, set the conditions that led to nine
editions of this book
• Carol Remicci
• David Harris
• The men and women of our armed forces, who selflessly defend our way of life | vi |
