Any opinions I’ve expressed and any deficiencies found in this book are mine, and mine alone.

Thanks to all my colleagues and clients who I have been honored to work with—without you all this book would have never have found its way to life.


This book is dedicated to the following:

My loving parents, thank you for your many words of wisdom, hopefully you have a better idea of what I do now.

My understanding wife, thank you for letting me follow my dreams.

My wider relatives/friends, please find someone else to clean those viruses off your machines.

Finally, a big thank you to the unnamed that are fighting the fight to protect our countries/citizens from the badness that is out there.
