Foreword Cyberspace is vital to human progress in the 21st century. Networked computing and the digital devices that provide us access enable the ingenuity of the human mind to expand our understanding of the world in which we live and make it more comfortable and more engaging for more of the world’s population. The vitality that flows in and through cyberspace, however, is challenged by an inherent vulnerability that enables, simultaneously, misuse in the form of unauthorized access to systems, software, and computer hardware. The goal of cybersecurity is to ensure that the vitality of cyberspace is not overwhelmed by its vulnerabilities. The title of this volume reveals how we can achieve this positive outcome. The author has asked the reader not to be a passive absorber of information but rather a partner in a common effort. This is the difference between an introduction to something and an invitation to participate in a way of doing things. Professor Hamman has done the reader a great service in inviting us to do our part to actively reduce cyber insecurity in our roles as individuals, individuals who work in organizations, and individuals who come together nationally and even internationally, since cyberspace is both ubiquitous in our lives and global in its reach. His invitation is grounded on fundamentals rather than pure technical details or contemporary examples that, given the nature of cyberspace, will be fleeting. To contribute as a partner in cybersecurity, we all do not need to be technical experts, but we do need a base understanding of how to operate our digital technology responsibly, ethically, safely, and securely. I do not need to know how to build a car in order to drive it, but I do need to know how to fuel it, how to maintain its basic functions (put air in tires and change my oil) and how to turn it on and get it to propel me to where I want to go (of course in a few years, computers will handle this driving for me and I’ll need to know something about my algorithm-chauffeur). But society does also need those who know how to build the car itself and mechanics who can handle the most complex of car system updates and repairs. So too in cybersecurity. We need more cyber aware citizens and more cyber ninjas. This volume will help produce both. For those seeking cyber awareness, this volume is accessible and, again, inviting. You will be ready to contribute to more security. For those seeking cyber expertise, this volume will deepen your thinking, excite your interests, and drive you to learn more. Accept the invitation to cybersecurity and we all will benefit from a more secure digital world. Professor Richard J. Harknett
