Cybersecurity Fundamentals Explained
The issue of Cybersecurity is of paramount importance in the digital age. With near-continuous revelations about incidents and breaches in the media, organizations and individuals are faced with the challenge of finding the balance between risk, innovation, and cost. At the same time, the field of cyber security is undergoing dramatic changes, demanding that organizations embrace new practices and skill sets. In this book, I will explore the basics of Cybersecurity and discuss how ordinary people and organizations can best ensure the safety and security of their data. By examining numerous studies, reports, and surveys, I will argue that organizations must embrace a comprehensive approach to cyber security that considers the ever-changing nature of the threat landscape. In the following chapters, I will first explain the fundamentals of cyber security, and then discuss several case studies on the more prominent security breaches in the last few years to show what can happen to a business.
