With the help of the Internet, our personal information is everywhere. Our banking and financial information is online, along with our medical records and social media profiles. Privacy is becoming a bigger issue now that we share our personal information for more things, more frequently. “Protect Yourself Online” by Matthew Danda is a great starting point for learning how to be a more informed user of the Internet and how to be more aware of our personal information. The book is structured in four parts: Part 1 discusses the fundamentals of Internet security and privacy, Part 2 specializes in privacy on the World Wide Web, the topics of Part 3 are email security and privacy, and Part 4 discusses the ways in which to protect a computer.

Explain that threats can affect a person's computer, property, or personal safety. It also highlights the fact that some threats can go unnoticed. Danda uses this opening chapter to shed light on ideas that readers may not have considered. In Chapter 2, Danda describes the basics of the Internet.

Computers send information over the Internet by breaking the information into packets and sending the packets separately (Danda
