Cybercrime is exploding. According to the FBI, Americans lost more than $20 billion to cybercrime in 2025. In 2015, it was just over $1 billion. A near 20-fold increase in just a decade. And there’s no sign that the growth is slowing down, as the tools available to criminals get more and more powerful each year. Most books about cybersecurity are written for an audience of IT professionals. This one isn't. This book is written for individuals and families who want to keep themselves and their loved ones safe. This book focuses on the small number of policies that make the biggest difference, in the same way a good financial plan focuses on a few decisions that matter, not hundreds that don't. In this book, you'll learn: Why passkeys and physical security keys are the biggest security upgrade most households haven't made yet. How to choose and safely use a password manager (and why "just remember your passwords" quietly stopped working years ago). The account settings, device habits, and network policies that actually reduce risk (and the ones that don't). How to build a personal household security checklist, so good habits don't get abandoned. What to do if the worst happens: a clear, step-by-step response plan. How to help aging parents or other vulnerable loved ones, as well as a research finding that may surprise you about when to start. Nobody is 100% fraud-proof. This book won't promise otherwise. But the person who accepts that, and puts a few smart layers of protection in place, is far safer than the person who's simply confident it won't happen to them.
