alike, coupled with the invention of mobile devices and wireless networking, have ushered in an Information Revolution that has impacted just about every aspect of human existence.

      Humanity’s reliance on technology, however, has also created enormous risks. It seems that not a day goes by without some new story emerging of a data breach, cyberattack, or the like. Simultaneously, because society’s reliance on technology increases on a daily basis, the potential adverse consequences of cyberattacks have grown exponentially to the point that people can now lose their fortunes, their reputations, their health, or even their lives, as the result of cyberattacks.

      In fact, since the publication of the first edition of this book, Americans have seen cyberattacks cause fuel shortages, spikes in meat prices, financial losses, and even death. And societal changes resulting from the COVID-19 pandemic — including the dramatic increase in the number of people who, at least sometimes, leverage computers and computer networks in order to work remotely — have upped the stakes even more. While people all around the developed world outsource a large portion of their national security to their countries’ respective armed forces, their fire safety to trained fire departments, and their protection from criminals to law enforcement agencies, ensuring that one remains safe from cyber threats requires far more personal involvement.

      It is no wonder, therefore, that people living in the modern world understand the need to protect themselves from cyber-dangers. This book shows you how to do so.

      While many books have been written over the past couple decades on a wide variety of cybersecurity-related topics, most of them don’t provide the general population with the information needed to properly protect themselves.

      I wrote Cybersecurity For Dummies to provide people who do not work as cybersecurity professionals with a foundational book that can teach them what they need to know about cybersecurity and explain why they need to know it. This book offers you practical, clear, and straightforward advice that you can easily translate into actions that can help keep you and your children, parents, and small businesses cybersecure. The second edition of this book contains updates to help people understand and address cybersecurity risks created by changes to our world in terms of technological advances, societal changes, and new geopolitical realities.

      Cybersecurity For Dummies is divided into several parts. Parts 1, 2, and 3 provide an overview of cybersecurity and give tips on protecting yourself and your loved ones from both external threats and from making dangerous (and potentially disastrous) mistakes. Topics such as how to secure your online accounts, how to select and protect passwords, and how to safely work remotely fall into these parts of the book.

      Part 4 offers tips on securing small businesses, which may be especially pertinent for small business owners and employees. Part 4 then also discusses some of the unique security needs that face firms as they grow larger and touches on cybersecurity-in-government related matters.

      Part 5 shows you how to identify security breaches. Part 6 covers the process of backing up, something that you should do proactively before the need to recover arises, as well as how to recover from security breaches.

      Part 8 gives several lists of ten items that you may want to keep as tip sheets.

      Please keep in mind that while internalizing all the information in this book, and putting it into practice, will likely dramatically improve your cybersecurity posture, reading this book will no more make you an expert in cybersecurity than reading a book on the workings of the human heart will quickly transform you into a competent cardiologist.

      Cybersecurity is a complex, rapidly changing field whose professionals spend years, if not decades, studying and working full-time to develop, sharpen, and maintain the skills and expertise that they utilize on a constant basis. As such, please do not consider the advice within this book as a substitute for hiring a professional for any situation that reasonably warrants the latter.

      Also, please keep in mind that technical products change quite often, so any screenshots included within the book may not be identical to the screens that you observe when you perform similar actions to those described in the text. Remember: Cybersecurity threats are constantly evolving, as are the technologies and approaches utilized to combat them.

      In this book, I make some assumptions about your experience with technology:

       You have experience with using a keyboard and pointer, such as a mouse, on either a Mac or Windows PC and have access to one of those machines.

       You have experience with using a so-called “smartphone” running the Android or iOS operating systems.You know how to use an Internet browser, such as Firefox, Chrome, Edge, Opera, or Safari.

       You know how to install applications on your computer and have adequate rights to do so.

       You know how to perform a Google search.

      Throughout this book, small images, known as icons, appear in the margins. These icons mark important tidbits of information:

      

The Tip icon identifies places where I offer additional tips for making this journey more interesting or clear. Tips cover some neat shortcuts that you may not have known about.

      

The Remember icon bookmarks important points that you'll want to keep in mind.

      

The Warning icon helps protect you from common errors and may even
