In the early XXI century, I was known as the "queen of OSINT (Open-Source Information Intelligence)." I figured out how to find anything and anybody who had left a digital footprint. I put Johnny Long's techniques on steroids. I developed courses to teach my skills to law enforcement agencies, private sector, and the U.S. Navy SEALs.
One of those courses is about cyber defense. It is about securing your own cyber perimeter, and protecting your data. It is the course you are about to read on these pages. It is written to be comprehended by everybody with easy to follow step-by-step instructions.
The goal of this book is to help you reach a low level of risk by using a combination of technology and behavior modification. Now, it is up to you to accept my advice line by line or pick and choose.
Cyber security is each one of us responsibility. I urge you to do your part.
