See what an attacker sees about you — first.

Before anyone attacks a system, they quietly study it from the outside. This book teaches you to do the very same to your OWN systems — safely and lawfully — so you can find and fix what you are accidentally showing the world. You will finally understand how the internet really works (as a simple postal system), then learn the complete passive-reconnaissance toolkit — whois, DNS, OSINT, theHarvester and more — used only ever on what is yours, touching nothing that isn't.

WHAT YOU'LL LEARN:
• How the internet moves your data: IP addresses, ports, DNS, packets and routers
• How to footprint your own domain exactly the way an attacker would
• How to uncover and reduce your public exposure — touching nothing that isn't yours
• Every tool explained in plain words, each with a Guided Practice
