Networking is the foundation of every hack. If you don't understand how data moves across a network, you can't find where it breaks and that's exactly what this episode covers. We go deep into the protocols, tools, and concepts that every ethical hacker needs to understand before touching anything else. Everything in this series is for legal, ethical use only.
