Networking & Protocols for Attackers

What you'll learn

You can't attack what you can't map. This Edge gives you the networking vocabulary every red teamer relies on:

• IP addresses, subnets, and ports, and where they sit in the OSI model — from an attacker's point of view
• The difference between TCP and UDP and how the TCP 3-way handshake works
• The key protocols and their default ports you'll see constantly (HTTP, HTTPS, SSH, DNS, SMB, RDP)
• How to inspect a host's own listening services and addresses with ss and ip

Prerequisites

The "Linux Command Line for Hackers" Edge is helpful but not required. No prior networking knowledge assumed. Answer the questions from the lesson content.
