Challenge
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Challenge
MAC Addressing
In this challenge you will be analyzing media access control (MAC) addresses and learning how they can be spoofed within a network.
Challenge
Address Resolution Protocol (ARP)
This challenge will have you exploring the Address Resolution Protocol (ARP), analyzing ARP broadcasts, and taking a look at an ARP storm.
Challenge
Exploring IPv4 in Malicious Traffic
With IPv4, you will detect anomalies by inspecting the Time to Live (TTL) field within the IP header. This challenge makes use of a Man in the Middle (MiTM) attack.
