Network Protocols for Security: TCP and UDP
In this lab, you'll practice creating network traffic and inspecting transport protocols. When you're finished, you'll have a fundamental understanding on how to find anomalies within TCP and UDP.
Terms and conditions apply.
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
Creating Normal Network Traffic
You will be creating normal network traffic by browsing to a web page, then analyze that traffic to gain an understanding on how transport protocols function.
Challenge
Inspecting TCP Flags and Ports
For this next challenge, you will be using tcpdump, a command-line tool for capturing and analyzing PCAP. Here you will be inspecting TCP flags which are methods to indicate a particular connection state.
Challenge
Exploring TCP Flags in Malicious Traffic
This next challenge will involve you analyzing a known-malicious set of network traffic containing a scan of the internal network.
Challenge
The Last Challenge
The last challenge of this lab and your last chance to experience the environment before clicking Next and ending this small little world that flittered into existence just for you.
Provided environment for hands-on practice
We will provide the credentials and environment necessary for you to practice right within your browser.
