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!
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.
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.
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.
