Chapter 6. Analyzing Traffic in Thin Air
In this chapter, you will learn how to analyze wireless traffic and pinpoint any problems. You will also learn how to analyze wireless traffic using Wireshark. The following are the topics we will cover in this chapter:
- Understanding IEEE 802.11 traffic
- Analyzing normal and unusual behavior
- Lab up—wireless communication
- Decrypting encrypted wireless traffic
- Lab up—decrypting WEP and WPA traffic
- Practice questions
We start from the basics such as how WLAN traffic gets generated and various essential elements responsible for handling the wireless transmission between hosts. Then, moving ahead, we will analyze the usual and unusual forms of packets that can be seen in Wireshark. Side by side, we will identify anomalies and regular traffic patterns. We will also discuss how you can decrypt wireless (WEP) traffic using Wireshark, which can definitely give an advantage while auditing WLAN environment.
What we are going to witness is not...
