Description: Welcome to Part 5 of the WLAN Security Megaprimer! Please start this series by watching Part 1 http://www.securitytube.net/video/1756, if you have not done so already.
In this video, we will dive deep into WLAN Header fields - Frame Control, Duration/ID, BSSID, SA, TA, DA, Sequence Control, QoS control, Frame Body, FCS etc. We will also look at an in-depth introduction into the bit fields in Frame Control which include - type, subtype, to ds, from ds, more fragments, retry, power management, more data, protected frame etc.
Though I will be using Wireshark to help you understand these header fields, I do not deny that this video is a bit theoretical and long :) but I would really encourage you to go through this as it will give you a firm grounding in WLAN protocol basics. This is a must for future videos when we will discuss various attacks.
As always, your comments keep me going, so please keep them coming :)
