Basics of packets :-
Packets could be divided broadly into three types :
These packets are further subdivided into multiple subtypes, we will look at the details of only those packets that we will be requiring more often for security perspective. However the reader is encouraged to go through the details of each of these packets and their subtypes given in the 802.11 standard specifications by IEEE.
In order to gain more practical knowledge we would first see a basic sniffing attack and then will analyze the underlying concepts. To make the text more relevant we will learn new concepts that were not mentioned above.
