802.11 network terminology
Building upon the wireless fundamentals discussed in Chapter 1, Wireless Penetration Testing Fundamentals, there are a number of terms that will come into play during the scanning phase of the wireless assessment. When a wireless network is created, it will be identified by one or more topologies defined by the IEEE 802.11 workgroup. There are three basic network topologies defined by the IEEE 802.11 group. They are as follows:
- Basic Service Set (BSS)
- Extended Service Set (ESS)
- Independent Basic Service Set (IBSS)
Now, let's look at each of them in detail:
- BSS: This consists of one access point with one or more client stations attached to it. Client stations will communicate through the AP. The following figure shows the ...
