Wireless network topologies
In this section, we will discuss various types of wireless network topologies. Before attacking a wireless network, a penetration tester should have an understanding of wireless network designs and how clients are interconnected.
Independent Basic Service Set
Within an Independent Basic Service Set (IBSS), there are no APs or wireless routers in this design/topology. Each client device establishes a connection with the others over the IEEE 802.11 standard. This is known as an ad hoc network:
Basic Service Set
In a Basic Server Set (BSS) design, all clients are interconnected with the use of a wireless router or an AP. The wireless router or AP is responsible for moving network traffic between clients and the wired network. This type of topology is also known as infrastructure mode:
Extended Service Set
The Extended Service Set (ESS) mode is very similar to BSS. Within an ESS, there are multiple APs or wireless routers connected to the same wired network. This design...
