Chapter 4. Breaching Wireless Security

In this chapter, we will discuss how hackers attack and breach wireless security. We do this to understand the various methods of attacking so that we can defend against them. There are a number of wireless attacks to discuss on wireless. An important point to understand is that attackers will follow a process and methodology when they attempt an attack, and the way to defend against this is to stop information from getting to the potential attacker. This can be a challenge when it comes to wireless. We group the attacks into several different categories. They are listed in the following table:

Probing and network discovery


Denial of Service


Rogue access point
