Implementing Wireless Network Security
In the previous chapter, we learned about network protocols, such as LAN, IP, and TCP/UDP-based attacks, in which the attacker targets network-based protocols, and how to protect against them. This chapter talks about wireless-based attacks and how to harden your wireless networks against them. By the end of this chapter, you will understand the risks to wireless networks and devices and know how to protect against these risks.
In wireless networks, we focus on protocols such as IEEE 802.11, various bands, such as /b/g/n (as discussed in the Wireless standards – IEEE 802.11 section), encryption standards, such as WEP, WPA, and WPA2, and their key weaknesses, such as creating rogue Access Points (APs), dumping hashes, and automating complete tasks. We also need to know how we can protect ourselves against these attacks.
This chapter starts with an explanation of the WLAN protocol—what the WLAN frame constitutes, the frames to...
