Summary


In this chapter, we looked at a number of tools that we can be used to survey our wireless zone. We have seen how we could detect the channel on which the access points were running as well as the protection scheme that is enabled, be it WEP, or WPA. Additionally, we can also discover which clients are connected to the network, and the IP address range of the network.

Finally, we saw that disabling the SSID broadcast on wireless in itself has limited value, and as such, it is better to leave it enabled.

In the next chapter, we will look at examples of how attackers can break wireless security. It is very important that we discuss how broken security is breached, and then we can see how to protect it.
