Major attacks include such as, Sniffing, Key cracking, DoS (Denial of Service), Deauthentication attacks, War driving etc. This chapter is not focused on attacks, we shall mainly concentrate on best practices- how to install and use WLAN securely which can thwart a number of above mentioned attacks.

So make sure, your network is secured from being maliciously used.
There is no silver bullet that will protect your wireless network infrastructure. These are, however, some countermeasures listed below that should be used in conjunction with each other to secure your wireless network to the highest level:
