Compromising WPA and WPA2 networks
Many organizations would configure their wireless routers and access points to operate within autonomous mode, which means that each access point is independent of the other. This creates an issue when IT professionals have to make administrative changes to the wireless network as they will need to log in to each access point to make the configuration change.
However, in many instances where the access points are operating in autonomous mode, their wireless security configurations are usually set to WPA2-PSK (personal mode). This allows IT professionals to configure a single password/passphrase on the access point that is shared with anyone who wants to access the wireless network. Using WPA2-PSK is recommended for small networks such as home users and small organizations with few users. However, there are many medium to large organizations that use this wireless security mode.
As you can imagine, if many users are sharing the same password...
