WiFi Security: WEP, WPA, WPA2 And Their Differences - NetSpot
At this time the main vulnerability to a WPA2 system is when the attacker already has access to a secured WiFi network and can gain access to certain keys to perform an attack on other devices on the network. This being said, the security suggestions for the known WPA2 vulnerabilities are mostly significant to the networks of enterprise levels, and not really relevant for small home networks.
Why was WPA2 invented?
In order to enhance the security, WPA2 was invented with strong encryption model (AES) and a very strong authentication model based on 802.1x (or PSK).
