WPA-Enterprise is designed for large businesses and requires a RADIUS authentication server that provides automatic key generation and authentication throughout the entire
All wireless devices, such as mobile phones and laptop computers, in the same hotspot use the same 256-bit pre-shared key (PSK), called as WPA2/PSK. WPA-Personal is for home and small office use, requiring no authentication server. There are two modes for WPA2 targeting the different users: WPA-Personal and WPA-Enterprise. WPA2 is considered a Robust Security Network (RSN) capable protocol because of supporting the process of authentication and exchange of cryptographic keys between station (STA) and Access Point (AP). WPA2 now is widely deployed in Wi-Fi communication to combat wireless attacks due to its efficiency and security. Wi-Fi Protected Access (WPA) is the evolved version of WEP. have discusses the entire process of cracking WEP encryption on Wi-Fi networks, focusing on manipulating some scanning tools, such as: Cain, NetStumbler, Kismet, and MiniStumbler, to assist ethical hackers or security profesionals in investigating wireless security and testing to strengthen security.
