WPA2 makes use of 128-bit encryption keys and dynamic session keys to guarantee the privacy of wireless networks as well as enterprise security. WPA2 Enterprise usually verifies network users through a RADIUS server or it may also use other authentication servers. WPA Enterprise authentication is usually required in corporate or government environments. WPA2 makes use of CCMP (Counter Cipher Mode with Block-Chaining Message Authentication Code Protocol) and AES (Advanced Encryption Standard) algorithms in order to provide more security to the business enterprises. WPA2-Enterprise has been around since 2004 and is still a gold standard for wireless network security by delivering over-the-air encryption and top-level security. WPA2 Enterprise makes use of IEEE 802.1x, which offers enterprise-grade authentication. The chief difference between WPA2 and WPA is that the former further improves the security of a network as it requires using an even more powerful encryption method called the AES. Wi-Fi Protected Access 2 is a network security technology generally used on Wi-Fi networks.WPA2 is an advancement of the WPA Network Protocol. WPA2 is the most recent security protocol developed by the Wi-Fi Alliance.
