Users never deal with the actual encryption keys. Users are assigned login credentials they must present when connecting to the network, which can be modified or revoked by administrators at anytime. Though more complicated to set up, it offers individualized and centralized control over access to your Wi-Fi network. Enterprise (EAP/RADIUS) Mode: This mode provides the security needed for wireless networks in business environments.Therefore, anyone on the computer—whether it be employees or thieves—can connect to the network and also recover the encryption passphrase. Unlike with the Enterprise mode, the encryption passphrase is stored on the computers. This would be a big headache when you need to change it for instance, when an employee leaves the company or when any computers are stolen or compromised. If the global passphrase should need to be changed, it must be manually changed on all the APs and computers. Unlike with the Enterprise mode, wireless access can't be individually or centrally managed. Though this mode seems very easy to implement, it actually makes properly securing a business network nearly impossible. Then the passphrase must be entered by users when connecting to the Wi-Fi network. You define an encryption passphrase on the wireless router and any other access points (APs).

Personal or Pre-Shared Key (PSK) Mode: This mode is appropriate for most home networks—but not business networks.Now let's get started! Two Modes of WPA/WPA2: Personal (PSK) versus Enterpriseīoth versions of Wi-Fi Protected Access (WPA/WPA2) can be implemented in either of two modes: We'll see how and why you'd want to move from the easy-to-use Personal mode to the Enterprise mode. In this article, we'll discover the two very different modes of Wi-Fi Protected Access. The second version (WPA2), released in mid-2004, does provide complete security, however, because it fully implements the IEEE 802.11i security standard with CCMP/AES encryption. Although the first version (WPA), which uses TKIP/RC4 encryption, has gotten beaten up a bit, is not totally cracked, and can still be very secure. In 2003, the Wi-Fi Alliance released a security standard called Wi-Fi Protected Access. This first wireless LAN security standard, developed by the IEEE, has been vulnerable to cracking by Wi-Fi hackers for nearly a decade now. As you may know already, Wired Equivalent Privacy (WEP) security is not secure.
