Layer 2 security methods that a Wi-Fi enabled device supports
You can configure a Wi-Fi®
device to use security methods for layer 2 (also known as the IEEE® 802.11™
link layer) so that the device and a wireless access point can encrypt data that they send between them and authenticate the user. The device supports the following layer 2 security methods:
- open (no security method)
WEP encryption (64-bit and 128-bit)
- PSK protocol
802.1X™ standard and EAP authentication using EAP-FAST,
LEAP, and PEAP
- TKIP and AES-CCMP encryption for WPA™-Personal, WPA2™-Personal, WPA™-Enterprise, and WPA2™-Enterprise
To support layer 2 security methods, the device has a built-in IEEE
If your organization’s enterprise Wi-Fi network uses EAP authentication, you can permit and deny device access to the enterprise Wi-Fi network by updating your organization’s central authentication server. You are not required to update the configuration of each access point.

802.11 and IEEE
