The following WLAN security policies are available: Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, and WLAN Authentication and Privacy Infrastructure (WAPI). Each security policy has a series of security mechanisms, including link authentication used to establish a wireless link, user authentication used when users attempt to connect to a wireless network, and data encryption used during data transmission. The following table lists the WLAN security policies.
Carriers can combine WLAN security policies with port authentication to enhance security of wireless users. Port authentication methods include 802.1X authentication, MAC address authentication, and Portal authentication. For details about the authentication methods, see "NAC Configuration (Unified Mode)" in the S2720, S5700, and S6700 V200R019C10 Configuration Guide > User Access and Authentication Configuration Guide.
