CHAPTER 4: SYSTEM CONFIGURATION Security Mechanism Client Support Implementation Considerations WPA over 802.1X Mode Requires WPA-enabled system and network card driver (native support provided in Windows XP) • Provides robust security in WPA-only mode (i.e., WPA clients only) • Offers support for legacy WEP clients, but with increased security risk (i.e., WEP authentication keys disabled) • Requires configured RADIUS server • 802.1X EAP type may require management of digital certificates for clients and server WPA PSK Mode Requires WPA-enabled system and network card driver (native support provided in Windows XP) • Provides good security in small networks • Requires manual management of pre-shared key WPA2 with 802.1X Requires WPA-enabled system and network card driver (native support provided in Windows XP) • Provides the strongest security in WPA2-only mode • Provides robust security in mixed mode for WPA and WPA2 clients • Offers fast roaming for time-sensitive client applications • Requires configured RADIUS server • 802.1X EAP type may require management of digital certificates for clients and server • Clients may require hardware upgrade to be WPA2 compliant WPA2 PSK Mode Requires WPA-enabled system and network card driver (native support provided in Windows XP) • Provides robust security in small networks • Requires manual management of pre-shared key • Clients may require hardware upgrade to be WPA2 compliant NOTE: You must enable data encryption through the web in order to enable all types of encryption (WEP, TKIP, or AES) in the access point. The access point can simultaneously support clients using various different security mechanisms. The configuration for these security combinations are outlined in the following table. Note that MAC address authentication can be configured independently to work with all security mechanisms and is indicated separately in the table. Required RADIUS server support is also listed.
