Recommendations
WPA with RADIUS
encryption algorithms used with WPA modes are far superior to the
for Static WEP or IEEE 802.1x modes. Therefore, CCMP (AES) or TKIP should be used
whenever possible. All WPA modes allow you to use these encryption schemes, so WPA
security modes are recommended above the others when using WPA is an option.
Additionally, this mode (WPA with RADIUS) incorporates a RADIUS server for user
authentication which gives it an edge over WPA-PSK.
Use the following guidelines for choosing options within the WPA with RADIUS security
mode:
The best security you can have to date on a wireless network is WPA with RADIUS
1.
using CCMP (AES) encryption algorithm. AES is a symmetric 128-bit block data
encryption technique that works on multiple layers of the network. It is the most effective
encryption system currently available for wireless networks. If all clients or other APs
on the network are WPA/CCMP compatible, use this encryption algorithm.
2.
The second best choice is WPA with RADIUS with the encryption algorithm set to
"Both" (that is, both TKIP and CCMP). This lets WPA client stations without CCMP
associate, uses TKIP for encrypting
to select whether to use CCMP or TKIP for
WPA configuration allows more interoperability, at the expense of some security. Client
stations that support CCMP can use it for their
to-station interoperability problems with the "Both" encryption algorithm setting, then
you will need to select TKIP instead.
The third best choice is WPA with RADIUS with the encryption algorithm set to TKIP.
3.
Some clients have interoperability issues with CCMP and TKIP enabled at the same
time. If you encounter this problem, then choose TKIP as the encryption algorithm.
This is the standard WPA mode, and most interoperable mode with client Wireless
software security features. TKIP is the only encryption algorithm that is being tested
in Wi-Fi WPA certification.
