EAP-PEAP(MSCHAPv2) -- Secure? Alternatives? Cross-Platform?

Hi Folks,


We have a potential consultant recommending that we use EAP- PEAP(MSCHAPv2) and an appropriate supplicant in order to authenticate our wireless computers.


A few questions:


--Does this protocol work with or replace RADIUS authentication?

--Is it secure? I seem to recall that MSCHAPv2 was broken a long time ago?

--Does it work on Mac, PC, Linux?

--Are there viable alternatives? EAP-GTC?

Configured correctly it is secure. There are ways to misconfigure it in a manner that is insecure, however. Those protocols work over radius, so radius is not something separate, it is the delivery mechanism.

Please see the document here for more ideas:

If security is a concern, EAP-TLS is the only recommended EAP method.
