two factor authentication for a wifi network?

StackOverflow https://stackoverflow.com/questions/21324266

Question

is it possible to setup two factor authentication for known users of a wifi network? I imagine that this might add security to wifi networks whose keys are stored by an untrusted device or third party smartphone os-maker.

Solution

Yes we can apply on Cisco Router(as much as I know) and we have the following options:

  • OTP using external RADIUS server and RSA tokens
  • EAP-Chaining using the AnyConnect Agent and Cisco ISE
  • MAR (machine access restrictions). If the machine had not performed authentication the user will not be authorized
  • Layer 3 security on the Wireless LAN Controller
