Configuring Two-Factor Authentication

Two-factor authentication is an authentication method that requires two independent pieces of
information to establish identity and privileges. Two-factor authentication is stronger and more
rigorous than traditional password authentication that only requires one factor (the user's
password).
For more information on how two-factor authentication works see
Overview" section on page
Dell SonicWALL's implementation of two-factor authentication either uses two separate
RADIUS authentication servers, or partners with two of the leaders in advanced user
authentication: RSA and VASCO. If you are using RSA, you must have the RSA Authentication
Manager and RSA SecurID tokens. If you are using VASCO, you must have the VASCO
IdentiKey and Digipass tokens.
To configure two-factor authentication, you must first configure a RADIUS domain. For
information see
162 | SRA 6.0 Administrator's Guide
The SRA appliance will attempt to authenticate against the specified RADIUS server
using PAP authentication. It is generally required that the RADIUS server be
configured to accept RADIUS client connections from the SRA appliance. Typically,
these connections will appear to come from the SRA appliance X0 interface IP
address. Refer to your RADIUS server documentation for configuration instructions.
