Mode of Operation
EAP-TTLS consists of two phases:
• In phase 1, a TLS-encrypted channel between the SND Server
and the RADIUS server will be established. Only the RADIUS
server authenticates itself on the SND Server using a certificate
that was signed by a CA. This process is also referred to as 'outer
authentication'.
• In phase 2, an additional authentication method is used for the
communication within the TLS channel. EAP-defined methods
and older methods (CHAP, PAP, MS-CHAP und MS-CHAPv2) are
supported. This process is also referred to as 'inner
authentication'.
The advantage of this procedure is that only the RADIUS server
needs a certificate. Therefore no PKI is needed. Moreover, TTLS
supports most authentication protocols.
Requirements
; The TPG is defined as user (with user name and password) on a
RADIUS server.
Proceed as follows:
1. Start the mySND Control Center.
2. Select SECURITY – Authentication.
3. Select TTLS from the Authentication method list.
4. Enter the user name and the password that are used for the
configuration of the SND Server on the RADIUS server.
5. Select the settings intended to secure the communication in the
TLS channel.
6. To make the connection more secure, you can also install the
root certificate of the RADIUS server on the SND Server (Ö81).
7. Click Save & Restart to confirm.
ª The settings will be saved.
