Chapter Six: Security Call authentication 87
Call authentication
Call authentication enables ISDN devices, like the DIVA LAN ISDN Modem, to validate the identity of the
device at the other end of the line. Authentication works through the exchange of usernames and passwords. It
can be one-way (either the caller gets validated or the callee gets validated) or two-way (both sides validate
each other).
Generally, authentication is one-way, with the caller getting validated. For example:
• When the DIVA LAN ISDN Modem calls an ISP or a corporate network, it will be authenticated (i.e., it
must supply a username and password to log on).
• When a remote computer calls the DIVA LAN ISDN Modem, it will be authenticated (i.e., it must supply
a username and password for the call to be accepted).
To successfully use call authentication it is important that both devices are configured to support the same
authentication options.
To set up call authentication
1. On the Configuration main menu, click Connection Profiles.
2. Click Edit for the profile you want to configure.
3. Click Authentication on the menu bar. You will see the following page:
4. Specify the Local username and Local password this profile will send to the remote site during the
authentication process. For example, the ISP profile uses these values to log on to your ISP account.
Note Local username and Local password are case-sensitive.
5. Specify the type of password the DIVA LAN ISDN Modem will send to the remote: encrypted or any
(unchecked). If the remote is not using the same type of encryption, the call will be rejected.
Note This setting applies to outgoing calls only.
6. Enable Always authenticate the remote if you want the DIVA LAN ISDN Modem to ask the remote to
identify itself with a username and password. The DIVA LAN ISDN Modem will compare the values the
remote sends against the settings you make for Remote username and Remote password. Remote
username and Remote password are case-sensitive.
Note This setting applies to outgoing calls only. The DIVA LAN ISDN Modem always authenticates the
remote when receiving an incoming call.
