RADIUS Authentication

The RADIUS authentication method is very similar to the

SecurID authentication method in that it uses a trusted third

party to authenticate tunnels between VPN Clients and VPN

devices. The trusted third party is a RADIUS Authentication

Server. When a VPN Client attempts to establish a tunnel with a

VPN device, the VPN device asks the VPN Client to provide its

RADIUS user name and password. The VPN device then uses its

own secret key to contact the RADIUS Authentication Server to

verify the VPN Client's identity.

There is a second type of RADIUS server supported by the HP

VPN suite: a RADIUS Accounting Server. This server keeps track

of those remote users who have established connections to VPN

devices, and the amount of time each connection is maintained.

It is not necessary to have a RADIUS Accounting Server to use

the RADIUS method of authentication.
