7.3.2 RADIUS Authentication
Part of NERC conformity is the ability to have centralized password authentication and
control. The basic way this feature works is that once enabled, all access into the IMACS shelf
is done through a password validation with a single point of control, the RADIUS
Authentication Server. Turning on this feature will deny all access to the IMACS unless
approved by the authentication server. The password authentication includes encryption of the
password string using the shared secret key. To enable the RADIUS authentication feature,
carriage return on the active CPU, and select 'A' for RADIUS. A screen such as below will
appear.
Figure 7-3.RADIUS options
To turn on RADIUS authentication, set the state to enabled. The user then needs to configure
the following:
