CyberSentry user authentication
The following types of authentication are supported by CyberSentry to access the UR device:
•
Device Authentication (local UR device authenticates)
• Server Authentication (RADIUS server authenticates)
The EnerVista software allows access to functionality that is determined by the user role, which comes either from the local
UR device or the RADIUS server.
The EnerVista software has a device authentication option on the login screen for accessing the UR device. When the
"Device" button is selected, the UR uses its local authentication database and not the RADIUS server to authenticate the
user. In this case, it uses its built-in roles (Administrator, Engineer, Supervisor, Observer, Operator, or Administrator and
Supervisor when Device Authentication is disabled) as login names and the associated passwords are stored on the UR
device. As such, when using the local accounts, access is not user-attributable.
In cases where user-attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication only.
When the "Server" Authentication Type option is selected, the UR uses the RADIUS server and not its local authentication
database to authenticate the user.
No password or security information is displayed in plain text by the EnerVista software or UR device, nor is such
information ever transmitted without cryptographic protection.
CyberSentry server authentication
The UR has been designed to direct automatically the authentication requests based on user names. In this respect, local
account names on the UR are considered as reserved and not used on a RADIUS server.
The UR detects automatically whether an authentication request is to be handled remotely or locally. As there are five local
accounts possible on the UR, if the user ID credential does not match one of the five local accounts, the UR forwards
automatically the request to a RADIUS server when one is provided.
If a RADIUS server is provided, but is unreachable over the network, server authentication requests are denied. In this
situation, use local UR accounts to gain access to the UR system.
