• CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.
2.2.0.1 EnerVista security
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a
substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security
management system is disabled by default to allow the administrator direct access to the EnerVista software after
installation. It is recommended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
2.2.0.2 Password security
Password security is a basic security feature present by default.
Two levels of password security are provided: command and setting. Use of a password for each level controls whether all
users can enter commands and/or change settings.
Two types of connection security are provided: password entry from local or remote connection. Local access is defined as
any access to settings or commands via the front panel interface. This includes both keypad entry and the through a front
panel port. Remote access is defined as any access to settings or commands via any rear communications port. This
includes both Ethernet and RS485 connections. These two settings are on by default and apply to all users.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the D30, the remote password is used. If the
connection is to a front panel port, the local password applies. (These two local and remote password settings are not
shown the figure.)
Password access events are logged in the Event Recorder.

2.2.0.3 CyberSentry security
CyberSentry security is available using software options that provide advanced security services. When an option is
purchased, the basic password security is disabled automatically.
CyberSentry provides security through the following features:
•
An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards-
based strong cryptography for authentication and credential protection
