2.1.2 SECURITY
The following security features are available:
• Password security — Basic security present in the default offering of the product
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The fea-
ture is available in the default offering of the product and only in the EnerVista software.
• CyberSentry security — Advanced security options available as a software option. When purchased, the options are
automatically enabled, and the default Password security and EnerVista security are disabled.
a) 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 substa-
tion 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 recom-
mended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
b) PASSWORD SECURITY
Password security is a basic security feature present in the default offering of the product.
Two levels of password security are provided: command and setting.
The following operations are under command password supervision:
• Changing the state of virtual inputs
• Clearing the event records
• Clearing the oscillography records
• Changing the date and time
• Clearing energy records
