8 SECURITY
In cases where user attributable access is required especially to facilitate auditable processes for compliance reasons, use
RADIUS authentication only.
When the "Remote" 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 are displayed in plain text by the EnerVista software or UR device, nor are they ever
transmitted without cryptographic protection.
Only (TCP/UDP) ports and services that are needed for device configuration and for customer enabled features are
open. All the other ports are closed. For example, Modbus is on by default, so its TCP port number, 502, is open.
But if Modbus is disabled, port 502 is closed. This function has been tested and no unused ports have been found
NOTE
open.
