Security
The following security features are available:
•
Basic Security – The basic security feature present in the default offering of the
product.
• CyberSentry – The feature refers to the advanced security options available as a
software option. When this option is purchased, it is automatically enabled and Basic
Security is disabled.
GENERAL RULES FOR ROLES
• All the roles are password protected, except for the Observer role which is user
defined on the device. A user with Observer capability defined on the Radius is
password protected.
• All the roles, except for the Observer role, support only one session at one time.
• The Observer role has read-only access to all values in the relay except for one service
command which is described in the Password Recovery Procedure section.
• All the roles, except for the Observer, have access to a “log out” setting, which has the
effect of switching to Observer role.
• A Setpoint access setting for bypassing security is available. If this feature is used, the
user gains total access for any operations / configuration changes executed either
from the front panel or from EnerVista.
• The setpoint access setting may be either switched directly on or assigned to a digital
input.
• If the setpoint access setting is assigned to a digital input, the digital input needs to be
activated through a physical key (jumper).
• The setpoint access setting may be set only by an Administrator.
PASSWORD COMPLEXITY
The password complexity is available on both Basic Security and CyberSentry.
If password complexity is enabled, a user account requires an alpha-numeric password
that meets the following requirements:
•
Passwords cannot contain the user account name or parts of the user's full name that
exceed two consecutive characters
