Role Based Access Control

RBAC Definition

Role-based access control is a way to assign different levels of access to the users that define the features they can access.

RBAC is supported by MasterPact MTZ and ComPacT NSX circuit breakers only.

Access to the IFE interface is checked by RBAC mechanism when the connection is made through:

IFE interface webpages
EcoStruxure Power Commission (EPC) software

For information about enabling RBAC when the connection is made through EPC software, refer to IP Network Services .

Role Definition

The following roles are defined for remote access by default:

Security Administrator (SECADM)
Engineer
Installer
Operator
Viewer

The security administrator assigns a role to each of the users. Each role includes a set of permissions for the IFE interface users.

The security administrator can manage the users of IFE interface:

On the IFE interface webpages
With the EcoStruxure Cybersecurity Admin Expert (CAE) software

EcoStruxure Cybersecurity Admin Expert Software

Cybersecurity Admin Expert (CAE) software is used for security configuration of the IFE interface with firmware version 004.009.000 and later.

The security administrator can use CAE software to:

Manage the users of IFE interface
Define the security policy of the IFE interface
Upload security configurations to multiple IFE interfaces
Change Device Specific Settings (DSS) of each IFE interface independently

For more information, refer to EcoStruxure Cybersecurity Admin Expert Guide .

NOTE:

Enable HTTPS for secure transfer of configurations from CAE software to IFE interface.
Enable DPWS for discovery of the IFE interface on CAE software.

CAE Software Settings

The security administrator can set the following parameters in the CAE software:

Parameter	Description	Value
Minimum inactivity period	After this duration without any action from the user, IFE interface webpages are locked.	Range: 1–3600 s Default value: 600 s
Maximum login attempts	The maximum login attempts	Range: 1–32 Default value: 3
Locking period duration	After this duration the locked user account will be unlocked.	Range: 0–3600 s Default value: 60 s
LoggingPolicy	Enabled to enable the user account	Default setting: Disabled
	SyslogServerIPAddress to enter the server IP address of the Syslog server.	–
	SyslogServerport to enter the Syslog server port number.	Range: 1–65534 Default value: 601
Device measure read permission	Enabled while creating a role.	Default setting: Disabled

NOTE: CAE software supports a maximum of 12 users and 10 user roles for the IFE Interface.

CAE Device Specific Settings

The Device Specific Settings (DSS) is unique to the IFE interface which enables the configuration to be tailored for each individual device. For example, by using this feature it is possible to activate Modbus secure on a specific IFE interface while leaving it inactive on others.

The following device specific settings are available on the CAE software:

Parameter	Description	Default Setting
DPWS Discovery Status	Activates DPWS discovery on the IFE interface.	Enabled
FTP Server Status	Activates FTP server on the IFE interface.	Disabled
Modbus Secure Status	Activates Modbus secure on the IFE interface.	Disabled
Modbus TCP Status	Activates Modbus TCP on the IFE interface.	Enabled

Permission for Each Role

The security administrator can modify the permissions for each role using the CAE software.

The following table describes the permissions allowed for each role by default:
