Security controls map
Power Manager uses fine-grained instrumentation to provide increased
visibility to power consumption, anomalies, and utilization. Power Manager
alerts and reports about power and thermal events in servers, chassis, and
custom groups consisting of servers and chassis. This reporting enables
increased control, faster response times, greater accuracy, and broader
decisionmaking intelligence than is otherwise possible. **Figure
- Security control map for Power Manager plug-in
Authentication
Access control settings provide protection of resources against unauthorized access. Only Administrators, Device Managers, and Viewers have access to Power Manager plug-in features with appropriate roles and privileges configured. For feature-based access details, see the OpenManage Enterprise Power Manager and OpenManage Enterprise User’s Guide.
Rest API security
For the rest API security-related information, see the Security section in OpenManage Enterprise Power Manager RESTful API Guide.
Login security settings
There are various security configurations available in OpenManage Enterprise which when applied in OpenManage Enterprise gets automatically applied to Power Manager plug-in. For example, you can provide an IP range where only the devices that are specified in the IP range can access OpenManage Enterprise, block a user by specifying the username or an IP address, or lock a user for a specific duration after multiple failed attempts. For more details, see the Set the login security properties topic in OpenManage Enterprise User’s Guide.
User and credential management
Each user is assigned certain privileges that determine their access level in OpenManage Enterprise. For information about the user roles and feature-based access privileges for OpenManage Enterprise and Power Manager, see the OpenManage Enterprise User’s Guide and OpenManage Enterprise Power Manager User’s Guide.
Role and scope-based access
OpenManage Enterprise has Role Based Access Control (RBAC) that clearly defines the user privileges for the three built-in roles—Administrator, Device Manager, and Viewer. Additionally, using the Scope-Based Access Control (SBAC) an administrator can limit the device groups that a device manager has access to. The following topics further explain the RBAC and SBAC features.
Role-based access control (RBAC) privileges
Users are assigned roles which determine their level of access to the appliance settings and device management features. This feature is termed as Role-Based Access Control (RBAC). The console enforces the privilege required for a certain action before allowing the action.
This table lists the various privileges that are enabled for each role.

Scope-based access control (SBAC)
With the use of Role-Based Access Control (RBAC) feature, administrators can
assign roles while creating users. Roles determine their level of access to
the appliance settings and device management features. Scope-based Access
Control (SBAC) is an extension of the RBAC feature that allows an
administrator to restrict a Device Manager role to a subset of device groups
called scope.
While creating or updating a Device Manager (DM) user, administrators can
assign scope to restrict operational access of DM to one or more system
groups, custom groups, and / or plugin groups.
Administrator and Viewer roles have unrestricted scope. That means they have
operational access as specified by RBAC privileges to all devices and groups
entities.
Scope can be implemented as follows:
- Create or Edit User
- Assign DM role
- Assign scope to restrict operational access
A natural outcome of the SBAC functionality is the Restricted View feature. With Restricted View, particularly the Device Managers will see only the following:
- Groups (therefore, the devices in those groups) in their scope.
- Entities that they own (such as jobs, firmware or configuration templates and baselines, alert policies, profiles, and so on).
- Community entities such as Identity Pools and VLANs which are not restricted to specific users and can be used by everyone accessing the console.
- Built-in entities of any kind.
It should be noted that if the scope of a Device Manager is ‘unrestricted’,
then that Device Manager can view all the devices and groups, however, would
only be able to see the entities owned by him/her such as jobs, alert
policies, baselines, and so on along with the community and built-in entities
of any kind.
When a Device Manager (DM) user with an assigned scope logs in, the DM can see
and manage scoped devices only. Also, the DM can see and manage entities such
as jobs, firmware or configuration templates and baselines, alert policies,
profiles and so on associated with scoped devices, only if the DM owns the
entity (DM has created that entity or is assigned ownership of that entity).
For more information about the entities a DM can create, see Role-Based Access
Control (RBAC) privileges in OpenManage Enterprise.
In OpenManage Enterprise, scope can be assigned while creating a local or
importing AD/LDAP user. Scope assignment for OIDC users can be done only on
Open ID Connect (OIDC) providers.
SBAC for local users
While creating or editing a local user with DM role, admin can select one
or more device groups that defines the scope for the DM.
For example, you (as an administrator) create a DM user named dm1 and assign
group g1 present under custom groups. Then dm1 will have operational access to
all devices in g1 only. The user dm1 will not be able to access any other
groups or entities related to any other devices.
Furthermore, with SBAC, dm1 will also not be able to see the entities created
by other DMs (let’s say dm2) on the same group g1. That means a DM user will
only be able to see the entities owned by the user.
For example, you (as an administrator) create another DM user named dm2 and
assign the same group g1 present under custom groups. If dm2 creates
configuration template, configuration baselines, or profiles for the devices
in g1, then dm1 will not have access to those entities and vice versa.
A DM with scope to All Devices has operational access as specified by RBAC
privileges to all devices and group entities owned by the DM.
SBAC for AD/LDAP users
While importing or editing AD/LDAP groups, administrators can assign scopes to
user groups with DM role. If a user is a member of multiple AD groups, each
with a DM role, and each AD group has distinct scope assignments, then the
scope of the user is the union of the scopes of those AD groups.
For example,
- User dm1 is a member of two AD groups (RR5-Floor1-LabAdmins and RR5-Floor3-LabAdmins). Both AD groups have been assigned the DM role, with scope assignments for the AD groups are as follows: RR5-Floor1-LabAdmins gets ptlab-servers and RR5-Floor3-LabAdmins gets smdlab-servers. Now the scope of the DM dm1 is the union of ptlab-servers and smdlabservers.
- User dm1 is a member of two AD groups (adg1 and adg2). Both AD groups have been assigned the DM role, with scope assignments for the AD groups as follows: adg1 is given access to g1 and adg2 is given access to g2. If g1 is the superset of g2, then the scope of dm1 is the larger scope (g1, all its child groups, and all leaf devices).
When a user is a member of multiple AD groups that have different roles, the
higher-functionality role takes precedence (in the order Administrator, DM,
Viewer).
A DM with unrestricted scope has operational access as specified by RBAC
privileges to all device and group entities.
SBAC for OIDC users:
Scope assignment for OIDC users does not happen within the OpenManage
Enterprise console. You can assign scopes for OIDC users at an OIDC provider
during user configuration. When the user logs in with OIDC provider
credentials, the role and scope assignment will be available to OpenManage
Enterprise. For more information about configuring user roles and scopes, see
Configure an OpenID Connect provider policy in PingFederate for role section
in OpenManage Enterprise User’s Guide.
Transfer ownership: The administrator can transfer owned resources from a
device manager (source) to another device manager. For example, an
administrator can transfer all the resources assigned from a source dm1 to
dm2. A device manager with owned entities such as firmware and/or
configuration baselines, configuration templates, alert policies, and profiles
is considered an eligible source user. Transfer of ownership transfers only
the entities and not the device groups (scope) owned by a device manager to
another. For more information see, Transfer of ownership of Device Manager
entities section in OpenManage Enterprise User’s Guide.
Data security
The data that is maintained by Power Manager is stored and secured in internal
databases within the appliance and it cannot be accessed from outside. The
data that is transferred through Power Manager is secured by secure
communication channel.
Cryptography
Sensitive data is encrypted and stored in an internal database. For more
information, see the Security features in OpenManage Enterprise section in
OpenManage Enterprise User’s Guide.
Auditing and logging
Power Manager lists all the actions that are performed on the monitored
devices in audit logs. Use the OpenManage Enterprise console to generate the
audit logs with all the relevant information. You can export the audit log
files to a CSV file format.
Alerting
Automate your actions for the alerts generated, manage the alerts and forward
the alerts that are generated in OpenManage Enterprise. For more information,
see the Alert policies section in OpenManage Enterprise User’s Guide.
