Built-in roles
editBuilt-in roles
editThe Elastic Stack security features apply a default role to all users, including anonymous users. The default role enables users to access the authenticate endpoint, change their own passwords, and get information about themselves.
There is also a set of built-in roles you can explicitly assign to users. These roles have a fixed set of privileges and cannot be updated.
-
apm_system
- Grants access necessary for the APM system user to send system-level data (such as monitoring) to Elasticsearch.
-
apm_user
-
Grants the privileges required for APM users (such as
read
andview_index_metadata
privileges on theapm-*
and.ml-anomalies*
indices). [7.13.0] Deprecated in 7.13.0. See APM app users and privileges for alternatives. . -
beats_admin
-
Grants access to the
.management-beats
index, which contains configuration information for the Beats. -
beats_system
-
Grants access necessary for the Beats system user to send system-level data (such as monitoring) to Elasticsearch.

- This role automatically grants full access to new Kibana features as soon as they are released.
- Some Kibana features may also require creation or write access to data indices. Machine learning data frame analytics jobs is an example. For such features those privileges must be defined in a separate role.
-
enrich_user
-
Grants access to manage all enrich indices (
.enrich-*
) and all operations on ingest pipelines. -
ingest_admin
-
Grants access to manage all index templates and all ingest pipeline configurations.
This role does not provide the ability to create indices; those privileges must be defined in a separate role.

Grants access to the
.logstash*
indices for managing configurations, and grants necessary access for logstash-specific APIs exposed by the logstash x-pack plugin. -
logstash_system
-
Grants access necessary for the Logstash system user to send system-level data (such as monitoring) to Elasticsearch. For more information, see Configuring Security in Logstash.
- This role should not be assigned to users as the granted permissions may change between releases.
- This role does not provide access to the logstash indices and is not suitable for use within a Logstash pipeline.
-
machine_learning_admin
-
Provides all of the privileges of the
machine_learning_user
role plus the full use of the machine learning APIs. Grantsmanage_ml
cluster privileges, read access to.ml-anomalies*
,.ml-notifications*
,.ml-state*
,.ml-meta*
indices and write access to.ml-annotations*
indices. Machine learning administrators also need index privileges for source and destination indices and roles that grant access to Kibana. See Machine learning security privileges. -
machine_learning_user
-
Grants the minimum privileges required to view machine learning configuration,
status, and work with results. This role grants
monitor_ml
cluster privileges, read access to the.ml-notifications
and.ml-anomalies*
indices (which store machine learning results), and write access to.ml-annotations*
indices. Machine learning users also need index privileges for source and destination indices and roles that grant access to Kibana. See Machine learning security privileges. -
manage_enrich
- Grants privileges to access and use all of the enrich APIs. Users with this role can manage enrich policies that add data from your existing indices to incoming documents during ingest.
-
monitoring_user
-
Grants the minimum privileges required for any user of X-Pack monitoring other than those
required to use Kibana. This role grants access to the monitoring indices and grants
privileges necessary for reading basic cluster information. This role also includes
all Kibana privileges for the Elastic Stack monitoring features.
Monitoring users should also be assigned the
kibana_admin
role, or another role with access to the Kibana instance. -
remote_monitoring_agent
-
Grants the minimum privileges required to write data into the monitoring indices
(
.monitoring-*
). This role also has the privileges necessary to create Metricbeat indices (metricbeat-*
) and write data into them. -
remote_monitoring_collector
- Grants the minimum privileges required to collect monitoring data for the Elastic Stack.
-
reporting_user
- Grants the specific privileges required for users of X-Pack reporting other than those required to use Kibana. This role grants access to the reporting indices; each user has access to only their own reports. Reporting users should also be assigned additional roles that grant access to Kibana as well as read access to the indices that will be used to generate reports.
-
rollup_admin
-
Grants
manage_rollup
cluster privileges, which enable you to manage and execute all rollup actions. -
rollup_user
-
Grants
monitor_rollup
cluster privileges, which enable you to perform read-only operations related to rollups. -
snapshot_user
- Grants the necessary privileges to create snapshots of all the indices and to view their metadata. This role enables users to view the configuration of existing snapshot repositories and snapshot details. It does not grant authority to remove or add repositories or to restore snapshots. It also does not enable to change index settings or to read or update data stream or index data.
-
superuser
-
Grants full access to cluster management and data indices. This role also grants direct read-only access to restricted indices like
.security
. A user with thesuperuser
role can impersonate any other user in the system.On Elastic Cloud, all standard users, including those with the
superuser
role are restricted from performing operator-only actions.This role can manage security and create roles with unlimited privileges. Take extra care when assigning it to a user.
-
transform_admin
-
Grants
manage_transform
cluster privileges, which enable you to manage transforms. This role also includes all Kibana privileges for the machine learning features. -
transform_user
-
Grants
monitor_transform
cluster privileges, which enable you to perform read-only operations related to transforms. This role also includes all Kibana privileges for the machine learning features. -
transport_client
-
Grants the privileges required to access the cluster through the Java Transport Client. The Java Transport Client fetches information about the nodes in the cluster using the Node Liveness API and the Cluster State API (when sniffing is enabled). Assign your users this role if they use the Transport Client.
Using the Transport Client effectively means the users are granted access to the cluster state. This means users can view the metadata over all indices, index templates, mappings, node and basically everything about the cluster. However, this role does not grant permission to view the data in all indices.
-
viewer
-
Grants read-only access to all features in Kibana (including Solutions) and to data indices.
- This role provides read access to any index that is not prefixed with a dot.
- This role automatically grants read-only access to new Kibana features as soon as they are available.

Allows users to create and execute all Watcher actions. Grants read access to the
.watches
index. Also grants read access to the watch history and the triggered watches index. -
watcher_user
-
Grants read access to the
.watches
index, the get watch action and the watcher stats.
