Access control

After you configure the Security plugin to use your own certificates and preferred authentication backend, you can start adding users, creating roles, and mapping roles to users.

This section of the documentation covers what a user is allowed to see and do after successfully authenticating.


Term Description
Permission An individual action, such as creating an index (e.g. indices:admin/create). For a complete list, see Permissions.
Action group A set of permissions. For example, the predefined SEARCH action group authorizes roles to use the _search and _msearch APIs.
Role Security roles define the scope of a permission or action group: cluster, index, document, or field. For example, a role named delivery_analyst might have no cluster permissions, the READ action group for all indices that match the delivery-data-* pattern, access to all document types within those indices, and access to all fields except delivery_driver_name.
Backend role (Optional) Arbitrary strings that you specify or that come from an external authentication system (e.g. LDAP/Active Directory). Backend roles can help simplify the role mapping process. Rather than mapping a role to 100 individual users, you can map the role to a single backend role that all 100 users share.
User Users make requests to OpenSearch clusters. A user has credentials (e.g. a username and password), zero or more backend roles, and zero or more custom attributes.
Role mapping Users assume roles after they successfully authenticate. Role mappings, well, map roles to users (or backend roles). For example, a mapping of kibana_user (role) to jdoe (user) means that John Doe gains all the permissions of kibana_user after authenticating. Likewise, a mapping of all_access (role) to admin (backend role) means that any user with the backend role of admin gains all the permissions of all_access after authenticating. You can map each role to many users and/or backend roles.

The security plugin comes with a number of predefined action groups, roles, mappings, and users. These entities serve as sensible defaults and are good examples of how to use the plugin.
