API

The security plugin REST API lets you programmatically create and manage users, roles, role mappings, action groups, and tenants.

Access control for the API

Just like OpenSearch permissions, you control access to the security plugin REST API using roles. Specify roles in opensearch.yml:

opensearch_security.restapi.roles_enabled: ["<role>", ...]

These roles can now access all APIs. To prevent access to certain APIs:

opensearch_security.restapi.endpoints_disabled.<role>.<endpoint>: ["<method>", ...]

Possible values for endpoint are:

  • ACTIONGROUPS
  • ROLES
  • ROLESMAPPING
  • INTERNALUSERS
  • CONFIG
  • CACHE
  • LICENSE
  • SYSTEMINFO

Possible values for method are:

  • GET
  • PUT
  • POST
  • DELETE
  • PATCH

For example, the following configuration grants three roles access to the REST API, but then prevents test-role from making PUT, POST, DELETE, or PATCH requests to _opensearch/_security/api/roles or _opensearch/_security/api/internalusers:

opensearch_security.restapi.roles_enabled: ["all_access", "security_rest_api_access", "test-role"]
opensearch_security.restapi.endpoints_disabled.test-role.ROLES: ["PUT", "POST", "DELETE", "PATCH"]
opensearch_security.restapi.endpoints_disabled.test-role.INTERNALUSERS: ["PUT", "POST", "DELETE", "PATCH"]

To use the PUT and PATCH methods for the configuration APIs, add the following line to opensearch.yml:

opensearch_security.unsupported.restapi.allow_securityconfig_modification: true

Reserved and hidden resources

You can mark users, role, role mappings, and action groups as reserved. Resources that have this flag set to true can't be changed using the REST API or OpenSearch Dashboards.

To mark a resource as reserved, add the following flag:

kibana_user:
  reserved: true

Likewise, you can mark users, role, role mappings, and action groups as hidden. Resources that have this flag set to true are not returned by the REST API and not visible in OpenSearch Dashboards:

kibana_user:
  hidden: true

Hidden resources are automatically reserved.

To add or remove these flags, you need to modify plugins/opensearch-security/securityconfig/internal_users.yml and run plugins/opensearch-security/tools/securityadmin.sh.


Account

Get account details

Returns account details for the current user. For example, if you sign the request as the admin user, the response includes details for that user.

  }

Users

These calls let you create, update, and delete internal users. If you use an external authentication backend, you probably don't need to worry about internal users.

Get user

Request

GET _opensearch/_security/api/internalusers/<username>

Sample response

{
  "kirk": {
    "hash": "",
    "roles": [ "captains", "starfleet" ],

Delete user

Request

DELETE _opensearch/_security/api/internalusers/<username>

Sample response

{
  "status":"OK",

Create user

Creates or replaces the specified user. You must specify either password (plain text) or hash (the hashed user password). If you specify password, the security plugin automatically hashes the password before storing it.

Note that any role you supply in the opensearch_security_roles array must already exist for the security plugin to map the user to that role. To see predefined roles, refer to the list of predefined roles. For instructions on how to create a role, refer to creating a role.
