API

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

Table of contents

  1. TOC {:toc}

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:

plugins.security.restapi.roles_enabled: ["<role>", ...]

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

plugins.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 _plugins/_security/api/roles or _plugins/_security/api/internalusers:

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

plugins.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, modify config/opensearch-security/internal_users.yml and run plugins/opensearch-security/tools/securityadmin.sh.

Create user

Introduced 1.0 {: .label .label-purple }

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 opendistro_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.

}

Sample response

}

Due to word boundaries associated with Unicode special characters, the Unicode standard analyzer cannot index a text field type value as a whole value when it includes one of these special characters. As a result, a text field value that includes a special character is parsed by the standard analyzer as multiple values separated by the special character, effectively tokenizing the different elements on either side of it.

For example, since the values in the fields "user.id": "User-1" and "user.id": "User-2" contain the hyphen/minus sign, this special character will prevent the analyzer from distinguishing between the two different users for user.id and interpret them as one and the same. This can lead to unintentional filtering of documents and potentially compromise control over their access.

To avoid this circumstance, you can use a custom analyzer or map the field as keyword, which performs an exact-match search. See Keyword field type for the latter option.

For a list of characters that should be avoided when field type is text, see Word Boundaries. {: .warning}

Patch configuration

Introduced 1.0 {: .label .label-purple }

Updates the existing configuration using the REST API. This operation can easily break your existing configuration, so we recommend using securityadmin.sh instead, which is far safer. See Access control for the API for how to enable this operation.

Before you can execute the operation, you must first add the following line to opensearch.yml:

plugins.security.unsupported.restapi.allow_securityconfig_modification: true

Request

PATCH _plugins/_security/api/securityconfig

Distinguished names

These REST APIs let a super admin add, retrieve, update, or delete any distinguished names from an allow list to enable communication between clusters and/or nodes.

Before you can use the REST API to configure the allow list, you must first add the following line to opensearch.yml:

plugins.security.nodes_dn_dynamic_config_enabled: true

Get distinguished names

Retrieves all distinguished names in the allow list.

Request

GET _plugins/_security/api/nodesdn

Sample response

{
  "cluster1": {
    "nodes_dn": [
      "CN=cluster1.example.com"
    ]
  }
}

To get the distinguished names from a specific cluster's or node's allow list, include the cluster's name in the request path.

Request

GET _plugins/_security/api/nodesdn/<cluster-name>

{
  "cluster3": {
    "nodes_dn": [
      "CN=cluster3.example.com"
    ]
  }
}

    }
  ]
}

Reload certificates

Introduced 1.0 {: .label .label-purple }

Reloads SSL certificates that are about to expire without restarting the OpenSearch node.

This call assumes that new certificates are in the same location specified by the security configurations in opensearch.yml. To keep sensitive certificate reloads secure, this call only allows hot reload with certificates issued by the same issuer and subject DN and SAN with expiry dates after the current certificate.

PUT _opendistro/_security/api/ssl/http/reloadcerts

Sample response
