Configuration
Distinguished names
Certificates
1. Get certificates
2. Reload transport certificates
Cache

1. Health check
Audit logs
1. Enable audit logs

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>", ...]

If you’re working with APIs that manage Distinguished names or Certificates that require super admin access, enable the REST API admin configuration in your opensearch.yml file as shown in the following setting example:

plugins.security.restapi.admin.enabled: true

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

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

Roles also allow you to control access to specific REST APIs. You can add individual or multiple cluster permissions to a role and grant users access to associated APIs when they are mapped to the role. The following list of cluster permissions includes the endpoints that correspond to the Security REST APIs:

Permission	APIs granted	Description
restapi:admin/actiongroups	`/actiongroup` and `/actiongroups`	Permission to get, delete, create, and patch actions groups (including bulk updates).
restapi:admin/allowlist	`/allowlist`	Permission to add any endpoints and HTTP requests to a list of allowed endpoints and requests.
restapi:admin/internalusers	`/internaluser` and `/user`	Permission to add, retrieve, modify, and delete any user in the cluster.
restapi:admin/nodesdn	`/nodesdn`	Permission to add, retrieve, update, or delete any distinguished names from an allow list and enable communication between clusters and/or nodes.
restapi:admin/roles	`/roles`	Permission to add, retrieve, modify, and delete any roles in the cluster.
restapi:admin/rolesmapping	`/rolesmapping`	Permission to add, retrieve, modify, and delete any roles-mapping.
restapi:admin/ssl/certs/info	`/ssl/certs/info`	Permission to view current Transport and HTTP certificates.
restapi:admin/ssl/certs/reload	`/ssl/certs/reload`	Permission to view reload Transport and HTTP certificates.
restapi:admin/tenants	`/tenants`	Permission to get, delete, create, and patch tenants.

Possible values for endpoint are:

ACTIONGROUPS
ROLES
ROLESMAPPING
INTERNALUSERS
CONFIG
CACHE
SYSTEMINFO
NODESDN
SSL

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.

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.

Patch configuration

Introduced 1.0

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
[
  {

Configuration upgrade check

Introduced 2.14

Checks the current configuration bundled with the host’s Security plugin and compares it to the version of the OpenSearch Security plugin the user downloaded. Then, the API responds indicating whether or not an upgrade can be performed and what resources can be updated.

With each new OpenSearch version, there are changes to the default security configuration. This endpoint helps cluster operators determine whether the cluster is missing defaults or has stale definitions of defaults.

Request

GET _plugins/_security/api/_upgrade_check

Example response

{
  "status" : "OK",
  "upgradeAvailable" : true,
  "upgradeActions" : {
    "roles" : {
      "add" : [ "flow_framework_full_access" ]
    }
  }
}

Response body fields

Field	Data type	Description
`upgradeAvailable`	Boolean	Responds with `true` when an upgrade to the security configuration is available.
`upgradeActions`	Object list	A list of security objects that would be modified when upgrading the host’s Security plugin.

Configuration upgrade

Introduced 2.14

Adds and updates resources on a host’s existing security configuration from the configuration bundled with the latest version of the Security plugin.

These bundled configuration files can be found in the <OPENSEARCH_HOME>/security/config directory. Default configuration files are updated when OpenSearch is upgraded, whereas the cluster configuration is only updated by the cluster operators. This endpoint helps cluster operator upgrade missing defaults and stale default definitions.

POST _plugins/_security/api/_upgrade_perform
{
  "configs" : [ "roles" ]
}

Request body fields

Field	Data type	Description	Required
`configs`	Array	Specifies the configurations to be upgraded. This field can include any combination of the following configurations: `actiongroups`,`allowlist`, `audit`, `internalusers`, `nodesdn`, `roles`, `rolesmappings`, `tenants`. Default is all supported configurations.	No

Example response

{
  "status" : "OK",

      "add" : [ "flow_framework_full_access" ]
    }
  }
}

Response body fields

Field	Data type	Description
`upgrades`	Object	A container for the upgrade results, organized by configuration type, such as `roles`. Each changed configuration type will be represented as a key in this object.
`roles`	Object	Contains a list of role-based action keys of objects modified by the upgrade.

Distinguished names

These REST APIs let a super admin (or a user with sufficient permissions to access this API) 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

Example request

GET

A GET call retrieves the audit configuration.

GET /_opendistro/_security/api/audit

PUT

A PUT call updates the audit configuration.

PUT /_opendistro/_security/api/audit/config
{
  "enabled": true,
  "audit": {
    "ignore_users": [],
    "ignore_requests": [],
    "disabled_rest_categories": [

    "write_metadata_only": true,
    "external_config": false,
    "internal_config": true
  }
}

PATCH

A PATCH call is used to update specified fields in the audit configuration. The PATCH method requires an operation, a path, and a value to complete a valid request. For details on using the PATCH method, see the following Patching resources description at Wikipedia.

Using the PATCH method also requires a user to have a security configuration that includes admin certificates for encryption. To find out more about these certificates, see Configuring admin certificates.

curl -X PATCH -k -i --cert <admin_cert file name> --key <admin_cert_key file name> <domain>/_opendistro/_security/api/audit -H 'Content-Type: application/json' -d'[{"op":"add","path":"/config/enabled","value":"true"}]'

OpenSearch Dashboards Dev Tools do not currently support the PATCH method. You can use curl, Postman, or another alternative process to update the configuration using this method. To follow the GitHub issue for support of the PATCH method in Dashboards, see issue #2343.

Example response

The GET call produces a response that appears similar to the following:

{
  "_readonly" : [
    "/audit/exclude_sensitive_headers",
    "/compliance/internal_config",
    "/compliance/external_config"
  ],
  "config" : {
    "compliance" : {
      "enabled" : true,
      "write_log_diffs" : false,
      "read_watched_fields" : { },
      "read_ignore_users" : [ ],
      "write_watched_indices" : [ ],
      "write_ignore_users" : [ ],
      "read_metadata_only" : true,
      "write_metadata_only" : true,
      "external_config" : false,
      "internal_config" : true
    },
    "enabled" : true,
    "audit" : {
      "ignore_users" : [ ],
      "ignore_requests" : [ ],
      "disabled_rest_categories" : [
        "AUTHENTICATED",
        "GRANTED_PRIVILEGES"
      ],
      "disabled_transport_categories" : [
        "AUTHENTICATED",
        "GRANTED_PRIVILEGES"
      ],
      "log_request_body" : true,
      "resolve_indices" : true,
      "resolve_bulk_requests" : true,
      "exclude_sensitive_headers" : true,
      "enable_transport" : true,
      "enable_rest" : true
    }
  }
}

The PUT request produces a response that appears similar to the following:

{
  "status" : "OK",
  "message" : "'config' updated."
